Feature #6943
pstore in FIPS mode
Description
Is there any chance to make PStore compatible with FIPS mode? PStore is using MD5 for data checksum, but MD5 is unsupported algorithm in FIPS mode unfortunately. It would be easy to use different hash algorithm, but I am afraid that backward compatibility would be lost. Thank you.

Ping? Any chance to change the hashing algorithm?

lib/pstore.rb uses digest/md5, and it uses own implementation (ext/digest/md5/md5.c) if there's no openssl
or it doesn't support MD5, it extconf.rb works correctly.

Using internal implementation is just hiding the issue. I don't think this would be acceptable solution for FIPS certification, what would be the point then? It is quite easy to generate colliding hashes these days. It might not be that critical for PStore though ...

Seems nothing to block, since md5 seems used just to see if the data is modified.
