Detailed Description

Struct containing the parameters required for generating an EdDSA digital signature.

Field Documentation

curve

const ECCParams_CurveParams* EDDSA_OperationSign::curve

A pointer to the elliptic curve parameters

myPrivateKey

const CryptoKey* EDDSA_OperationSign::myPrivateKey

A pointer to the randomly generated private key "k" in little endian. Must be 32 bytes for Ed25519.

myPublicKey

const CryptoKey* EDDSA_OperationSign::myPublicKey

A pointer public EdDSA key A = s*B in compressed public key format. Must be 32 bytes for Ed25519.

preHashedMessage

const uint8_t* EDDSA_OperationSign::preHashedMessage

A pointer to the (prehashed) message in little endian. In the PureEdDSA scheme, the prehash function is the identity, PH(M) = M.

preHashedMessageLength

size_t EDDSA_OperationSign::preHashedMessageLength

Length of the message buffer in bytes.

R

uint8_t* EDDSA_OperationSign::R

Signature component R = r*B in little endian. Must be 32 bytes for Ed25519.

S

uint8_t* EDDSA_OperationSign::S

Signature component S = r + x*s mod n in little endian. Must be 32 bytes for Ed25519.
