Jasypt 1.9.0 RELEASED! (December 18th, 2011) [DOWNLOAD and ChangeLogs] [WHAT'S NEW IN JASYPT 1.9]

Did you know? Jasypt's configuration encryption features have been featured in Spring in Action, 3rd Edition

Java Simplified Encryption

Jasypt is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works.

  • High-security, standards-based encryption techniques, both for unidirectional and bidirectional encryption. Encrypt passwords, texts, numbers, binaries...
  • Transparent integration with Hibernate.
  • Suitable for integration into Spring-based applications and also transparently integrable with Spring Security.
  • Integrated capabilities for encrypting the configuration of applications (i.e. datasources).
  • Specific features for high-performance encryption in multi-processor/multi-core systems.
  • Open API for use with any JCE provider.
  • ...and much more

With Jasypt, encrypting and checking a password can be as simple as...

BasicPasswordEncryptor passwordEncryptor = new BasicPasswordEncryptor();
String encryptedPassword = passwordEncryptor.encryptPassword(userPassword);
...
if (passwordEncryptor.checkPassword(inputPassword, encryptedPassword)) {
  // correct!
} else {
  // bad login!
}

...encrypting and decrypting a text...

BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
textEncryptor.setPassword(myEncryptionPassword);
String myEncryptedText = textEncryptor.encrypt(myText);
...
String plainText = textEncryptor.decrypt(myEncryptedText);

...and what about encrypting some sensitive data directly from Hibernate?

<class name="Employee" table="EMPLOYEE">
  ...
  <property name="address" column="ADDRESS" type="encryptedString" />
  <property name="salary" column="SALARY" type="encryptedDecimal" />
  ...
<class>

But of course, besides easy, jasypt is highly configurable. You will be able to choose encryption algorithms, salt generation and many more advanced features...
