A message remains visible to all, but a cryptographic signature is added that can be verified by the recipient. However: S/MIME offers a signing functionin addition to encryption. In the end, you are forced to either convince all communication partners of the standard used or drive two tracks and use S/MIME and PGP variables. Although the operating principle of both methods is comparable, S/MIME and PGP are not compatible. To send someone an encrypted email, you need the recipient’s public key and your own private key. There is a private key and a public key (certificates at S / MIME). Both S/MIME and PGP are based on the same principle, so-called hybrid encryption. Neither S/MIME nor PGP have been cracked so far and are considered safe by experts. S/MIME (Secure/Multipurpose Internet Mail Extensions) has been around since 1995, PGP (Pretty Good Privacy) existed a little earlier, so since 1991. 1.1 Encryptionīasically, there are two common methods used for e-mail encryption: S/MIME and PGP. This ensures the integrity of the sender and excludes tampering. As a rule, simply a digital signature is sufficient. But you don’t have to encrypt every mail the same way. This e-mail can be read or modified on the way to the recipient. In principle, e-mails are sent in plain text.
