Detailed Description

Hold a 16-byte MD5 hash from a stream of data. SSL_Hash_MD5 NOT known to be reversible, but possible to brute force guess. This should ideally be instance salted so it cannot be compared with other known hashes.

Note
In theory this is not as good as SHA1. In 2015 allegations of cracking for MD5? (via SLOTH attack)
