Questions about official cryptographic standards and their implementation.

stream-cipher× 53
an encryption algorithm which encrypts arbitrary length plain text, using a (fixed length) key. Some stream ciphers generate a key stream from only the key, which is then XOR-combin…

substitution-cipher× 21
an encryption algorithm which works by replacing plaintext units with corresponding ciphertext units, following some rule depending on the key.

symmetric× 61
Symmetric cryptosystems assume two communicating entities share a pre-established secret key.

xml-encryption× 2
Encryption of data represented in XML according to the W3C Specification.

xor× 18
one of the basic operations on bits and bit-sequences. It is a building block of many cryptographic primitives (and some higher-level algorithms, like modes of operations).

zero-knowledge-proofs× 32
an interactive method for one party to prove to another that a statement is true, without revealing anything other than the veracity of the statement.
