The Advanced Encryption Standard (AES), also known by its original name Rijndael is a specification for the encryption of electronic data. It describes a symmetric-key algorithm using the same key for both encrypting and decrypting. AES Encryption: Encrypt and decrypt online.

How can I create my own key? I have tried padding it out to 256 bits, but then I get.
Java 256-bit AES Password-Based Encryption (6)
Consider using the Spring Security Crypto Module
The Spring Security Crypto module provides support for symmetric encryption, key generation, and password encoding. The code is distributed as part of the core module but has no dependencies on any other Spring Security (or Spring) code.
It's provides a simple abstraction for encryption and seems to match what's required here,
The 'standard' encryption method is 256-bit AES using PKCS #5's PBKDF2 (Password-Based Key Derivation Function #2). This method requires Java 6. The password used to generate the SecretKey should be kept in a secure place and not be shared. The salt is used to prevent dictionary attacks against the key in the event your encrypted data is compromised. A 16-byte random initialization vector is also applied so each encrypted message is unique.
A look at the internals reveals a structure similar to erickson's answer.
As noted in the question, this also requires the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy (else you'll encounter InvalidKeyException: Illegal Key Size). It's downloadable for Java 6, Java 7 and Java 8.
Example usage
And sample output,
I need to implement 256 bit AES encryption, but all the examples I have found online use a 'KeyGenerator' to generate a 256 bit key, but I would like to use my own passkey. How can I create my own key? I have tried padding it out to 256 bits, but then I get an error saying that the key is too long. I do have the unlimited jurisdiction patch installed, so thats not the problem :)
Ie. The KeyGenerator looks like this ..
EDIT
I was actually padding the password out to 256 bytes, not bits, which is too long. The following is some code I am using now that I have some more experience with this.
The 'TODO' bits you need to do yourself :-)
Adding to @Wufoo's edits, the following version uses InputStreams rather than files to make working with a variety of files easier. It also stores the IV and Salt in the beginning of the file, making it so only the password needs to be tracked. Since the IV and Salt do not need to be secret, this makes life a little easier.
HowToDoInJavaBy Lokesh Gupta Filed Under: Java SecurityLearn to use Java AES 256 bit encryption to create secure passwords, and decryption for password validation. To read simple AES encryption, read linked post.
1. AES – Advanced Encryption Standard
AES is a symmetric encryption algorithm. It was intended to be easy to implement in hardware and software, as well as in restricted environments and offer good defenses against various attack techniques.
AES is block cipher capable of handling 128 bit blocks, using keys sized at 128, 192, and 256 bits. Each cipher encrypts and decrypts data in blocks of 128 bits using cryptographic keys of 128-, 192- and 256-bits, respectively. It uses the same key for encrypting and decrypting, so the sender and the receiver must both know — and use — the same secret key.
In below encryption and decryption example, I have used base64 encoding in UTF-8 charset. It is done for displaying the output of program. If your application, you can store and validate the data in byte array format as well.
2. AES 256 Encryption
Java program to encrypt a password (or any information) using AES 256 bits.
Do not forget to use same secret key and salt in encryption and decryption.
3. AES 256 Decryption

Let’s test our AES256 encryption and decryption methods with a simple string.
Program output.
Clearly, we are able to use AES256 encryption to encrypt a string, and decryption to get back original string from encrypted string.
Happy Learning !!
