public class JcaSignedPublicKeyAndChallenge
extends SignedPublicKeyAndChallenge

This is designed to parse the SignedPublicKeyAndChallenge created by the KEYGEN tag included by Mozilla based browsers.

 PublicKeyAndChallenge ::= SEQUENCE {
   spki SubjectPublicKeyInfo,
   challenge IA5STRING
 }

 SignedPublicKeyAndChallenge ::= SEQUENCE {
   publicKeyAndChallenge PublicKeyAndChallenge,
   signatureAlgorithm AlgorithmIdentifier,
   signature BIT STRING
 }

JcaSignedPublicKeyAndChallenge

public JcaSignedPublicKeyAndChallenge(byte[] bytes)

Parse a SignedPublicKeyAndChallenge from its DER encoding.

Parameters:

bytes - the encoded SPKAC bytes.

Method Details

setProvider

public JcaSignedPublicKeyAndChallenge setProvider(String providerName)

Return a new holder that pins KeyFactory lookups to the named JCE provider.

Parameters:

providerName - the name of the JCE provider to use.

Returns:

a new JcaSignedPublicKeyAndChallenge bound to providerName.

setProvider

public JcaSignedPublicKeyAndChallenge setProvider(Provider provider)

Return a new holder that pins KeyFactory lookups to the supplied JCE provider.

Parameters:

provider - the JCE provider to use.

Returns:

a new JcaSignedPublicKeyAndChallenge bound to provider.

getPublicKey

public PublicKey getPublicKey()
                       throws NoSuchAlgorithmException,
NoSuchProviderException,
InvalidKeyException

Return the public key carried by the SPKAC as a JCA PublicKey, decoded via the provider configured by setProvider(String).

Returns:

the decoded public key.

Throws:

NoSuchAlgorithmException - if no KeyFactory matches the SPKI algorithm.

NoSuchProviderException - if the named provider is not registered.

InvalidKeyException - if the SPKI cannot be decoded into a usable key.
