ptkdf: Plaintext key derivation function
Better Security Through Obscurity
I think it’s best to store passwords in plain text, but use a really strange algorithm to convert them, so they look like real passwords. Like
Password1is changed toSexyTime!Then hackers will be like, “YES! I GOT IT!” but none of the passwords will work.
What
The real salt and derived key are encoded into zero-width characters: The zero-width space, the zero-width non-joiner, the zero-width joiner, and the word joiner. A realistic-sounding password (derived from the salt) separates the salt and derived key in storage.
Usage
const ptkdf = require('ptkdf')
const hashed = await ptkdf.create({ password: 'God', keylen: 32 })
// hashed = 'thx1138'
let authenticated = await ptkdf.verify({ plaintext: 'God', hashed })
// authenticated = true
authenticated = await ptkdf.verify({ plaintext: 'thx1138', hashed })
// authenticated = false
Examples
| password | derived key |
|---|---|
| love | birdie |
| sex | xxxxxx |
| secret | boobs |
| God | thx1138 |
