  2. Cipher - Wikipedia

    en.wikipedia.org/wiki/Cipher

    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. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as ...

  3. Cryptography - Wikipedia

    en.wikipedia.org/wiki/Cryptography

    Cryptography. Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized : kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [ 1] ), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [ 2]

  4. Caesar cipher - Wikipedia

    en.wikipedia.org/wiki/Caesar_cipher

    In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. 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.

  5. Common Scrambling Algorithm - Wikipedia

    en.wikipedia.org/wiki/Common_Scrambling_Algorithm

    The Common Scrambling Algorithm ( CSA) is the encryption algorithm used in the DVB digital television broadcasting for encrypting video streams . CSA was specified by ETSI and adopted by the DVB consortium in May 1994. It is being succeeded by CSA3, [1] based on a combination of 128-bit AES and a confidential block cipher, XRC.

    en.wikipedia.org/wiki/Comparison_of_cryptography...

    Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5. HMAC- SHA1.

  7. Book cipher - Wikipedia

    en.wikipedia.org/wiki/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 . A simple version of such a cipher would use a specific book as the key, and would replace each word of the plaintext by a number that gives the position where that word occurs in that book.

  8. Symmetric-key algorithm - Wikipedia

    en.wikipedia.org/wiki/Symmetric-key_algorithm

    Symmetric-key algorithms[ a] are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. [ 1] The keys, in practice, represent a shared secret between two or more parties ...

  9. Vigenère cipher - Wikipedia

    en.wikipedia.org/wiki/Vigenère_cipher

    The Vigenère cipher ( French pronunciation: [viʒnɛːʁ]) is a method of encrypting alphabetic text where each letter of the plaintext is encoded with a different Caesar cipher, whose increment is determined by the corresponding letter of another text, the key . For example, if the plaintext is attacking tonight and the key is ...
