I am currently creating application using Java, I googled password encryption with java but the results are so enormous I felt overwhelmed. How would I encrypt and decrypt a password using Java? And what is the best practice for encrypting and decrypting passwords? I am guessing MD5 is not a way to go since it is a one way hash. I am using struts2 as my framework, was wondering if they provide password encryption

AES is an Advanced Encryption Standard algorithm. It is a type of symmetric, block cipher encryption and decryption algorithm. It works with key size 128, 192, and 256 bits. It uses a valid and similar secret key for both encryption and decryption.
Password-Based Encryption using Salt and Base64: The password-based encryption technique uses plain text passwords and salt values to generate a hash value. And the hash value is then encoded as a Base64 string. Salt value contains random data generated using an instance of Random class from java. util package.
Updated:
Try JBCrypt:
String password = "MyPassword123";
String hashed = BCrypt.hashpw(password, BCrypt.gensalt(12));
System.out.println(hashed); // $2a$12$QBx3/kI1SAfwBDFOJK1xNOXK8R2yC7vt2yeIYusaqOisYbxTNFiMy
Download jBCrypt-0.3 from here, check README file for more details.
