Geralt is a modern cryptographic library for .NET 8+ based on libsodium and inspired by Monocypher.

  • Simple: an easy-to-learn API with descriptive naming. Only one algorithm for each task is provided when possible.
  • Modern: the latest and greatest cryptographic algorithms, such as AEGIS-128L/AEGIS-256, (X)ChaCha20-Poly1305, BLAKE2b, Argon2id, X25519, and Ed25519.
  • Secure: libsodium was audited in 2017 and is the library of choice for lots of projects and even large companies.
  • Fast: libsodium is faster than many other cryptographic libraries. Furthermore, Geralt uses Span<T> buffers to avoid memory allocations.
