getCryptoImpls
private static java.util.Set getCryptoImpls(java.lang.String serviceType)
Provides a list of algorithms for the specified service (which, for our purposes, is "MessageDigest". This method was only very slightly adapted (to use a TreeSet) from the Java Almanac at http://javaalmanac.com/egs/java.security/ListServices.html- Parameters:
serviceType
- The name of the service we're looking for. It's "MessageDigest"

nailMain
public static void nailMain(NGContext context) throws java.security.NoSuchAlgorithmException, java.io.IOException
Hashes client stdin, displays hash result to client stdout. Requires one command line parameter, either the name of the hash algorithm to use (e.g., "MD5") or "?" to request a list of available algorithms. Any exceptions become the problem of the user.- Throws:
java.security.NoSuchAlgorithmException
java.io.IOException
