Possible disadvantages of TextSecure

• Limited Platform Support
  TextSecure might not be available on all devices or platforms, limiting its accessibility for some users who are not using supported systems.
• Potential Performance Issues
  Some users may experience performance issues or glitches, especially on older devices, due to the complexity of encryption operations.

  Like many encrypted messaging apps, TextSecure requires a stable internet connection to operate effectively, which can be a limitation in areas with poor connectivity.

Email + PGP features and specs

• Enhanced Security
  PGP encryption provides a high level of security for email communications, making it difficult for unauthorized parties to intercept and read messages.

Possible disadvantages of Email + PGP

• Complex Setup
  Setting up PGP can be complex for new users, involving several steps and a learning curve related to keys and encryption processes.
• Key Management
  Users must manage their own encryption keys, which can be cumbersome and requires understanding how to safely store and distribute keys.
• Limited Compatibility
  Not all email providers and clients support PGP natively, potentially limiting its use in standard email applications.
• Usability Concerns
  The process of encrypting and decrypting emails can add extra steps to communication, potentially discouraging regular use due to increased complexity.
