HAS-V is a cryptographic hash function

Cryptographic hash function

A cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the hash value, such that an accidental or intentional change to the data will change the hash value...

 with a variable output length. HAS-V is a hash function based on a block cipher. The hash function can produce hash values with lengths from 16 to 40 bytes.

Specifications

Digest Size: 128-320 bits
Max message length: <2⁶⁴ 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, and was released in the year 2000.
