    en.wikipedia.org/wiki/Atbash

    Atbash (Hebrew: אתבש; also transliterated Atbaš) is a monoalphabetic substitution cipher originally used to encrypt the Hebrew alphabet. It can be modified for use with any known writing system with a standard collating order .

    SVT-AV1 – An AV1 encoder originally developed by Intel and Netflix, which is available as FOSS now. [5] SVT-AV1 is generally considered to be the most optimized and fastest free AV1 encoder, which is why it serves as the base for the development of new, free, general-purpose and production-ready implementations in the AOMedia Software ...

  4. Affine cipher - Wikipedia

    en.wikipedia.org/wiki/Affine_cipher

    The Atbash cipher uses a = −1. Considering the specific case of encrypting messages in English (i.e. m = 26), there are a total of 286 non-trivial affine ciphers, not counting the 26 trivial Caesar ciphers. This number comes from the fact there are 12 numbers that are coprime with 26 that are less than 26 (these are the possible values of a).

    The King James Bible, a highly available publication suitable for the book cipher.. A book cipher is a cipher in which each word or letter in the plaintext of a message is replaced by some code that locates it in another text, the key.

    The formatting of these ciphers generally includes a title, letter frequency, keyword indicators, and the encoder's nom de plume. [1] The predecessor to these ciphers stems from the Caesar Cipher around 100. The Aristocrat Cipher also used a transposition of letters to encrypt a message. [2]

  9. Fraunhofer FDK AAC - Wikipedia

    en.wikipedia.org/wiki/Fraunhofer_FDK_AAC

    The FDK AAC encoder employs a more aggressive default low-pass filter than is used in other codecs. Higher frequencies are removed so that more bits are available to better describe sounds of lower frequencies, improving the overall quality for most combinations of recordings and listeners.
