Detailed Description

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

Field Documentation

curve

const ECCParams_CurveParams* EDDSA_OperationVerify::curve

A pointer to the elliptic curve parameters

theirPublicKey

const CryptoKey* EDDSA_OperationVerify::theirPublicKey

A pointer to the signer's public EdDSA key A = s*B in compressed public key format. Must be 32 bytes for Ed25519 and a valid point on Ed25519.

preHashedMessage

const uint8_t* EDDSA_OperationVerify::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_OperationVerify::preHashedMessageLength

Length of the message buffer in bytes.

R

const uint8_t* EDDSA_OperationVerify::R

Signature component R to verify in little endian. Must be 32 bytes for Ed25519.

S

const uint8_t* EDDSA_OperationVerify::S

Signature component S to verify in little endian. Must be 32 bytes for Ed25519.
