  2. Base64 - Wikipedia

    en.wikipedia.org/wiki/Base64

    Encoding an attachment as Base64 before sending, and then decoding when received, assures older SMTP servers will not interfere with the attachment. Base64 encoding causes an overhead of 33–37% relative to the size of the original binary data (33% by the encoding itself; up to 4% more by the inserted line breaks).

  3. Grok (JPEG 2000) - Wikipedia

    en.wikipedia.org/wiki/Grok_(JPEG_2000)

    Grok is a computer software library to encode and decode images in the JPEG 2000 format. It is designed for stability, high performance, and low memory usage. Grok is free and open-source software released under the GNU Affero General Public License (AGPL) version 3.

  4. Character encodings in HTML - Wikipedia

    en.wikipedia.org/wiki/Character_encodings_in_HTML

    The standard also defines a "replacement" decoder, which maps all content labelled as certain encodings to the replacement character ( ), refusing to process it at all. This is intended to prevent attacks (e.g. cross site scripting ) which may exploit a difference between the client and server in what encodings are supported in order to mask ...

  5. Percent-encoding - Wikipedia

    en.wikipedia.org/wiki/Percent-encoding

    URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding , it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource ...

  6. Encryption - Wikipedia

    en.wikipedia.org/wiki/Encryption

    In cryptography, encryption (more specifically, encoding encoding ) is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not ...

  7. UTF-8 - Wikipedia

    en.wikipedia.org/wiki/UTF-8

    UTF-8 is also the recommendation from the WHATWG for HTML and DOM specifications, and stating "UTF-8 encoding is the most appropriate encoding for interchange of Unicode" [4] and the Internet Mail Consortium recommends that all e‑mail programs be able to display and create mail using UTF-8.

  8. Seq2seq - Wikipedia

    en.wikipedia.org/wiki/Seq2seq

    Shannon's diagram of a general communications system, showing the process by which a message sent becomes the message received (possibly corrupted by noise). seq2seq is an approach to machine translation (or more generally, sequence transduction) with roots in information theory, where communication is understood as an encode-transmit-decode process, and machine translation can be studied as a ...

  9. Binary-to-text encoding - Wikipedia

    en.wikipedia.org/wiki/Binary-to-text_encoding

    A binary-to-text encoding is encoding of data in plain text. More precisely, it is an encoding of binary data in a sequence of printable characters . These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP ) or is not 8-bit clean .
