Yes, I can connect to servers requiring 128 bit.
> Have you tried decrypting messages using Outlook express? Outlook express can decrypt the message. > Will it decrypt encrypted mesages (not encrypted and signed)? No, the CAPI fails to decrypt messages that are encrypted only. It fails while decrypting. Windows 98 can perform the same decryption with no problems. > Can it handle encrypted and signed messages from other Windows machines?
