| | Digest::SHA2 - A variable-length one-way hash function (Site not responding. Last check: 2007-11-04) |
 | | Returns the digest size (in bits) of the hash output used; valid sizes are 256, 384, and 512 only. |
 | | Tiger, on the other hand, outputs 192 bits of digest, using 3 rounds; but for added security, can also use 4 rounds. |
 | | Before calculating another digest, reset() refreshes the hash state, and is, therefore, functionally equivalent to the new() method, except that no SHA-2 object is created. |
