About:
QCA (Qt Cryptographic Architecture) is a plugin-based cryptographic framework for Qt applications. It provides a unified API for various cryptographic operations like encryption, hashing, and digital signatures. Its main value proposition is simplifying the integration of robust security features into Qt-based software.
Key Features:
  • Plugin-based architecture for algorithm flexibility
  • Supports RSA, DSA, ECC, and symmetric ciphers
  • Provides secure handling of certificates and keys
  • Asynchronous API for non-blocking operations
Use Cases:
  • Implementing end-to-end encryption in Qt messaging apps
  • Securing data storage and file transfers
  • Validating digital signatures in desktop software
Alternatives:
  • OpenSSL – Lower-level C API, more complex to integrate with Qt
  • Libsodium – Focuses on modern, high-speed primitives but lacks Qt integration
