I remember in ~2005-2009 while I was in high school, javascript password-protection was my main interest, since I only had access to free hosts that hosted static files. Most of them just focused on obfuscating the password in the source (most by encoding, the fancy ones through some opaque evals), but I came across one during that time that claimed to use AES and even had a not-insignificant cash prize for defeating it. I really wish I could find that site... would be fun to give a shot at cracking it given what I know now. Anywho, in my search for that site, I found a pretty good tutorial considering it's age (1997!) on implementing DES in javascript to achieve something similar[0].
