Level 5 Secure URL
Encode and Decode
This converter requires the use of Javascript enabled and capable browsers. This script creates an encryption and decryption algorithm that allows for reasonably secure (level 5) coding and decoding. No Javascript routines are totally secure. This is adequate for URLs or very short messages only. It is not secure enough for government encryption, according to the standards they use. However, if you choose to use all three encoding routines (which makes it level 5), it is probably MORE SECURE than government encryption in most cases. However, you must decrypt in the reverse order, using the same routines. If you plan to do that, test your URLs and messages prior to actual use.
There are three steps involved with this utility. Enter or paste the URL to encode into the same area; an amount of 500 characters is acceptable as the text area does expand. Put in a URL for encryption by typing or pasting it into the field. Click on URL Encode, then Base64 Encode, then HEX Encode. You may ALWAYS decrypt or decode the result, now or later, so long as you know the order of the encryption. Please be aware that with early generation browsers, this script can have erratic and unstable behavior. We suggest the use of Internet Explorer 5, 6 or 7, though many other browsers work fine.
