Easy to use encryption library for java

If you are looking for an easy to user encryption library, the lightest that I found was jcrypt :

<dependency>

    <groupId>org.mindrot</groupId>
    <artifactId>jbcrypt</artifactId>
    <version>0.3m</version>
</dependency>

BCrypt.hashpw(password, BCrypt.gensalt(10));
BCrypt.checkpw(pwd1, pwd2);

I need to  specify that I do not need a very secure one because I am not handling sensitive data.

Slf4j compatibility issues with Dropwizard and Hibernate annotations

While writing a project using dropwizard(0.7.1) and hibernate annotations(3.5.5-Final) I ran into a problem with the versions of slf4j which is a dependency of both but with different versions. dropwizard uses v1.7.6 and hibernate uses 1.5.8.

The solution was to add in the pom file the following dependency:

<dependency>

      <groupId>io.dropwizard</groupId>

      <artifactId>dropwizard-core</artifactId>

      <version>0.7.1</version>

      <scope>compile</scope>

      <exclusions>

        <exclusion>

          <artifactId>slf4j-api</artifactId>

          <groupId>org.slf4j</groupId>

        </exclusion>

      </exclusions>

    </dependency>
