The Morbit code is a variant of the Morse code that performs a polygramic substitution in addition to Morse coding.
The Morbit code uses a numeric index (from 1 to 9) that is linked to Morse character pairs consisting of a dot, dash or space. This index is created using a keyword. The keyword should be 9 letters long.
Example: The keyword “WISECRACK” produces the index 958427136 by sorting the letters alphabetically and assigning them to the numbers 1234567879.
WISECRACK -> ACCEIKRSW <=> 123456789
958427136
The Morse code pairs are then assigned to the digits.
WISECRACK
958427136

The first step in encryption is to encode the original message in Morse code. The characters are separated by a “x” and words are separated by double “xx”.
Example: The message “MORE BITS” is represented in Morse code as “-x--x.-.x.xx-...x...x-x...”.
In the second part of the encoding, the Morse characters are divided into pairs of 2 characters and linked with the corresponding index value.
Example: “-x -- x. -. x. xx -. .. x. .. x- x. ..” corresponds to the numbers 7 2 1 4 1 9 1 9 3 9.
The encrypted result is therefore “7214191939”.
