Detailed Description

template<typename T>
struct fizz::Sha< T >

Hash implementation using OpenSSL.

The template struct requires the following parameters:

• HashLen: length of the hash digest
• HashEngine: function returning EVP_MD* to use
• BlankHash: ByteRange containing the digest of a hash of empty input
