Hi ! Everything works fine, I crypt emails from Linux and I decrypt them under outlook/outlook express (PC) and netscape (PC/MAC/Xwindow). So I was very happy this morning ! But impossible to find where is the certificat menu in outlook express 5.02 for Mac ... (nothing in help pages about that, neither -as usual- on micosoft web site) ... (same problem with IE4.5 and certificats bank : impossible to find it) So if someone use Outlook express 5.2 for Mac, please tell me where can I import my .p12 file ! (stupid question, but I really look in each menu/sub menu and tabs ... ) PS : Thanks Erwann for your answer about DES and DES3 ... ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
