This poetics of ekphrasis, that is, the reproduction of one art form through the medium of another art form, such as a painting or a photograph or a poem of a sculpture, or, perhaps more commonly, a poem about a painting, is prevalent throughout the history of art and literature. First, there is the real-life object itself, even if in the painting or sculpture this exists only as an imitation of an ideal version of the object then there is the painting or the sculpture, a new object in itself, which is at a second remove and finally, the poem is a third remove (and if we are reading a work in translation, that would be a fourth remove). They shed light on our understanding of the original artworks and even on the objects or stories being portrayed, although this occurs from several removes. Such poems also offer critical readings and discussions of the original works. These two art forms have particularly engaged writers’ imaginations, often leading or prompting them to respond to works of visual art in response poems, which then become new artworks in and of themselves. Of course, image-obsessed cultures existed even before the advent of photography, when the predominant manifestations of visual mimesis were paintings and sculptures. Indeed, for an image that is ultimately only bytes of information, one might wonder whether an original version can even be said to exist. In this sense, modern photography can be seen as a form of Aristotelian mimesis highly facilitated by technology, and the more often an image is reproduced, the more the “aura” of its original suffers. Perhaps most importantly, today’s digital images lack the physicality of photographs of the past. They also often seem very formal and stiff compared to the images of today, although it must be said that many of the pictures we take continue to fall into specific genres (the group shot, the goofy V-sign common in Asia, the mirrored-selfie). Old photographs and their conventions are both familiar and foreign to us, with their alienated and uncanny appeal. Therefore it's just server-trust and SMS trust (ewww!) over and over and over again.Even a cursory poll of our security-conscious friends shows that no one bothers.Checking is infeasible, since it happens way too often.Undoubtedly these chat services would argue that it's good enough because the user is warned, and a user could notice and check the safety numbers if they wanted. You should be seeing a giant skull and crossbones. And make no mistake: TOFU isn't TOFU if it lets you keep going with a cute little shield that flows by. 8.8 has changed and you have requested strict checking. Offending RSA key in /Users/rmueller/.ssh/known_hosts: 12 Please contact your system administrator.Īdd correct host key in /Users/rmueller/.ssh/known_hosts to get rid of this message. It is also possible that a host key has just been changed. Someone could be eavesdropping on you right now (man-in-the-middle attack)! Similarly, in SSH, if a remote host's key changes, it doesn't "just work," it gets downright belligerent: WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! If a key has changed, each side sounds the alarm. Rather than meeting in person, you just trust a party in the middle to vouch for each side.and then, after the initial introduction, each side carefully tracks the keys to make sure nothing has changed. In cryptography, the term TOFU ("Trust on first use") describes taking a gamble the first time 2 parties talk. Looks like we got a security upgrade! (But not really.) Resets happen regularly enough that these apps make it look like no big deal: If you have just dozens of contacts, resets will affect you every few days. Reinstall the app, or (6) when any partner uninstalls and reinstalls. With those apps, you throw away the crypto and just start trusting the server: (1) whenever you switch to a new phone (2) whenever any partner switches to a new phone (3) when you factory-reset a phone (4) when any partner factory-resets a phone, (5) whenever you uninstall and How often do resets happen? Answer: if you're using most encrypted chat apps, all the freaking time. How often do you find yourself skipping this check, even though there can be no safety against a man-in-the-middle attack without it?Įven if you are serious about safety numbers, you might only see your chat partners once a year at a conference, so you're stuck. You must now reestablish identity, and in almost all cases, this means meeting in person and comparing "safety numbers" with every last one of your contacts. After a reset, you clear your public keys, and you become a cryptographic stranger in all your conversations. When users lose their keys, they need to reset theirĪccount "resets" are dangerous. In end-to-end (E2E) encrypted chat apps, users take charge of their own keys. To resolve this issue, try VLC media player. MP4 is a container that contains various kinds of data, so when there is a problem opening the file, it usually means that data in the container (an audio or video codec) is not compatible with the device’s OS. On some devices, particularly mobile, opening this file type can be problematic. On Windows, it opens in Windows Media Player. There is no need for third-party software. Simply double-clicking the file opens it. MP4 files open in the operating system's default video player. Many consider MP4 to be one of the best video formats available today. It is also a popular video format for streaming over the Internet, such as on YouTube. It is compatible with a wide range of devices and operating systems, using a codec to compress file size, resulting in a file that is easy to manage and store. MPEG-4 (MP4) is a container video format that can store multimedia data, usually audio and video. