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

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