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.
Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking. Decryption, the inverse of encryption, is the process of turning ciphertext into ...
AES-JS – portable JavaScript implementation of AES ECB and CTR modes. Forge – JavaScript implementations of AES in CBC, CTR, OFB, CFB, and GCM modes. asmCrypto – JavaScript implementation of popular cryptographic utilities with focus on performance. Supports CBC, CFB, CCM modes. pidCrypt – open source JavaScript library.
Esoteric programming language. An esoteric programming language (sometimes shortened to esolang) is a programming language designed to test the boundaries of computer programming language design, as a proof of concept, as software art, as a hacking interface to another language (particularly functional programming or procedural programming ...
RC5. 12-round RC5 (with 64-bit blocks) is susceptible to a differential attack using 2 44 chosen plaintexts. [ 1] In cryptography, RC5 is a symmetric-key block cipher notable for its simplicity. Designed by Ronald Rivest in 1994, [ 2] RC stands for "Rivest Cipher", or alternatively, "Ron's Code" (compare RC2 and RC4 ).
In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once. The following discussion assumes an elementary knowledge of matrices .
Block cipher. Appearance. In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called blocks. Block ciphers are the elementary building blocks of many cryptographic protocols. They are ubiquitous in the storage and exchange of data, where such data is secured and authenticated via encryption .
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 ...