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. This is important because MKV is not an industry standard, which means that other media players might not support it.Īdditionally, MKV does not use codecs to compress file size, which means the file can be quite large. This media player is compatible with all operating systems and platforms. 2 Convert MKV to MP4 Your video will automatically convert from MKV to MP4, and you will be able to preview the converted file afterwards. The best way to open an MKV file is to use VLC media player. Select a MKV file Drag & drop or click ‘Select File’ to upload from your device to get started with our free online MKV to MP4 converter. The name derives from “ Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another. Since it is open source, a user can customize it with open-source software. Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format.

The SIP Forum is uniquely positioned to take the lead in turning this vision into reality and ushering in an era of trusted cross-border calling and messaging."Īs a member of the Board of Directors, Cray will help provide guidance and overall governance of all SIP Forum operations. "Now it's time to extend that trust model to the world with a new global framework that CSPs everywhere can use to vet their trading partners and the traffic they generate. "STIR/SHAKEN highlights the value of an authoritative verification framework that all CSPs can leverage to protect their consumer and enterprise customers against spoofing and other fraud," Cray said. I look forward to working with George and the rest of the SIP Forum Board of Directors to continue to provide the industry with even more innovative technologies and best practices." That work is paying off, and iconectiv has been a major contributor in that effort. "A prime example is our collaboration with ATIS to develop STIR/SHAKEN, which the FCC subsequently mandated in 2020. "For years, one of the SIP Forum's top priorities has been helping the telecom ecosystem mitigate the scourge of illegal robocalls and caller ID spoofing," said SIP Forum President and Managing Director Marc Robins.

The SIP-based STIR/SHAKEN call authentication framework has played an instrumental role in turning the tide by enabling CSPs to verify that caller ID information transmitted with a call matches the caller's real phone number. This trend is steadily restoring consumer trust in caller ID, making consumers more inclined to answer important calls from their doctor, school, insurance provider and other legitimate businesses rather than letting them drop into voicemail. And by 2025, fraudulent losses arising from robocalling are anticipated to decline for the first time in North America. Juniper Research estimates that the robocall mitigation framework in the US-STIR/SHAKEN-has reduced the year-on-year growth of fraudulent losses to illegal robocalling in the region by 85% between 20. Good news for consumers, businesses and the communication service providers (CSPs) that serve them: Illegal robocalls are trending down. Other useful features of FontForge include support for automatic saving of changes when working with letters, extraction of fonts from PDF documents and the ability to create presets for Mac fonts. Once you've finished working on all the letters of the alphabet, you'll be able to save the finished font by giving it a name, specifying the "family", version and range of Unicode. It's creating some kind of blank space for you to mold a letter later on. Starting to work on a new project in any case you will have to resort to the function "generate". Generally speaking, you will not be able to create a certain symbol from scratch in FontForge. Convenient curve management, distance measurement and scaling tools are also available. In the editor you will find a lot of tools for drawing, transforming, rounding, adding notches, as well as copying individual elements or parameters of the letter (height, width, etc.). In general, the program is perfect for creating new fonts based on existing ones. By clicking on any letter, you can change it at will with or without symmetry. To import ready-made fonts, the program offers a convenient file browser, which allows you to open several files simultaneously and select separate tabs for them in the local editor.