WebCryptography is a discipline which concerns itself with communication secrecy. Coded mes- sages have long been used by businesses, governments and the military, and for obvious reasons. If you want to send a message to a friend or partner, you do not want it to under- stoodby everyone who intercepts that message.

WebA key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key … In cryptography, key size, key length, or key space refer to the number of bits in a key used by a cryptographic algorithm (such as a cipher). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all … See more Keys are used to control the operation of a cipher so that only the correct key can convert encrypted text (ciphertext) to plaintext. All commonly-used ciphers are based on publicly known algorithms or are open source and … See more Even if a symmetric cipher is currently unbreakable by exploiting structural weaknesses in its algorithm, it may be possible to run … See more The effectiveness of public key cryptosystems depends on the intractability (computational and theoretical) of certain mathematical problems such as integer factorization. These problems are time-consuming to solve, but usually … See more Encryption systems are often grouped into families. Common families include symmetric systems (e.g. AES) and asymmetric systems (e.g. RSA and Elliptic-curve_cryptography). They may be grouped according to the central algorithm used (e.g. See more IBM's Lucifer cipher was selected in 1974 as the base for what would become the Data Encryption Standard.
