How to fix Invalid AES key length?

Question

I am working on a text encryption and decryption project (following Struts 2)

Whenever I enter the password and the plain text I get a Invalid AES K

Answer 1

You can verify the key length limit:

int maxKeyLen = Cipher.getMaxAllowedKeyLength("AES");
System.out.println("MaxAllowedKeyLength=[" + maxKeyLen + "].");
