[ISSUE] Decryption failed with Message encrypted by Public Key generated by Mailvelope #15

Closed vzool closed 6 years ago

vzool commented 6 years ago

Hi,

I tried to encrypt content with RSA/4096 key generated by Mailvelope, then the web server send the encrypted message to my email, in order to use Mailvelope to decrypt and read server message from my mail box directly without copy and paste everytime. But, it fails to be decypted by Mailvelope look here:

Error message:

I even tried to add a header and footer for the encrypted message like this:

-----BEGIN PGP MESSAGE-----
EzR2$$3vUCAOMixWpGR7SRCF8w6WF3I4EwmFTmy4tytt+dmakTHeMadtkuJnWSEMeq5uM6hGy/dUEyZY/3oqcGC+ZqYFNlSjumeXDamrpZWgCiBrj1j2mCLIJ5Y3p7iA0ad1c=$d7a8998ed2d71e1d
-----END PGP MESSAGE-----

And error message changed to something else, look here:

I add a new line after header line, like this:

-----BEGIN PGP MESSAGE-----

EzR2$$3vUCAOMixWpGR7SRCF8w6WF3I4EwmFTmy4tytt+dmakTHeMadtkuJnWSEMeq5uM6hGy/dUEyZY/3oqcGC+ZqYFNlSjumeXDamrpZWgCiBrj1j2mCLIJ5Y3p7iA0ad1c=$d7a8998ed2d71e1d
-----END PGP MESSAGE-----

And error message changed again, look here:

Snippet to generate encrypted message:

$message = "Hello World";
$public = new ParagonIE\EasyRSA\PublicKey(file_get_contents("keys/Debugging_pub.asc"));
$cipher_message = ParagonIE\EasyRSA\EasyRSA::encrypt($message, $public);

keys/Debugging_pub.asc

As I think the library itself didn't complaint about the public key and the encryption process just done fine.

What I missed here, could anyone help me out?

Thanks

I tried to encrypt content with RSA/4096 key generated by Mailvelope

I don't think OpenGPG is compatible with our encryption format.

paragonie-scott commented 6 years ago

Instead of EasyRSA (which is only compatible with itself), consider switching to https://github.com/paragonie/gpg-mailer instead.

paragonie-scott commented 6 years ago

I've updated the readme to make this clearer. https://github.com/paragonie/EasyRSA#compatibility
