JdkTokenBuilder

public JdkTokenBuilder(com.google.common.cache.Cache<String,AlgorithmAndKeyPair> keyCache)

Constructor.

Parameters:

keyCache - The key cache to be filled with keys created by the token builder.

Method Details

generateSignature

protected byte[] generateSignature(String kid,
 JsonWebAlgorithm algorithm,
 String headerBase64,
 String claimsBase64)
                            throws Exception

Description copied from class: AbstractTokenBuilder

Sign the token header and claims using the specified key.

Specified by:

generateSignature in class AbstractTokenBuilder

Parameters:

kid - The key to use to sign the header and claims, if this key is not found in the cache it will be generated.

algorithm - The algorithm to use to generate the key, if it is not found in the cache.

headerBase64 - The header to include in the signature.

claimsBase64 - The claims to include in the signature.

Returns:

The signature of the header and claims.

Throws:

Exception - If the security subsystem is unable to complete the operation.

generateSignature

public static byte[] generateSignature(PrivateKey privateKey,
 JsonWebAlgorithm algorithm,
 String signingInput)
                                throws Exception

Generate a signature using the JDK security classes.

Parameters:

privateKey - The private key to sign the input with.

algorithm - The algorithm to use for the signing.

signingInput - The content to be signed.

Returns:

A byte array containing the signature.

Throws:

Exception - If thrown by the JDK security subsystem.
