How can I use Java MD5 MessageDigest without catching NoSuchAlgorithmException?

Question

In Java, if I want to compute an MD5 sum, I need to be aware of possible exceptions:

try {
   MessageDigest md = MessageDigest.getInstance("MD5");
   // Do stuff
} catch (NoSuchAlgorithmException e) {
   // Can't happen...
}

However, according to the JVM spec, MD5 must be supported, so the exception should never be thrown. Is there a different access pattern that allows me to write more elegant code?

Answer 1

Instead of MessageDigest you can use common.apache DigestUtils. This is easy to use and no need to take such long procedure to digest data like MessageDigest does.

DigestUtils.md5("String to digest");
