Quick answer
A generator creates random private keys, derives public addresses, and checks whether each address matches the pattern.
It does not calculate a private key from the visible pattern.
How to think about it
Vanity address tools work best when the target pattern is short and easy to validate.
Every extra fixed character multiplies the expected work, so a pattern that looks only slightly longer can be much harder.
Safety notes
Generated keys are sensitive. Never upload, log, or share private keys or secret keys.
A visually interesting address does not make a wallet safer and should not be treated as financial advice.
