# 설치 가이드

1. 코드 내려받기

git clone https://github.com/indutny/asn1.js

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd asn1.js

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm start

개발/실행 서버를 켭니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

# ASN1.js

ASN.1 DER Encoder/Decoder and DSL.

## Example

Define model:

```javascript
var asn = require('asn1.js');

var Human = asn.define('Human', function() {
  this.seq().obj(
    this.key('firstName').octstr(),
    this.key('lastName').octstr(),
    this.key('age').int(),
    this.key('gender').enum({ 0: 'male', 1: 'female' }),
    this.key('bio').seqof(Bio)
  );
});

var Bio = asn.define('Bio', function() {
  this.seq().obj(
    this.key('time').gentime(),
    this.key('description').octstr()
  );
});
```

Encode data:

```javascript
var output = Human.encode({
  firstName: 'Thomas',
  lastName: 'Anderson',
  age: 28,
  gender: 'male',
  bio: [
    {
      time: +new Date('31 March 1999'),
      description: 'freedom of mind'
    }
  ]
}, 'der');
```

Decode data:

```javascript
var human = Human.decode(output, 'der');
console.log(human);
/*
{ firstName: <Buffer 54 68 6f 6d 61 73>,
  lastName: <Buffer 41 6e 64 65 72 73 6f 6e>,
  age: 28,
  gender: 'male',
  bio:
   [ { time: 922820400000,
       description: <Buffer 66 72 65 65 64 6f 6d 20 6f 66 20 6d 69 6e 64> } ] }
*/
```

### Partial decode

Its possible to parse data without stopping on first error. In order to do it,
you should call:

```javascript
var human = Human.decode(output, 'der', { partial: true });
console.log(human);
/*
{ result: { ... },
  errors: [ ... ] }
*/
```
