Method Detail

sign

public String sign(String data,
                   String algorithm)
            throws JWSException

Description copied from interface: JWSSigner

Signs the specified input data.

Specified by:

sign in interface JWSSigner

Parameters:

data - This input should contain the header and body part of the JWT. BASE64URL(UTF8(JOSE header)) || '.' || BASE64URL(JWS payload)

algorithm - JWS algorithm used to secure the JWS. This is the 'alg' header parameter.

Returns:
