Exempel på hur man kan använda CIPHER i en mening

• Blowfish is a symmetric-key block cipher, designed in 1993 by Bruce Schneier and included in many cipher suites and encryption products.
• In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called blocks.
• In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
• In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher).
• Colossus was a set of computers developed by British codebreakers in the years 1943–1945 to help in the cryptanalysis of the Lorenz cipher.
• The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication.
• The letters of the alphabets involved have standard numerical values, but a word can yield several values if a cipher is used.
• In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991.
• In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher.
• The film follows a World War II German submarine boarded by American submariners to capture her Enigma cipher machine.
• In the history of cryptography, Typex (alternatively, Type X or TypeX) machines were British cipher machines used from 1937.
• A5/1a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard.
• Due to the fact that there is only one way to perform this, the Atbash cipher provides no communications security, as it lacks any sort of key.
• In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.
• In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters (transposition) without changing the characters themselves.
• ROT13 (Rotate13, "rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the Latin alphabet.
• In cryptography, Triple DES (3DES or TDES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.
• It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
• The operation of the keystream generator in A5/1, an LFSR-based stream cipher used to encrypt mobile phone conversations.
• During the Second World War, he made a brilliant and fundamental advance in cryptanalysis of the Lorenz cipher, a major Nazi German cipher system which was used for top-secret communications within the Wehrmacht High Command.
