Encrypt-response NPM

encrypt-response

NestJs library for encrypt response.

Nest.js (Install)

Requirements:

Nest.js
npm (Node.js package manager)

npm install encrypt-response

Usage

Import EncryptModule to your current module and pass your private_key:

import { EncryptModule } from 'encrypt-response';

@Module({
  imports: [EncryptModule.register('private_key')]
})

Import Encrypt decorator and EncryptInterceptor to your current controller and pass your algorithm from Algorithm enums:

import { Encrypt, EncryptInterceptor } from 'encrypt-response';
import { Algorithm } from 'encrypt-response/dist/common/enum';

@Get()
@Encrypt(Algorithm.AES)
@UseInterceptors(EncryptInterceptor)
getHello(): any {
  return this.appService.getHello();
}

If you need decrypt cipher text in your back-end project, you can use EncryptService:

import { EncryptService } from 'encrypt-response';
import { Algorithm } from 'encrypt-response/dist/common/enum';

constructor(
  private readonly encryptService: EncryptService,
) {}

decrypt(): any {
  console.log(
    this.encryptService.decrypt(
      'U2FsdGVkX18bd5ZxKAzmHipM9l+gowyOSLcudi6EOWM=',
      Algorithm.AES,
    ),
  );
}
