Text Encoders

Encode, exchange and decode secret messages.

Reverse Alphabet Encoder


The encoder below assigns a number to each letter in the alphabet:

a=0, b=1, y=24, z=25, etc.

Then assigns the appropriate number to each letter you type.


The pattern is then reversed so the alphabet is counted backwards:

z=0, y=1, b=24, a=25, etc.

Each character is then swaped with the corresponding character counting backwards from the end of the alphabet.

Note: This encoder ignores (passes through) case sensitivity and special characters.

Encoder / Decoder:


Complete ASCII Encoder


This encoder is the same as above but recognizes the entire keyboard.


This includes case sensitivity and special characters:

z=%, y=&, *=u, !=~, etc.

Each character is then swaped with the corresponding character counting backwards from the end of the ASCII character set.