Īfter importing the file, FontForge will display a convenient panel with examples of lowercase and capital letters. Leave the Append a FONTLOG entry and Prepend timestamp options unchecked.FontForge is a program for creating, editing and converting fonts that supports TrueType, OpenType, PostScript, CFF, SVG, CID and BDF formats. In the eventuality that you are a creative professional, then there is a chance that the thought of enhancing the typography has crossed your mind for certain projects. Fontforge is an open source font editor running under Linux and Windows/Cygwin. Select the PS Glyph Names, OpenType, and Dummy DSIG options in the window that pops up, and deselect everything else. For the latest version see Reducing Font Size Removing Bitmap from Font File. Some TrueType files embed a bitmap version of the font. Mac OS X: Double-click the font file > 'Install font' button. When Fontforge opens such a file, it will ask whether to keep the bitmap or not. How to install a font (details in the Help section) Extract the files you have downloaded, then: Windows 10/8/7/Vista: Right-click on the font files > 'Install'. FontForge is a lightweight program that bundles a wide range of advanced options for creating and editing font types and can be a great tool for anyone looking to personalize fonts, especially the ones with some background in such apps.Ĭlick the Generate button, and FontForge will build your font file. To open a FontForge file, you’ll need to go to File > Open > YourFont. While the setup is a straightforward and uneventful operation, one nuisance is that you need to have a font file readily available to access the application. You can use the file browser to locate and open a font type from the hard drive, but this can be a deal breaker if you are simply interested in creating a new font. Nevertheless, you can create new fonts, an operation that entails drawing each glyph until you form a complete alphabet, number system and symbols. This describes two different types of fonts, a SplineFont (which is a postscript or truetype font) and a BDFFont (bitmap font, essentially a bdf file). The good news is that the program puts several drawing tools at your disposal, such as curve points, distance measurement, hand scrolling and magnification. The result is unlikely ever to be of the quality of the commercially-produced Type 1 font, but theres always the FontForge font editor to tidy things. Not to mention that you can manage multiple layers (e.g. Download FontForge Home downloads Download FontForge FontForge releases are available for Windows, Mac and GNU+Linux. Includes numerous features for editing fontsĪlthough it may not be the friendliest tool out there if you want to create new fonts, it is truly remarkable when it comes to editing other fonts. To put it simply, every element related to fonts can be edited, including the PS name, size, Unicode ranges, so on and so forth. It is worth mentioning that the app comes with a search function that enables you to search for any feature available within the app by color, wildcard, script, transform layers, unlink references, merge fonts, enable auto hints, execute the script, generate a Mac family, as well as edit resources, just to name a few. A handy application for anyone who wants to manage and create fontsĪll in all, FontForge provides you with the required tools for creating and editing font types, as long as they are patient enough to comprehend them. Keep in mind that the program may appear quite complicated and rough, especially if you didn't use similar apps before. In fact, one downside would be the seemingly cluttered interface and numerous advanced settings make this program pretty hard to learn, even with the included help manual.

SunVox is a small, fast and powerful modular synthesizer with pattern-based sequencer (tracker). Some of them have dual mounting holes, the back plate will have both regular three hole G-mounting, and standard humbucking spaced holes, but if you want to use the humbucker holes, you’ll have to open up the pup opening in the Oscar, it’s a tight ordeal, because you don’t want a straight route the shape of the plate on the guitars top. This guitar sounds golden (but is a boat anchor), which is why I also installed a upper horn strap peg (reinforced inside with a 1” dowel Rod). I did add a small rectangle of black foam under each pickup to keep them from rocking, it also keeps it level in the mount. This is what I did on my Epi Dot Studio, which out Gretsch’d a Gretsch for me last year. This will allow you to return the guitar to stock with just a trim ring/pickup change, and no drilling. You can cut off the corners of the G-mount with a coping saw so the plate will fit inside a standard HB opening (again, evenly on both sides), it will require you use a utility knife/razor blade/plastic deburring tool to open up the existing HB trim ring to work (or if you have spares in your parts bin). If the plate is drilled for humbucker mount, and you know beyond the shadow of a doubt that you will never use these in a traditional G-mount again. You will have to fill/redrill the pup ring holes on the Oscar top, to center them properly. If you go HB ring, and are looking for them online, make sure you measure the thickness of your existing rings on the Oscar (which are likely thicker than the G ones). If you’re going to put the whole assembly (original trim ring, and all), just route accordingly (making sure to center the pup, and not just trim one side, or your mistake will look mighty obvious). If you don’t do that, you’ll end up with a bigger opening in the top than even a G-sized humbucker ring will *edit* not *edit* hide. you want just enough clearance to get the plate under the lip of the top, and then dig out the block inside to allow adjustment.

