Level 5 Secure Text
Encrypt and Decrypt
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 passwords, messages, corporate information and the like. It is not secure enough for government encryption, according to the standards they use. However, if you choose to use any of 10 pre-designated keys (which makes it level 5), it is probably AS SECURE as government encryption in most cases. For an even higher level of security, you may use another of our routines to encrypt under a particular code and then encrypt again with this routine. However, you must decrypt in the reverse order, using the same 2 utilities, with the same Keys. If you plan to do that, test your Keys and messages prior to actual use. You may also use this routine twice, changing the Key the second time.
There are three steps involved with this utility. Enter or paste the text to encode into the text area below; any reasonable amount is acceptable as the text area does expand. Select a pre-designated key for encryption from the 10 available. Click on Encypt. You may ALWAYS decrypt or decode the result, now or later, so long as you know the Key number. Assuming you wish to select one, remember which number it is or you will not be able to decrypt the information. 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.
