My First Node.js Contribution

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.

I was working on decrypting some data from a legacy application which used Blowfish in ECB mode. After getting strange results, I started to debug node’s internals and found that ciphers with support for different key sizes were not handled correctly.

After some very pleasant interaction with the OpenSSL manual, I was able to come up with a pull request that switched some calls to a more advanced API.

I also included the necessary unit test cases to make sure this keeps working in future node releases as well.
