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
  }

Constructor Detail

JcaSignedPublicKeyAndChallenge

public JcaSignedPublicKeyAndChallenge(byte[] bytes)

Parse a SignedPublicKeyAndChallenge from its DER encoding.

Parameters:

bytes - the encoded SPKAC bytes.

Method Detail

setProvider

public JcaSignedPublicKeyAndChallenge setProvider(java.lang.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(java.security.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 java.security.PublicKey getPublicKey()
                                     throws java.security.NoSuchAlgorithmException,
                                            java.security.NoSuchProviderException,
                                            java.security.InvalidKeyException

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

Returns:

the decoded public key.

Throws:

java.security.NoSuchAlgorithmException - if no KeyFactory matches the SPKI algorithm.

java.security.NoSuchProviderException - if the named provider is not registered.

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