Noun
plaintext (plural plaintexts)
(cryptography, computing) Alternative spelling of plain text
A CHK is a SHA-256 hash of a document (after encryption, which itself depends on the hash of the plaintext) and thus a node can check that the document returned is correct by hashing it and checking the digest against the key. Source: Internet
A separate notion was the use of a one-time pad of letters to encode plaintext directly as in the example below. Source: Internet
Because the key material must be transported from one endpoint to another, and persist until the message is sent or received, it can be more vulnerable to forensic recovery than the transient plaintext it protects (see data remanence ). Source: Internet
A set of reverse rounds are applied to transform ciphertext back into the original plaintext using the same encryption key. Source: Internet
A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). Source: Internet
As with any stream cipher, these can be used for encryption by combining it with the plaintext using bit-wise exclusive-or ; decryption is performed the same way (since exclusive-or with given data is an involution ). Source: Internet
