md5chk is a tool for creating MD5 sums. It was designed so that its output would be easy to use with command line shells. It guarantees that the MD5 sum is always "clean" of characters that would be misinterpreted by the shell and that special characters in the file names are always properly escaped.
|Operating Systems||POSIX Linux Unix|
|Implementation||C Unix Shell bash|
Release Notes: This release added a -p option for sending a prefix to the MD5 algorithm before the rest of the data is sent to it. This thwarts MD5 dictionary attacks.
