About
MobileKey Cipher is a substitution cipher inspired by the symbol layer of a mobile keyboard, where each letter maps to the symbol or number you'd find on a phone's keyboard.
Think of it like leet speak, but instead of random substitutions, every mapping follows the logic of what's physically on your mobile keyboard.
It converts this:
Plain text
Encoded output
Not cryptographically secure by the way!
Best used for fun, lore, OR Args!
