Member Function Documentation

◆ secp256k1_ecdsa_verify()

static native int org.bitcoin.NativeSecp256k1.secp256k1_ecdsa_verify ( ByteBuffer byteBuff )

staticprivate

Parameters

byteBuff signature format is byte[32] data, native-endian int signatureLength, native-endian int pubkeyLength, byte[signatureLength] signature, byte[pubkeyLength] pub

Returns: 1 for valid signature, anything else for invalid

◆ verify()

static boolean org.bitcoin.NativeSecp256k1.verify	(	byte []	data,
		byte []	signature,
		byte []	pub
	)

inlinestatic

Verifies the given secp256k1 signature in native code. Calling when enabled == false is undefined (probably library not loaded)

Parameters

data	The data which was signed, must be exactly 32 bytes
signature	The signature
pub	The public key which did the signing
