如何在环回 4 中加密密码？

Question

import { Member } from '../models';
import { MemberRepository} from '../repositories';
import {inject, Context} from '@loopback/context';

export class MemberController {
constructor(
 @repository(MemberRepository) private memberRepository: MemberRepository,
 @Inject('utilities.PasswordHasher') private passwordHasher: PasswordHasher,
    ) { }
}

收到此错误。

src/controllers/member.controller.ts:27:65 - 错误 TS2304：找不到 名称'PasswordHasher'。

27 @Inject('utilities.PasswordHasher') 私人密码哈希： 密码哈希，

src/controllers/member.controller.ts:27:65 - 错误 TS4063：参数 来自导出类的构造函数的“passwordHasher”已经或正在使用 私有名称“PasswordHasher”。

27 @Inject('utilities.PasswordHasher') 私人密码哈希： 密码哈希，

我可以使用哪个模块？

我是这样做的：

import {Entity, model, property} from '@loopback/repository';

const crypto = require('crypto');

@model()
export class User extends Entity{    

  [...]

  @property({
    type: 'string',
    required: false
  })
  private hashedPassword: string;

  @property({
    type: 'string'
  })
  private salt: string;

  set password(password: string){
    if(!this.salt || !this.salt.length){
      this.salt = crypto.randomBytes(32).toString('hex');
    }
    this.hashedPassword = this.encryptPassword(password);
  }

  private encryptPassword(password: string) {
    return crypto.pbkdf2Sync(password, this.salt, 10000, 512, 'sha512').toString('hex');
  };

  public checkPassword(password: string) {
    return this.encryptPassword(password) === this.hashedPassword;
  };
}