This section describes two general models for digital signature schemes. §1.6 provides a brief introduction to the basic ideas behind digital signatures, and §1.8.3 shows how these signatures can be realized through reversible public-key encryption techniques. Further notes, including subtle points on schemes documented in the chapter and variants (e.g., designated confirmer signatures, convertible undeniable signatures, group signatures, and electronic cash) may be found in §11.9.ġ1.2 A framework for digital signature mechanisms Variations on the basic concept of digital signatures, including blind, undeniable, and fail-stop signatures, are discussed in §11.8. §11.7 describes arbitrated digital signatures and the ESIGN signature scheme. One-time signature schemes, many of which arise from symmetric-key cryptography, are considered in §11.6. Techniques based on the intractability of the discrete logarithm problem, such as the Digital Signature Algorithm (DSA) and ElGamal schemes, are the topic of §11.5. §11.4 looks at methods which arise from identification protocols described in Chapter 10. Standards which have been adopted to implement RSA and related signature schemes are also considered here. §11.3 provides an indepth discussion of the RSA signature scheme, as well as closely related techniques. It is more abstract than succeeding sections. §11.2 provides terminology used throughout the chapter, and describes a framework for digital signatures that permits a useful classification of the various schemes. This chapter is an account of many of the results obtained to date, with emphasis placed on those developments which are practical. Some offer significant advantages in terms of functionality and implementation. Subsequent research has resulted in many alternative digital signature techniques. The first method discovered was the RSA signature scheme, which remains today one of the most practical and versatile techniques available. The concept and utility of a digital signature was recognized several years before any practical realization was available. Certification is a means for a trusted third party (TTP) to bind the identity of a user to a public key, so that at some later time, other entities can authenticate a public key without assistance from a trusted third party. One of the most significant applications of digital signatures is the certification of public keys in large networks. Signatures must be verifiable if a dispute arises as to whether a party signed a document (caused by either a lying signer trying to repudiate a signature it did create, or a fraudulent claimant), an unbiased third party should be able to resolve the matter equitably, without requiring access to the signer’s secret information (private key).ĭigital signatures have many applications in information security, including authentication, data integrity, and non-repudiation. A digital signature of a message is a number dependent on some secret known only to the signer, and, additionally, on the content of the message being signed. This chapter considers techniques designed to provide the digital counterpart to a handwritten signature. Signatures with additional functionality. Ī framework for digital signature mechanisms.

In this example, we will use a TLS/SSL certificate for the client certificate, export its public key and then export the CA certificates from the public key to get the trusted client CA certificates. Trusted client CA certificate is required to allow client authentication on Application Gateway. PrerequisitesĪn existing client certificate is required to generate the trusted client CA certificate chain. In this article, you'll learn how to export a trusted client CA certificate chain that you can use in your client authentication configuration on your gateway. If you have multiple certificate chains, you'll need to create the chains separately and upload them as different files on the Application Gateway. In order to configure mutual authentication with the client, or client authentication, Application Gateway requires a trusted client CA certificate chain to be uploaded to the gateway. |
