Hi, I have installed time ago the openssl-0.9.4 release. At that time, in the documents, I found that the SPKAC challenge was not actually used to check against replay attacks. Is this situation changed with the new openssl release? Which is exaclty the SPKAC format? Best wishes, Fabio. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
