Pretty Good Privacy (PGP) is a cryptographic method developed by Phil Zimmerman in 1995 to ensure confidentiality and authentication in electronic mail systems. PGP uses various cryptographic algorithms and is compatible across different operating systems and email applications, providing users with security, flexibility, and ease of use. It is widely adopted due to its availability, effectiveness, and the independence from governmental control.

- 1. PRETTY GOOD PRIVACY (PGP) SECURITY FOR ELECTRONIC EMAIL
- 2. PGP There are two main schemes which are especially designed to provide confidentiality and authentication for electronic mail systems. These are: PGP(Pretty Good Privacy) S/MIME(Secure/Multipurpose Internet Mail Extension)
- 3. INTRODUCTION OF PGP • Developed by Phil Zimmerman in 1995. • Documentation and source code is freely available. • The package is independent of operating system and processor. PGP does not rely on the “establishment” and it’s popularity and use have grown extensively since 1995. PGP combines the best available cryptographic algorithms to achieve secure e-mail communication. It is assumed that all users are using public key cryptography and have generated a private/public key pair.
- 4. PRETTY GOOD PRIVACY PGP is a remarkable phenomenon that provides confidentiality, authentication, and compression for email and data storage. Its building blocks are made of the best available cryptographic algorithms: RSA, DSS, Diffie- Hellman. It is independent of operating system and processor. It has a small set of easy-to-use commands
- 6. WHY USE PGP? Security Flexibility It's Free! Worldwide Strength and Compatibility
- 8. Compatibility Confidentiality Digital signatures Web of trust Certificates Security quality
- 9. ADVANTAGES OF PGP Your valuable information is always protected, others cannot view it, and it cannot be stolen over the Internet No compatibility problems - works with any email application that you or your recipients are using Verification of the sender of information ensures you are not being spoofed by a third party Absolute assurity that the information you send or receive has not been modified in transit Your secure mail and text cannot be infiltrated by hackers or infected and mis-used by email attacks
- 10. DISADVANTAGES OF PGP ADMINISTERING CONFLICTING VERSIONS COMPATIBILITY ISSUES COMPLEXITY NO RECOVERY
- 11. CONCLUSIONS Because PGP is freely available via the Internet, and has a fully compatible low-cost commercial version it is now widely used. It has a wide range of applicability from corporations to individuals who wish to communicate worldwide securely over the Internet and other networks. It is not controlled by any government which makes it attractive to many.
