View source for HAS-V

'''HAS-V''' is a [[Cryptographic hash function|cryptographic hash function]] with a variable output length. HAS-V is a hash function based on a [[Block cipher|block cipher]]. The hash function can produce hash values with lengths from 16 to 40 bytes.

==Specifications==
Digest Size: 128-320 [[Bit|bit]]s
Max message length: <2<sup>64</sup> bits
Compression Function: 1024-bit message block, 320-bit chaining variable

The hash function was developed by Nan Kyoung Park, Joon Ho Hwang and Pil Joong Lee,<ref>Designers - [http://www.users.zetnet.co.uk/hopwood/crypto/scan/md.html Standard Cryptographic Algorithm Naming.]</ref> and was released in 2000.
