Cryptographic primitives¶

PublicKey¶

Public key for public-key cryptography.

type PublicKey := | Curve25519PubKey ByteString;

deriving instance
PublicKeyEq : Eq PublicKey;

instance
PublicKeyOrd : Ord PublicKey :=
  mkOrd@{
    cmp := \{  := Equal};
  };

PrivateKey¶

PrivateKey¶

Private key for public-key cryptography.

type PrivateKey := | Curve25519PrivKey ByteString;

deriving instance
PrivateKeyEq : Eq PrivateKey;

instance
PrivateKeyOrd : Ord PrivateKey :=
  mkOrd@{
    cmp := \{  := Equal};
  };

SecretKey¶

Secret key for secret-key cryptography.

type SecretKey := | ChaCha20Key;

deriving instance
SecretKeyEq : Eq SecretKey;

deriving instance
SecretKeyOrd : Ord SecretKey;

Signature¶

Cryptographic signature.

type Signature := | Ed25519Signature ByteString;

Digest¶

Message digest. Output of a cryptographic hash function.

type Digest := | Blake3Digest ByteString;

hash¶

axiom hash {A} : A -> Digest;

deriving instance
DigestEq : Eq Digest;

instance
DigestOrd : Ord Digest :=
  mkOrd@{
    cmp := \{(Blake3Digest a) (Blake3Digest b) := Equal};
  };
