Method Detail

generateKeyPair

KeyPair generateKeyPair(@Nullable
                        byte[] seed)

Generates a new key pair

Parameters:

seed - the optional entropy source to be used when generating a key pair

Returns:

a new key pain

getAlgorithm

Algorithm getAlgorithm()

The algorithm of the signer

Returns:

the signers algorithm

isSupportedPublicKey

boolean isSupportedPublicKey(PublicKey publicKey)

Indicates if the provided public key has an algorithm that is supported by this signer

Parameters:

publicKey - the public key to test

Returns:

true if the provide key is supported by the signer otherwise false

getPublicKeyRawBytes

byte[] getPublicKeyRawBytes(PublicKey publicKey)

Obtains the raw bytes from a public key so can be used in casper types

Parameters:

publicKey - the public key to obtain the raw bytes from

Returns:

the raw bytes of the provided key

createPublicKey

PublicKey createPublicKey(byte[] publicKey)

Creates a public key from the provided raw bytes

Parameters:

publicKey - the public key raw bytes

Returns:

a new PublicKet created from the provided bytes

convertFromDER

byte[] convertFromDER(byte[] signed)

convertToDER

byte[] convertToDER(byte[] signed)
