Groovy Goodness: Calculate MD5 And SHA Hash Values

Groovy adds a lot of useful methods to the String class. Since Groovy 2.5.0 we can even calculate MD5 and SHA hash values using the methods md5 and digest. The md5 method create a hash value using the MD5 algorithm. The digest method accepts the name of the algorithm as value. These values are dependent on the available algorithms on our Java platform. For example the algorithms MD2, MD5, SHA-1, SHA-256, SHA-384 and SHA-512 are by default available.

In the next example we use the md5 and digest methods on a String value:

Written with Groovy 2.5.0.
