                                           InvalidKeyFormatException

Creates a PublicKey from the public key information. Currently only RSA and DSA keys can be converted.

Throws:

java.security.NoSuchAlgorithmException - If the cryptographic provider does not recognize the algorithm for this public key.

InvalidKeyFormatException - If the subjectPublicKey could not be decoded correctly.
