You apparently brought in part, not all, of the source code for the library you want to 
use. This is not conventional or optimal.

Instead, either download or build the JAR, ensuring thus that it contains *all* the 
project (Commons Codec in this case). Since Apache Commons is, well, common, 
unless you're contributing to the project download the JAR rather than build it.

See the Java documentation for how to include JARs in the classpath with the 
"-classpath" ("-cp" for short) argument to the Java tools.

What does "better" mean to you?

Apache Commons Codec is not an encryption library, so presumably any 
encryption library would be better.

As for your other errors, the messages seem clear enough.

Don't use raw types.

Use generics correctly.
