After I added initial support for Authenticated Encryption to Node.js last year, someone else built on this and extended the API with the ability to use Associated Data, putting the AD into AEAD. I toyed with it a little and found that the generated errors could use some love.
After my previous two contributions to the Node.js crypto module were purely fixes to enable interoperability with legacy software, my newest feat is actually stepping up node’s game by adding initial support for Authenticated Encryption to the lower-level API.
My second contribution to the Node.js crypto module has been merged. This time it’s about controlling padding.
Node.js v0.6.4 has just been released and it ships with my first commit to the runtime system, namely to the crypto module.
