  2. Cryptography - Wikipedia

    en.wikipedia.org/wiki/Cryptography

    In colloquial use, the term "code" is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a more specific meaning: the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, "wallaby" replaces "attack at dawn"). A cypher, in contrast, is a ...

    en.wikipedia.org/wiki/Encryption

    The question of balancing the need for national security with the right to privacy has been debated for years, since encryption has become critical in today's digital society. The modern encryption debate [42] started around the '90s when US government tried to ban cryptography because, according to them, it would threaten national security ...

    en.wikipedia.org/wiki/Cryptographic_Message_Syntax

    The Cryptographic Message Syntax (CMS) is the IETF's standard for cryptographically protected messages. It can be used by cryptographic schemes and protocols to digitally sign, digest, authenticate or encrypt any form of digital data.

  7. Ciphertext - Wikipedia

    en.wikipedia.org/wiki/Ciphertext

    In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. [1] 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.

  9. Cryptanalysis - Wikipedia

    en.wikipedia.org/wiki/Cryptanalysis

    The security of two-key cryptography depends on mathematical questions in a way that single-key cryptography generally does not, and conversely links cryptanalysis to wider mathematical research in a new way. [citation needed] Asymmetric schemes are designed around the (conjectured) difficulty of solving various mathematical problems.
