How use the same SecretKey (not random each time it runs) ?

[Daniel Rodriguez Hernandez]

Hi everybody.

I need to encrypt and decrypt using the same SecretKey for AES, but if you use the method "GenerateKey ()", it generates a new key every time ..

Is there a way to encrypt and decrypt with a key defined by me, not creating a new one every time?

Thank you.

use a SecretKeySpec.

Ok, thank you..

I used SecretKeySpec but it threw me a "Invalid length key 7 bytes"... Then I read that the key must be of length 16 bytes... i.e, a character per byte, 16 character..

Now It works fine.

Thank you
