What is the difference between PGP and Smime?
PGP (Pretty Good Privacy) is an encryption protocol which provides cryptographic privacy and authentication. PGP can sign, encrypt and decrypt data. S/MIME (Secure/Multipurpose Internet Mail Extensions) is a protocol for sending signed and encrypted messages.
What does PGP and Smime in email security means?

What is an S MIME certificate?
An IdenTrust Secure Email (S/MIME) certificate is issued to your confirmed email address and is used to sign and encrypt email communications. A digitally signed email provides assurance to the recipient that the email originated from your verified email address and that it has not been originated by an attacker.

How does PGP provide authentication?
PGP provides authentication through the use of Digital Signature. It provides confidentiality through the use of symmetric block encryption. It provides compression by using the ZIP algorithm, and EMAIL compatibility using the radix-64 encoding scheme.
What are the disadvantages of PGP?
Disadvantages of PGP Encryption
- The Administration is difficult: The different versions of PGP complicate the administration.
- Compatibility issues: Both the sender and the receiver must have compatible versions of PGP.
- Complexity: PGP is a complex technique.
What’s the difference between PGP and S / MIME?
1. While it is designed to process email as well as many multimedia files. 2. PGP is less costly as compared to S/MIME. While S/MIME is comparatively expensive. 3. PGP is good for personal as well as office use. While it is good for industrial use. 4. PGP is less efficient than S/MIME. While it is more efficient than PGP.
