We needed to choose a library to hash the users passwords in the database.
- Simple API for Password Hashing: libsodium provides a straightforward API, making password hashing simple to implement and maintain.
- Automatic Salting: With libsodium, salting is handled automatically, adding a unique, cryptographic salt to each hash without additional code complexity.
- Secure Against Attacks: Argon2 is designed to be memory-hard, providing a robust defense against brute-force and side-channel attacks.
- Future-Proof Security: Argon2 has been widely recognized as one of the most secure hashing algorithms, making it a reliable choice for applications that require long-term security.
- Windows and Linux Support: libsodium is cross-platform, compatible with both Windows and Linux, ensuring consistent behavior regardless of the operating system.
- Easy Installation with vcpkg: Installing libsodium through vcpkg (Visual Studio C++ Package Manager) simplifies setup and configuration, especially for C++ applications.
- Optimized for Modern Processors: libsodium offers high-performance implementations of cryptographic algorithms, including hardware-optimized support where available.
- Efficient Memory Use with Argon2: By adjusting parameters, developers can balance memory and processing time, optimizing for the specific performance needs of their application.
- Encryption and Decryption: In addition to hashing, libsodium supports encryption, making it an all-in-one library for multiple cryptographic needs.
- Secure Random Number Generation: libsodium’s secure random number generator is useful for other security aspects, such as generating unique user IDs or session tokens.
| Feature | libsodium | OpenSSL | bcrypt |
|---|---|---|---|
| Hashing Algorithm | Argon2 (modern) | SHA256, SHA512, etc. | bcrypt |
| Salting | Automatic | Manual | Automatic |
| Ease of Use | Very Easy | Moderate | Moderate |
| Installation with vcpkg | Yes | Limited | No |
| Cross-Platform | Yes (Win/Linux) | Yes | Yes |
| Security Level | High (memory-hard) | High (memory-hard) | Moderate |
libsodium is a powerful choice for secure password hashing due to its simplicity, cross-platform support, and use of Argon2. With easy installation through vcpkg and a straightforward API that includes automatic salting, libsodium provides a highly secure, developer-friendly solution for password hashing that works seamlessly on Windows and Linux.
