Yes, I tried the following code:
SecretKeySpec keySpec = new
SecretKeySpec(JavaUtils.getBytesFromFile(keyFile), algorithm);
SecretKeyFactory skf = SecretKeyFactory.getInstance(algorithm);
SecretKey key = skf.generateSecret(keySpec);
The exception I receive is
java.security.NoSuchAlgorithmException: AES not found
at javax.crypto.SecretKeyFactory.getInstance(SecretKeyFactory.java:86)
But how can that be? I used AES for encryption�
Any ideas? Thanks Dominik
