If we are talking specifically about _cryptographic_ hash-value, I think
"fingerprint of a document", "messagedigest of a document" and
"cryptographic hash-value of a document" all mean the same. Normal,
non-cryptographic hash-values are also often used but their purpose is
different. Non-cryptographic hash-values do not serve as a "fingerprint".
Re: Differences between Fingerprint, MessageDigest and Hash-Value of a document?
Fingeprints often refer to a truncated short hash-- ie just a few of the
first digits of the hash converted to readable text. Ie, a quick check.
messagedigest suggests some very specific protocol. cyptographic hash refers
to any hash with a crypto strong hash function, and not necessarily part of
a protocol. Ie, a message digest includes a crypto hash, but a lot more
