Step 1: use openssl to create a new AES key. Below is an example of a command and the result. The iv string can be copy and pasted into the Initialization vector field of an AES encryption/decryption snap.
$ openssl enc -aes-256-cbc -base64 -k secret -P -md sha1
salt=18F3973C70475135
key=1B76BAE6805E9EEF5C4A34AB26B1D6F68A5CA6965DD1B157AFAD25AE029C4874
iv =8E204167430AA0CD292C35DFB52D86F8
Step 2: The AES encryption/decryption snap required the AES key to be a base64 encoded string. Below is an example of a command and the result of base64-encoding the binary AES key:
$ echo "1B76BAE6805E9EEF5C4A34AB26B1D6F68A5CA6965DD1B157AFAD25AE029C4874" | xxd -r -p | base64
