MD5 and SHA256 are secure (or, in the case of MD5, not so secure) hash algorithms, not encryption mechanisms.

Looking at this script, I'm not convinced that it relies on MD5 being a cryptophically secure hash function. It appears to me as if this script uses MD5 to simply detect innocent changes to a set of files as opposed to guarding against malicious attacks. I also found that sha256sum takes almost three times longer than md5sum. So, in the absence of security requirements, md5sum might actually be the better choice because it's faster.
