  2. Base32 - Wikipedia

    en.wikipedia.org/wiki/Base32

    Base32 is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).Since base32 is not very widely adopted, the question of notation—which characters to use to represent the 32 digits—is not as settled as in the case of more well-known numeral systems (such as hexadecimal), though RFCs and ...

  3. Hexadecimal - Wikipedia

    en.wikipedia.org/wiki/Hexadecimal

    Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.

  4. Beaufort cipher - Wikipedia

    en.wikipedia.org/wiki/Beaufort_cipher

    To decrypt, the process is reversed. Unlike the otherwise very similar Vigenère cipher, the Beaufort cipher is a reciprocal cipher, that is, decryption and encryption algorithms are the same. This obviously reduces errors in handling the table which makes it useful for encrypting larger volumes of messages by hand, for example in the manual ...

  5. VeraCrypt - Wikipedia

    en.wikipedia.org/wiki/VeraCrypt

    VeraCrypt's block cipher mode of operation is XTS. [13] It generates the header key and the secondary header key (XTS mode) using PBKDF2 with a 512- bit salt . By default they go through 200,000 to 500,000 iterations, depending on the underlying hash function used and whether it is system or non-system encryption. [ 14 ]

  6. Ciphertext - Wikipedia

    en.wikipedia.org/wiki/Ciphertext

    Symmetric key algorithms can either be block ciphers or stream ciphers. Block ciphers operate on fixed-length groups of bits, called blocks, with an unvarying transformation. Stream ciphers encrypt plaintext digits one at a time on a continuous stream of data, with the transformation of successive digits varying during the encryption process.

  7. SHA-1 - Wikipedia

    en.wikipedia.org/wiki/SHA-1

    [16] [2] However, SHA-1 is still secure for HMAC. [ 17 ] Microsoft has discontinued SHA-1 code signing support for Windows Update on August 3, 2020, [ 18 ] which also effectively ended the update servers for versions of Windows that have not been updated to SHA-2, such as Windows 2000 up to Vista , as well as Windows Server versions from ...

  8. ICE (cipher) - Wikipedia

    en.wikipedia.org/wiki/ICE_(cipher)

    ICE is a 16-round Feistel network.Each round uses a 3232 bit F function, which uses 60 bits of key material. The structure of the F function is somewhat similar to DES: The input is expanded by taking overlapping fields, the expanded input is XORed with a key, and the result is fed to a number of reducing S-boxes which undo the expansion.

  9. Lucifer (cipher) - Wikipedia

    en.wikipedia.org/wiki/Lucifer_(cipher)

    The key selects which S-boxes are used. The patent describes the execution of the cipher operating on 24 bits at a time, and also a sequential version operating on 8 bits at a time. Another variant by John L. Smith from the same year [3] uses a 64-bit key operating on a 32-bit block, using one addition mod 4 and a singular 4-bit S-box. The ...
