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.

Where can I get either the pre-built jar or *all* of the project!

Thank you,

When I add the java package and your dot jar (from http://commons.apache.org/codec/download_codec.cgi) to a project (as a library) and try to build it, I get error messages such as the below hard (if not impossible) to remove error messages. The error messages are from the new package.

I am not nor have ever been affiliated with the Apache Project, and I've made 
no contributions to Commons Codec.

Your use of the term "package" is inconsistent with Java usage.

What exactly do you mean?

Why are you compiling the Commons Codec project? 
This is what I told you *not* to do!

Stop compiling third-party source.
