Those password functions are proprietary to Adobe, though they have documented the internal algorithms. I don't think the password stuff will work if you use a non-adobe viewer. The non-adobe viewer would just try to render it without checking for a password. Apparently adobe normally encrypts the data if you use a password, so it's pretty non-workable to use a non-adobe reader against an adobe-encrypted pdf file. However, all this is based on my research of about 1 year ago - recollections might be a bit fuzzy on the details.
