It seems your code is replicating parts of libssl - which seems like a
strange (and possibly dangerous) thing to do!

You really don't need to access these things. They're just cached
references to the value returned by EVP_get_digestbyname("ssl3-md5") and
EVP_get_digestbyname("ssl3-sha1"). So you can call those functions
directly anyway.
