Method Detail

decodePublicKey

PublicKey decodePublicKey(byte[] me)

The public key is sent over the wire, thus the decoding of it needs special handling.

Parameters:

me - The byte array that contains the public key

Returns:

The decoded public key

decodePublicKey

PublicKey decodePublicKey(io.netty.buffer.ByteBuf buf)

encodePublicKey

void encodePublicKey(PublicKey publicKey,
                   io.netty.buffer.ByteBuf buf)

sign

SignatureCodec sign(PrivateKey private1,
                  ByteBuffer[] byteBuffers)
                    throws InvalidKeyException,
                           SignatureException,
                           IOException

Throws:

InvalidKeyException

SignatureException

IOException

verify

boolean verify(PublicKey public1,
             ByteBuffer[] byteBuffers,
             SignatureCodec signature)
               throws SignatureException,
                      InvalidKeyException

Throws:

SignatureException

InvalidKeyException

update

Signature update(PublicKey publicKey,
               ByteBuffer[] byteBuffers)
                 throws InvalidKeyException,
                        SignatureException

Throws:

InvalidKeyException

SignatureException

signatureCodec

SignatureCodec signatureCodec(io.netty.buffer.ByteBuf buf)

Get the signature codec and read the signature directly from the buffer

Parameters:

buf - the buffer containing the signature at the reader index

Returns:

the signature codec

Throws:

IOException - if the signature cannot be read from the buffer

signatureSize

int signatureSize()

Returns:

the number of bytes of the signature codec
