- PGP is outdated and has numerous deficiencies, making it unsuitable for modern cryptographic needs.
- PGP's design is overly complex, with a packet-based structure and multiple encoding methods that complicate implementation and use.
- PGP lacks modern cryptographic features like forward secrecy and uses outdated primitives, making it vulnerable to attacks.
- The user experience with PGP is poor, with difficult setup processes and cumbersome key management.
- PGP's key distribution mechanisms, such as the web of trust and key signing parties, are ineffective and impractical.
- PGP leaks metadata and lacks forward secrecy, compromising privacy and security.
- Alternatives to PGP are recommended for different use cases, such as Signal for messaging, Magic Wormhole for file transfers, and Signify/Minisign for package signing.
- Modern cryptographic tools like libsodium and age offer better security and usability than PGP.
