Frequently asked questions
What is leet speak?
Leet (also written 1337 or l33t, from “elite”) is an informal way of writing that replaces letters with similar-looking numbers and symbols, such as 3 for E and 0 for O. It started on 1980s bulletin board systems and became part of hacker and gaming culture.
What are the basic leet substitutions?
The most common are A → 4, E → 3, I → 1, O → 0, S → 5 and T → 7. These are used in the Basic level and stay readable for most people.
What does the advanced level do?
It builds letters out of several symbols, for example H → |-|, M → |\/|, N → |\|, W → \/\/ and U → |_|. It looks more cryptic and is much harder to read.
Can leet be decoded perfectly?
Not always, because the same symbol can stand for different letters: 1 can be I or L, 0 can be O, and 9 can be G or Q. The decoder uses the most common meaning and longest-match rules, so check ambiguous words.
Is leet speak a secure way to hide text or create passwords?
No. Leet substitutions are well known and password-cracking tools try them automatically, so “P455w0rd” is no stronger than “Password”. Use a long random password or passphrase instead.
What do h4x0r, n00b and pwn mean?
h4x0r is “hacker”, n00b is “newbie” (an inexperienced player), and pwn (pwned) means “own” (owned), meaning to defeat someone badly. The word swap option adds these classic terms.
