Method Detail

compute

public static Base64URL compute(JWK jwk)
                         throws JOSEException

Computes the SHA-256 thumbprint for the specified JWK.

Parameters:

jwk - The JWK. Must not be null.

Returns:

The JWK thumbprint.

Throws:

JOSEException - If the SHA-256 hash algorithm is not supported.

compute

                                JWK jwk)
                         throws JOSEException

Computes the thumbprint for the specified JWK.

Parameters:

hashAlg - The hash algorithm. Must not be null.

jwk - The JWK. Must not be null.

Returns:

The JWK thumbprint.

Throws:

JOSEException - If the hash algorithm is not supported.

compute

public static Base64URL compute(String hashAlg,
                                LinkedHashMap<String,?> params)
                         throws JOSEException

Computes the thumbprint for the specified required JWK parameters.

Parameters:

hashAlg - The hash algorithm. Must not be null.

params - The required JWK parameters, alphanumerically sorted by parameter name and ready for JSON object serialisation. Must not be null.

Returns:

The JWK thumbprint.

Throws:
