Hashing of Key-Value pair on Hashpass.com

Question

Just found this website: hashpass.com and here is the JS implementation which they use to encrypt the key-value pair: http://hashapass.com/sha1.js

So, can there be a "simple" and obvious alternative to this?

Thanks

I'm not sure how secure this is. For one thing, the output is a short Base64 string. Due to its length and restricted character set, it should be easier to brute-force than a regular password that avoids the common and dictionary values while combining alpha, numeric and other.
