构造器详细资料

ECDSASignature

public ECDSASignature(BigInteger r,
                      BigInteger s)

Constructs a signature with the given components.

参数:

r - r

s - s

方法详细资料

isStrictlyCanonical

public static boolean isStrictlyCanonical(byte[] sig)

参数:

sig - Sig.

返回:

boolean value

checkIsCanonical

public static boolean checkIsCanonical(byte[] sig,
                                       boolean strict)

参数:

sig - sig.

strict - strict.

返回:

boolean value

encodeToDER

public byte[] encodeToDER()

DER is an international standard for serializing data structures which is widely used in cryptography. It's somewhat like protocol buffers but less convenient. This method returns a standard DER encoding of the signature, as recognized by OpenSSL and other libraries.

返回:

return value.

decodeFromDER

public static ECDSASignature decodeFromDER(byte[] bytes)

参数:

bytes - byte array.

返回:

ECDSASignature

derByteStream

protected ByteArrayOutputStream derByteStream()
                                       throws IOException

抛出:

IOException
