Constants ¶
const ( PrivKeyAminoName = "aphelion/PrivKeyEd25519" PubKeyAminoName = "aphelion/PubKeyEd25519" // Size of an Edwards25519 signature. Namely the size of a compressed // Edwards25519 point, and a field element. Both of which are 32 bytes. SignatureSize = 64 )
const PubKeyEd25519Size = 32
PubKeyEd25519Size is the number of bytes in an Ed25519 signature.

Types ¶
type PrivKeyEd25519 ¶
type PrivKeyEd25519 [64]byte
PrivKeyEd25519 implements crypto.PrivKey.
func GenPrivKey ¶
func GenPrivKey() PrivKeyEd25519
GenPrivKey generates a new ed25519 private key. It uses OS randomness in conjunction with the current global random seed in aphelion/libs/common to generate the private key.
func GenPrivKeyFromSecret ¶
func GenPrivKeyFromSecret(secret []byte) PrivKeyEd25519
GenPrivKeyFromSecret hashes the secret with SHA2, and uses that 32 byte output to create the private key. NOTE: secret should be the output of a KDF like bcrypt, if it's derived from user input.
func (PrivKeyEd25519) Bytes ¶
func (privKey PrivKeyEd25519) Bytes() []byte
Bytes marshals the privkey using amino encoding.
func (PrivKeyEd25519) Equals ¶
func (privKey PrivKeyEd25519) Equals(other crypto.PrivKey) bool
Equals - you probably don't need to use this. Runs in constant time based on length of the keys.
func (PrivKeyEd25519) PubKey ¶
func (privKey PrivKeyEd25519) PubKey() crypto.PubKey
PubKey gets the corresponding public key from the private key.
func (PrivKeyEd25519) Sign ¶
func (privKey PrivKeyEd25519) Sign(msg []byte) ([]byte, error)
Sign produces a signature on the provided message. This assumes the privkey is wellformed in the golang format. The first 32 bytes should be random, corresponding to the normal ed25519 private key. The latter 32 bytes should be the compressed public key. If these conditions aren't met, Sign will panic or produce an incorrect signature.
type PubKeyEd25519 ¶
type PubKeyEd25519 [PubKeyEd25519Size]byte
PubKeyEd25519 implements crypto.PubKey for the Ed25519 signature scheme.
func (PubKeyEd25519) Address ¶
func (pubKey PubKeyEd25519) Address() crypto.Address
Address is the SHA256-20 of the raw pubkey bytes.
func (PubKeyEd25519) Bytes ¶
func (pubKey PubKeyEd25519) Bytes() []byte
Bytes marshals the PubKey using amino encoding.
func (PubKeyEd25519) Equals ¶
func (pubKey PubKeyEd25519) Equals(other crypto.PubKey) bool
nolint: golint
func (PubKeyEd25519) String ¶
func (pubKey PubKeyEd25519) String() string
func (PubKeyEd25519) VerifyBytes ¶
func (pubKey PubKeyEd25519) VerifyBytes(msg []byte, sig []byte) bool
