OFB mode - Uncaught TypeError: Argument 1 passed to mcrypt_enc_get_iv_size() must be an instance of phpseclib3\Crypt\Common\SymmetricKey, bool given about mcrypt_compat HOT 9 CLOSED

So I wouldn't really call this a bug since https://github.com/phpseclib/mcrypt_compat doesn't mention support for ofb. phpseclib supports mcrypt's nofb mode but not it's ofb mode.

Now mcrypt_compat does implement cfb and ncfb. That corresponds to phpseclib's CFB8 and CFB modes, respectively. I can look into adding support for OFB8 (what mcrypt's ofb8 more accurately corresponds to) and model it after phpseclib/phpseclib@8e6948f .

I do have some other higher priority phpseclib related stuff I'm working on, however, so, baring a patreon donation to motivate me lol I can't give you an ETA. Maybe a few weeks? idk

I sort of figured it was going to be a "not supported" thing vs. a bug - that's helpful to have confirmed, thanks!

This is definitely important to our company - it would make some migration of some existing legacy code much easier for us.

It's a little hard for me to get recurring donations approved, but do you know if Patreon will let us do a one-time donation? Or pay yearly instead of monthly? I would certainly get a one-time somewhere in the $500 or $750 range approved if that helps keep this on your radar? Thoughts?

from mcrypt_compat.

For $750 I'll try to have it done by early next week! :D

For a one time payment you could PayPal me. But hold off until I've actually done the work! I'll get started when I get home from work today!

Awesome! I have it approved on my end - if we can get stuff we had previously encrypted with rijndael-256 in ofb decrypted without depending on mcrypt, that would make it nice and quick for us to pull mcrypt out of our Docker images for sure!

from mcrypt_compat.

The newest release of mcypt_compat should have full support for ofb!

WOOHOO! THANKS! Can you send me your PayPal address? (Or reach out to me at [email protected] if you want to keep the email adddr off the issue?)

from mcrypt_compat.

[email protected] is my address! https://sourceforge.net/donate/index.php?group_id=198487 is a direct link you can use to do the donation.

Thanks!
