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:
