# NestJSX-Crypto

`Crypto` module for [NestJS](https://nestjs.com/) framework provides some functions for security features like `AES key`, `Key pair`, `PKCS12`, `RSA key`, `Certificate`, `JWT` and more.

This module is a wrapper to use [@akanass-rx-crypto](https://github.com/akanass/rx-crypto) library inside [NestJS](https://nestjs.com/) `application` in an easy way.

**All most important crypto features in only one module.**

## Using crypto module inside NestJS application

### `yarn` or `npm` it in your `package.json`

```bash
$ npm install --save @akanass/nestjsx-crypto @nestjs/common rxjs reflect-metadata

$ yarn add @akanass/nestjsx-crypto @nestjs/common rxjs reflect-metadata
```

```javascript
"dependencies": {
    "@akanass/nestjsx-crypto": "^3.0.0",
    "@nestjs/common": "^8.0.11",
    "reflect-metadata": "^0.1.13",
    "rxjs": "^7.4.0"
    //...
}
//...
```

### import `CryptoModule`

```typescript
import { CryptoModule } from '@akanass/nestjsx-crypto';
import { Module } from '@nestjs/common';
import { NestJSServiceWithCrypto } from './crypto.service.ts';

@Module({
    imports: [
        CryptoModule
    ],
    providers: [
        NestJSServiceWithCrypto
    ]
})
export class NestJSModuleNeedsCryptoModule {}
```

### use it anywhere

You can use `AesService`, `HashService`, `PemService`, `RandomStringService`, `JwtService` and `RsaService` anywhere in your module with **dependency injection**.

```typescript
import { RsaService, NodeRSA } from '@akanass/nestjsx-crypto';
import { Injectable } from '@nestjs/common';

@Injectable()
export class NestJSServiceWithCrypto {
    constructor(private readonly _rsaService: RsaService) {}
    
    createRsaKey(): void {
        this._rsaService.createKey().subscribe(
            (k: NodeRSA) => console.log(k), // Show NodeRSA instance in console
            e => console.error(e) // Show error in console
        );
    }
}
```
