Here's a fun little project if you're tech saavy.
So, I downloaded the PascalCoin wallet
http://www.pascalcoin.org/and it lets you export private keys, but the private keys are encrypted with AES.
I'm not sure the proper aes format though.
My goal: to take secp256k1 private key and use same encryption as wallet uses so that i can start with my own key:
See here:

1. must start with bitcoin private key
2. must use readily available tool for aes encrypt into hex format
3. must be importable into pasc wallet
