What is leet speak (1337)?
Leet speak was born on the BBSes and forums of the '80s and '90s: the word "elite" became "leet" and then "1337", written by swapping letters for numbers and symbols that look alike. Originally it was a way to slip past automatic word filters; today it lives on mostly in gaming, in nicknames, and in usernames when the "normal" one is already taken.
One practical warning: using leet to "strengthen" a password (like p4ssw0rd) does not make it secure. Password-cracking tools automatically try every leet variant of common words, so those substitutions add essentially no protection.
How the conversion works (and its limits)
Level 1 applies the six classic substitutions (a→4, e→3, i→1, o→0, s→5, t→7) and stays readable to almost anyone. Level 2 adds b→8, g→9, z→2 and six symbol combos: |) for d, |-| for h, |< for k, |\/| for m, |\| for n and \/\/ for w. It's more dramatic, but harder on the eyes. Uppercase and lowercase convert the same way, and accented letters stay as they are.
Decoding is approximate: it reads from left to right, recognises the level 2 symbol combos and turns numbers back into the most likely letters, but it can never be perfect. The digit 1 always comes back as «i» even when it stood for an «l», converted letters come back in lowercase, and the digits of a real number turn into letters: «h4ck3r 1990» comes back as «hacker iggo». Always double-check the result before using it.
Who listens instead of looking
A screen reader reads leet as it is written: digits as numbers and symbols one by one, so «h4ck3r» sounds like letters and numbers mixed together and |-| becomes a string of symbol names. People who listen to it understand it less well than people who look at it: fine for a nickname, not for a message that has to be understood.
