Examples of org.rhq.core.util.MessageDigestGenerator

org.rhq.core.util.MessageDigestGenerator
An object that generates a message digest or hash for algorithms such as MD5 or SHA. This class is basically a wrapper around {@link java.security.MessageDigest} and provides convenience methods making it easier to generatehashes. There are static methods in here that use MD5 as the default algorithm. If you want to use another algorithm, instantiate an instance of this object and use its instance methods.

                        String sha = null;
                        String md5 = null;
                        try {//Easier to implement here than in server side bean. Shouldn't affect performance too much.
                            md5 = new MessageDigestGenerator(MessageDigestGenerator.MD5).calcDigestString(fileItem
                                .getFile());
                            sha = new MessageDigestGenerator(MessageDigestGenerator.SHA_256).calcDigestString(fileItem
                                .getFile());
                        } catch (IOException e1) {
                            log.warn("Error calculating file digest(s)", e1);
