WebCryptographic hash functions play an important role in modern communication technology. The input to a hash function is a file or stream of any size and the output is a fixed-size digital representation of the file that is normally less than 1KB and serves as the fingerprint of the original file (often called the message digest). ... WebCryptographic hash functions have been designed with collision resistance as a major goal, but the current concentration on attacking cryptographic hash functions may result in a given cryptographic hash function providing less collision resistance than expected.
