方法详细资料

sign

public static SECP256K1.Signature sign(Bytes32 dataHash,
                                       SECP256K1.KeyPair keyPair)

verify

public static boolean verify(Bytes data,
                             SECP256K1.Signature signature,
                             SECP256K1.PublicKey pub)

Verifies the given ECDSA signature against the message bytes using the public key bytes.

When using native ECDSA verification, data must be 32 bytes, and no element may be larger than 520 bytes.

参数:

data - Hash of the data to verify.

signature - ASN.1 encoded signature.

pub - The public key bytes to use.

返回:

True if the verification is successful.

normaliseSignature

public static SECP256K1.Signature normaliseSignature(BigInteger nativeR,
                                                     BigInteger nativeS,
                                                     SECP256K1.PublicKey publicKey,
                                                     Bytes32 dataHash)

verify

public static boolean verify(Bytes data,
                             SECP256K1.Signature signature,
                             SECP256K1.PublicKey pub,
                             UnaryOperator<Bytes> preprocessor)

Verifies the given ECDSA signature using the public key bytes against the message bytes, previously passed through a preprocessor function, which is normally a hashing function.

参数:

data - The data to verify.

signature - ASN.1 encoded signature.

pub - The public key bytes to use.

preprocessor - The function to apply to the data before verifying the signature, normally a hashing function.

返回:

True if the verification is successful.

calculateECDHKeyAgreement

public static Bytes32 calculateECDHKeyAgreement(SECP256K1.PrivateKey privKey,
                                                SECP256K1.PublicKey theirPubKey)

Calculates an ECDH key agreement between the private and the public key.

参数:

privKey - The private key.

theirPubKey - The public key.

返回:

The agreed secret.
