Use Certificates for encrypting and decrypting email.
Why use certificates for email encryption?
SecureLine PKI supports both PGP and S/MIME for message encrypting and decryption and can determine what to use on a per-recipient basis. E.g. you can easily send one message to multiple recipients and have some use PGP, others use S/MIME, and others use other encryption modes, automatically.
