md5deep 4.2-1 (amd64 binary) in ubuntu quantal

 Md5deep is a set of tools to compute md5, sha-1, sha-256, tiger, whirlpool
 hashsums of arbitrary number of files recursively.
 .
 It can also compare those hashsums with a list of known hashes. The tools can
 display those that match the list or those that does not match. It can display
 a time estimation when processing large files. It can do piecewise hashing
 (hashing input files in arbitrary sized blocks).
