- PGP is outdated and has numerous security flaws, making it unsuitable for modern cryptographic needs.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- PGP lacks modern cryptographic features like forward secrecy and authenticated encryption, relying instead on outdated and insecure primitives.
- The user experience with PGP is notoriously poor, making it difficult for even technical users to set up and use correctly.
- PGP encourages the use of long-term keys, which increases the risk of key compromise and reduces security.
- PGP's key distribution mechanisms, such as the web of trust and keyservers, are ineffective and often leak metadata.
- Alternatives to PGP exist for various use cases, such as Signal for secure messaging, Magic Wormhole for file transfers, and Signify/Minisign for package signing.
- Encrypting email with PGP is discouraged due to inherent insecurities in email itself and the additional risks posed by PGP's flaws.
- Modern cryptographic tools like libsodium and age provide better security and usability than PGP for application data and file encryption.
- The GnuPG implementation of PGP has a history of vulnerabilities and is not considered a secure or reliable codebase.
