Cool. If you are concerned about "second pre-image" attacks on md5, use sha1, if you are also concerned about sha1, you can use sha2 fingerprints, but these are not enabled by default when you enable just the SSL algorithms. You have to enable "all" digest algorithms. See OpenSSL_add_all_digests(3). Despite all the recent progress, I am not aware of effective second pre-image attacks on either md5 or sha1. -- Viktor. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
