AES-CFB support for web-crypto

Developers API
1

Hi all,

I saw that Cloudflare’s WebCrypto does not support AES-CFB [1], however, this algorithm is already implemented for WebCrypto [2].

Is it an outdated documentation? If no, we are needing this algorithm to create a worker. Does Cloudflare intend to have AES-CFB implemented?

Thank you in advance.

regards,

Paulo Angelo

Why do you need to use CFB mode?

Hi Mnordhoff,

We have to integrate with a already created system.

I had a look at Web Cryptography API and AES-CFB is apparently not implemented. :frowning:

We solved the problem implementing CBC mode in our system.

Case closed!
