====== Create a md5 hash in java with eclipse ====== Spring does have a not-well-known utility called [[http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/util/DigestUtils.html|DigestUtils]] who allows you to create md5 hashes easily. Here is an example: import org.springframework.util.DigestUtils; public class Example { public static void main( String[] args ) { System.out.println( DigestUtils.md5DigestAsHex( "Hello world".getBytes() ) ); } // main } However, bear in mind that the javadoc says that //"Mainly for internal use within the framework; consider Apache Commons Codec for a more comprehensive suite of digest utilities"//.
