pswd

Similar to pwd.
Designed with promises for cleaner code, especially with generators.
Also, pwd doesn't actually work with generators, and I'm too lazy to fix it.
bcrypt also doesn't support node 0.11 yet :( but not installing C/C++ addons
to do password hashing is always nice.
- Supports changing passwords with different iterations and lengths
- Returns a single string like bcrypt
API
var pswd = require('pswd')([options])
These options can also be set and changed by doing pswd[option] = Integer.
length <128> - salt and pbkdf2 byte length
iterations <12000> - pbkdf2 iteration count
pswd.hash(password, [salt], [iterations], [length]).then( hash => )
Creates a hash from the password with optional salt, iterations, and length arguments (used for comparision).
pswd.compare(password, hash).then( okay => )
Compare a password with a hash. okay is a Boolean.
