🔐 @pitech-lib/cipher-kit

A secure and reusable encryption module for NestJS microservices, using AES-256-GCM. Can be used as a global module or as a direct service provider.

📦 Installation

npm install @pitech-lib/cipher-kit

Setup

Option 1: Use as a Global Module (recommended)

Since CipherModule is marked with @Global(), importing it once in your root module makes it available app-wide:

// app.module.ts
import { Module } from '@nestjs/common';
import { CipherModule } from '@pitech-lib/cipher-kit';

@Module({
  imports: [CipherModule],
})
export class AppModule {}

Option 2: Use as a Provider Manually (optional)

// your.module.ts
import { Module } from '@nestjs/common';
import { CipherService } from '@pitech-lib/cipher-kit';

@Module({
  providers: [CipherService],
})
export class YourModule {}

and in your service:

@Injectable()
export class TenantService {
  constructor(private readonly cipherService: CipherService) {}

  handleEncryption() {
    const key = this.configService.get<string>('CIPHER_KEY');
    const plain = 'sk_live_123abc';

    const encrypted = this.cipherService.encrypt(plain, key);
    const decrypted = this.cipherService.decrypt(encrypted, key);

  }
}
