What is Bcrypt

bcrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher

it is ideal for convert password into hash when saving in database, Besides incorporating a salt to protect against Rainbow table attacks, bcrypt is an adaptive function: over time, the iteration count can be increased to make it slower, so it remains resistant to brute-force search attacks even with increasing computation power.

Installation

npm i bcrypt-inzi

ES6 Usage

import { stringToHash, varifyHash, validateHash } from "bcrypt-inzi";

stringToHash("pakistan").then((string) => {
  console.log("hash: ", string);
});

varifyHash(
  "pakistan",
  "$2a$10$W3/bbpG0rexRwKBabxbp7efehubSnxDLM7OCEj0MEPAac98EUa9mW"
)
  .then((result) => {
    if (result) {
      console.log("matched");
    } else {
      console.log("not matched");
    }
  })
  .catch((e) => {
    console.log("error: ", e);
  });

validateHash(
  "$2a$10$W3/bbpG0rexRwKBabxbp7efehubSnxDLM7OCEj0MEPAac98EUa9mW"
).then((result) => {
  if (result) {
    console.log("hash is valid");
  } else {
    console.log("hash is invalid");
  }
});

ES5 Usage:

var bcrypt = require("bcrypt-inzi");

bcrypt.stringToHash("pakistan").then((string) => {
  console.log("hash: ", string);
});

bcrypt
  .varifyHash(
    "pakistan",

      console.log("matched");
    } else {
      console.log("not matched");
    }
  })
  .catch((e) => {
    console.log("error: ", e);
  });

bcrypt
  .validateHash("$2a$10$W3/bbpG0rexRwKBabxbp7efehubSnxDLM7OCEj0MEPAac98EUa9mW")
