Difference Between PGP and S/MIME
In this post, we will understand the difference between PGH and S/MIME −
PGP
It has been designed to process plain text.
It is not expensive in comparison to S/MIME.
It can be used personally as well as at offices.
It is less efficient in comparison to S/MIME.
It depends on the key exchange made by the user.
It is less convenient in comparison to S/MIME.
It contains 4096 public keys.
It is considered as the standard for strong encryption.
It can be used in VPNs.
It uses Diffie-Hellman digital signature.
S/MIME
It has been designed to process email and multimedia files.
It is relatively expensive.
It is used in industrial purposes.
It is more efficient in comparison to PGP.
It depends on a hierarchical valid certificate for key exchange.
It is easy/convenient to use, since it uses secure transformation in all its applications.
It contains 1024 public keys.
It is also considered as the standard for strong encryption but has certain cons.
It is used with email services, not VPNs.
It uses Elgamal digital signature.
