The SHA-1, produces a 160-bit message digest for a given data
24
stream. It should take about 2**n steps to find a message with the
25
same digest as a given message and 2**(n/2) to find any two
26
messages with the same digest, when n is the digest size in bits.
27
Therefore, this algorithm can serve as a means of providing a
28
"fingerprint" for a message.
