Bifrost.Security

Bifrost.Security is a cryptography library written in C#

Currently it supports:

  • Ed25519 signatures
  • Key-exchange using either Curve25519 (montgomery form) or Ed25519 public keys
  • Hashing using SHA-512

Most functions come in two variants:

  • An easy to use variant, where inputs are complete byte arrays and results are returned in newly allocated arrays.
  • An advanced variant which uses ArraySegment<byte> to work on slices of the passed in arrays. This can be used to avoid unnecessary allocations and copies.

Ed25519 (Key-exchange and signatures)

Ed25519 is a public key crypto system with a 128 bit security level. It is based on the 255 bit elliptic curve Curve25519 using Edwards coordinates.

Data structures

  • Public Keys are 32 byte values. All possible values of this size a valid.

  • Private Keys take two forms:

    • A 32 byte seeds which allow arbitrary values. This is the form that should be generated and stored.
    • A 64 byte expanded form. This forms is used internally to improve performance

  • Signatures are 64 byte values

To generate a keypair first obtain a 32 byte random value, the privateKeySeed from a cryptographic random number generator, such as RNGCryptoService.

Then call KeyPairFromSeed on it to get the publicKey and the expandedPrivateKey.
