node-crypto-cli's Issues

Decrypted jpg file can't open

Hello,

I am trying to write myself "simple" code to encrypt/decrypt jpg images using createCipheriv(). I really stuck on it for 3 days in a row, so I decided to test ready lib and eventually take a look where I am wrong...
So I installed yours cli and guess... it did the same problem as I had three days in a row - the decrypted image won't open! It gives on MAC error message: "Error 3: Unsupported image format".

Any idea what is wrong with this? I really have no idea...

how to reproduce: paste any jpg image, encrypt it (it will give success), decrypt it, it will give you success again, however, the jpg becomes unusable ....

Any help will be greatly appreciated!
