TEA Encrypt / Decrypt

• This is a JavaScript code. This code is executed in YOUR browser at YOUR computer. Nothing is sent to the server. All information disappears after closing your Internet browser. 
• 128 bits (16 characters) from the Key will be used to encrypt the Value, using Wheeler & Needham’s Tiny Encryption Algorithm.

Encryption:

1. Enter your password (key) - any printable characters (up to 16)

2. Type or paste your message in the upper text area

3. Press "Encrypt it"

4. Get the encrypted text in the middle text area. It is ready to paste into your e-mail (not as an attachment)

Decryption:

1. Enter your password (key) - any printable characters

2. Paste   in the middle text area the encrypted message (one long line, without extra characters and spaces in the beginning and the end)

3. Press "Decrypt it"

4. Get the restored text in the lower text area. 

• The current version is based on Chris Veness algorithm (Movable Type Ltd: www.movable-type.co.uk ). I slightly modified the code(added escape(s), see the page source) to assure that only printable characters are used.
• My Pascal implementation of TEA is available here.
