bCrypt implementation in Javascript

Question

I'm wondering if anyone has written or come across any implementations of bcrypt in JavaScript. I'm not against writing the code myself but if someone with a stonger background in cryptography has already written one why reinvent the wheel? Especially considering I'd probably come up with a shoddy wheel.

[edit]:

Following the links provided I was able to hack up a version. Its much slower then I expected.

I create a google code page for this and will try to increase the speed in the next few weeks.

Answer 1

As far as I'm aware, there is no JavaScript implementation of bcrypt. There are, however, a few JavaScript implementations of Blowfish:

• Spider Crypt (not free software)
• aamcrypt (licensed under UGPL)
• dren.ch blowfish (based on aamcrypt)
• Blowfish Remix (based on dren.ch blowfish; compatible with Perl's Crypt::Blowfish)

That should help get you started. If you're going to use one of the latter three, use the third. I mentioned the other two mainly for historical purposes.

Answer 3

Whoops, I typed that before I noticed that the link is for the version that you wrote and you mentioned it in your question. And I posted without registering so I can't edit it. Sorry about the noise, but thanks for coding that up, it is handy.
