Compact and fast crypto library for hashing and comparing hashes.
npm i @seishinverse/crypto
# or with yarn
yarn add @seishinverse/crypto
# or with pnpm
pnpm i @seishinverse/cryptoIn first import CryptoModule in AppModule.
import { CryptoModule } from '@seishinverse/crypto';
import { Module } from '@nestjs/common';
@Module({
imports: [CryptoModule.forRoot()],
})
export class AppModule {}Then inject service with decorator InjectCrypto.
import { CryptoModule, InjectCrypto, CryptoService } from '@seishinverse/crypto';
import { Injectable } from '@nestjs/common';
@Injectable()
export class AppService {

/*
Generating salt and hashing password.

// ...

/*
Comparing current password with incoming.

signIn() {
const currentPassword = 'very secret pass!';
const incomingPassword = 'not secret pass:(';
const isPasswordEqual = this.cryptoService.compare(incomingPassword, currentPassword);
console.log(isPasswordEqual); // false
}
}Import CryptoService and initialize it.
import { CryptoService } from '@seishinverse/crypto';
const cryptoService = new CryptoService();
/*

const isPasswordEqual = this.cryptoService.compare(incomingPassword, currentPassword);
console.log(isPasswordEqual); // false
