Codes for Kids

Codes are fun! Below is a simple number substitution code. It replaces each letter in a message with a number (A with 1, B with 2 ... Z with 26). Type a message in the "Text to code/decode" box below and click on the "Code" button. Your message will be encrypted (changed to numbers) and placed into the "Result" box. If you want to decode a message, place a coded message in the "Text to code/decode" box and click on the "Decode" button. Tip: you can cut and past from the "Results" box to the "Code/Decode" box. Warning: This code does not work well if the original message includes numbers.
