密码学

A primary motivation for cryptographic hash functions is that they serve as compact representative images of input messages, which they can uniquely identify. For example, the MD5 hash code "72c067b50c90837c95186d019f686700" can be looked on as the "fingerprint" to represent this thesis title uniquely.

密码学杂凑函数也称Hash函数、哈希函数或单向散列函数，它可以将任意长度的消息压缩到固定长度的杂凑值。
