OpenSSL 3.0 deprecated functions MD5_Init SHA1_Init

[kwizart]

Only a deprecation warning at this time, but since looking into it. There is a need to adapt theses.

I assume these need to be converted to use the openssl higher level APIs.

I'm not sure when I might get a chance to transition these. PRs welcome.
