Thought to apply a better encryption mechanism.
MD5 and SHA256 are secure (or, in the case of MD5, not so secure) hash
algorithms, not encryption mechanisms.
Replace all occurance of md5sum to sha256sum .
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.
