☀ INSTRUCTIONS
1) Enter your message/unicode text in the top window, "Text Window".
2) Hit the "Encode" button.
 (This converts contemporary text into Base 64 code, a traditional text.)
3) Enter a key (password), and click the "Encrypt" button.
 (This encrypts text into Cipher Text.)

1] To decrypt the message you would do the above in reverse order. Paste cipher text into the 2nd window, the "Results Window".
2] Enter the key (password), and click the "Decrypt" button.
3] Click on the "Decode" button.
 (This gives the original plain text.)

The "Select" button higlights text in the "Results Window".

★ HINTS - What the results look like:
Base64 code is mostly letters and numbers with the occasional plus sign "+", equal sign "=", and forward slash "/".

The Cipher Text has more keyboard symbols and punctuation!

☎ DISCUSSION
Why encrypt using a two step process?
This a hybrid of two main javascript components. The base 64 converter at best is a VERY WEAK encryptor. It has no password protection, but its strength lies in its versatility, its ability to handle UNICODE characters and different languages. The resulting base 64 text uses only conventional characters and thus is COMPATIBLE with most text applications. The encoded text RETAINS THE MESSAGE'S FORMATTING and line/carriage returns!
The text encryptor offers PASSWORD PROTECTION and can handle regular text and standard punctuation and symbols. If you plan to encrypt regular standard text, then you do not have to use the base 64 function. You can directly enter your message into the "Results Window", (the 2nd window), and proceed to encrypt the message. Non-standard characters, even slightly fancier text symbols will render the encryptor component inaccurate or unusable. By default the text runs through three encryption passes. (You have the option though to run it through only one pass by unchecking the box.) However it is still considered a WEAK encryption application. But, ... by combining the overall process with the base 64 converter, a two step process, can increase the encryption quality to a MEDIUM STRENGTH!
The full version of the original Step 64 webpage (UTF-8 encoded), is UNDER 20 KB^*, runs on javascript and should work ANYWHERE. When saved locally it should run even if there is no internet connection. (^* The unicode (aka "Unicode BOM") encoded variant is almost twice the size at 37 KB.)
