verifying AES-256-CBC encryption

[jonald_fyookball]

What encryption is used for wallets?
    Electrum uses AES-256-CBC to encrypt the seed and private keys in the wallet.

If I want to encrypt the seed manually to verify that its the same private key
generated as electrum, uses, can I use something like this:

I assume I would put the key in the input text field, but
what would i put in the key field?

Yes, that is a good tool.  With CBC you will need your IV too.

The key field is your password.   The tool spits out a byte array, which is base16 encoded.  You can use brainwallet.org or an ascii table to see it in another format.

thx for reply.  i meant to say put the seed as the input val.
i didnt encrypt the wallet, just memorized seed
