deuterium

deuterium - A modern cryptography library.

Yawning Angel (yawning at schwanenlied dot me)

A modern cryptography library for the D language, mostly written because I'm rage-quitting Go for my pet projects. This is being used primarily as an excuse to learn D well.

Supported Primitives:

• Cryptographic pseudo-random number generation
  • ChaCha20 based CSPRNG backed by OS entropy
  • Raw OS entropy
• ECC
  • X25519
• Message Authentication Codes
  • Poly1305
  • SipHash-2-4
• Stream ciphers
  • ChaCha20/XChaCha20

Planned Primitives:

• Block ciphers
  • AES
  • LIONESS
• ECC
  • Ed25519
  • (Maybe) X448
  • (Maybe) P-256
• Hash functions
  • BLAKE2
  • SHA3/SHAKE
• Stream ciphers
  • CTR-AES
• AE
  • NaCl style boxes (Poly1305/XChaCha20)
• AEAD
  • AEZv5
  • HS1-SIV
  • Poly1305ChaCha20
• PQ Primitives
  • NewHope-Simple
  • SPHINCS-256

Notes:

• Most people will probably be happier calling OpenSSL or libsodium.
• All primitives are written to be immune to timing side-channel attacks, though some utility functions are not.
• Correct, maintainable, fast in decreasing order of importance.
• Where possible, established implementations have been used as the basis of deuterium's implementations.
• Performance tuning is centered around the assumption that LDC is used when building for performance, and that a modern 64 bit Intel system with at least SSSE3 is the target. In particular the library makes liberal use of LDC's capability to inline LLVM IR.
• I do not have and therefore do not care about OSX or Windows.
• A modest amount of effort will be made to avoid breaking API changes without a major version bump, however API stability while the the project is in the 0.0.x series is not guaranteed.
