Encryption and signing

S/MIME and OpenPGP: keys, certificates, what happens when you sign, encrypt or receive encrypted mail.

  1. S/MIME

    Import your certificate, collect your contacts' certificates, and sign, encrypt and verify mail with S/MIME.

  2. OpenPGP

    Create or import your OpenPGP key, add your correspondents' public keys, and see which algorithms FOLD accepts.

  3. Fortress Mode

    Encrypt the local mail store of an account with a passphrase that FOLD never stores.
