Retrieving the list of available signature algorithms requires checking the services provided by all registered providers. The retrieved list of names can be used in creating a Signature object. 
    // This method is implemented in e194 Listing All Available Cryptographic Services
    String[] names = getCryptoImpls("Signature");

An example of the output:

    1.3.14.3.2.27
    SHA/DSA
