KCDSA KCDSA (Korean Certificate-based Digital Signature Algorithm) is a digital signature algorithm created by a team led by the Korea Internet & Security Agency (KISA). It is an ElGamal signature scheme, ElGamal variant, similar to the Digital Signature ...

A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created b ...
algorithm. It is derived from
SHA-1, with assorted changes intended to increase its security. It produces a 160-bit output.
HAS-160 is used in the same way as SHA-1. First it divides input in blocks of 512 bits each and pads the final block. A digest function updates the intermediate hash value by processing the input blocks in turn.
The message digest algorithm consists of 80 rounds.
