> For applications that need to generate different digests, it would be useful to be able to provide the digest as a parameter to the process.
> For example:
> {code}
> public static byte[] digest(MessageDigest messageDigest, byte[] bytes) {
>     return updateDigest(messageDigest, bytes).digest();
> }
> public static byte[] digest(final String algorithm, byte[] bytes) {
>     return digest(getDigest(algorithm), bytes);
> }
> public static String digestHex(MessageDigest messageDigest, byte[] bytes) {
>     return Hex.encodeHexString(updateDigest(messageDigest, bytes).digest());
> }
> public static String digestHex(final String algorithm, byte[] bytes) {
>     return digestHex(getDigest(algorithm), bytes);
> }
> {code}
> The same 4 methods would also be useful for InputStream (and possibly String).
> There is already a private method of this form:
> byte [] digest(MessageDigest digest, InputStream data) throws IOException
