What are some of the safe / reliable cryptographic libraries for JavaScript? For those who have used it, what is your opinion of them? Thanks.
Google closure
Google's closing library used has been quite successful for a while

Specific crypt documentation here

phpjs.org
Sometimes for simpler tasks I also used standalone functions like md5 or sha1 from phpjs.org
crypto js
Although it was never used personally, I heard very good things about this library.
