Hello, i m using the VPN solution openVPN, and OPENVPN provides quite many cipher algorithm,the default one is blowfish. here is the list: DES-CBC 64 bit default key (fixed) RC2-CBC 128 bit default key (variable) DES-EDE-CBC 128 bit default key (fixed) DES-EDE3-CBC 192 bit default key (fixed) DESX-CBC 192 bit default key (fixed) BF-CBC 128 bit default key (variable) RC2-40-CBC 40 bit default key (variable) CAST5-CBC 128 bit default key (variable) RC2-64-CBC 64 bit default key (variable) AES-128-CBC 128 bit default key (fixed) AES-192-CBC 192 bit default key (fixed) AES-256-CBC 256 bit default key (fixed) CBC mode is recommended but it seems they are all CBC anyway. Which one do you recommand me? i want an efficient and robust cipher algorithm. best regards sebastien _________________________________________________________________ MSN Messenger : discutez en direct avec vos amis ! http://www.msn.fr/msger/default.asp
