PublicKey

public PublicKey()

PublicKey

public PublicKey(Blob keyDer)
          throws UnrecognizedKeyFormatException

Create a new PublicKey by decoding the keyDer. Set the key type from the decoding.

Parameters:

keyDer - The blob of the SubjectPublicKeyInfo DER.

Throws:

UnrecognizedKeyFormatException - if can't decode the key DER.

Method Detail

toDer

Encode the public key into DER.

Returns:

the encoded DER syntax tree.

Throws:

DerDecodingException
