A library for encrypting/decrypting any JavaScript value as JsonWebEncryption (JWE)

### Features

 - Promise based interface
 - Encrypting/Decrypting anything from (number, string, boolean, array, date, regex, buffer, object)
 - TypeScript support
 - support for symetric JsonWebKeys { kty: 'oct' }
 - supported algorithms 'A256KW', 'A256GCM', 'A256GCMKW', 'A128CBC-HS256'
 - Continous integration with [Travis](https://travis-ci.org/adorsys/jwe-codec)

### Installation

```bash
npm install @adorsys/jwe-codec
```

### Usage


```js
const jwe = require('@adorsys/jwe-codec')

const key = {
  kty: 'oct',
    alg: 'A256GCM',
    use: 'enc',
    k: '123456789abcdefghijklmnopqrstuvwxyz12345678'
}

...
```

#### with async/await

```js
...

;(async () => {
    const codec = await jwe(key)
    const cipher = await codec.encrypt(42)
    // => eyJlbmMiOiJBMjU2R0NNIiwiYWxnIjoiZGlyIiwia2lkIjoialpESEVqN0ZhR3N5OHNUSUZLRWlnejB4TjFEVWlBZWp0S1ZNcEl2Z3dqOCJ9..lipFQHmBiBhsTRqE.4rLjRCOj7JZIKOpToIhOp8cJgvfNWl4Yo__VnkO7yRIYjrCLdGRl5fcR.9S_DwYmkpdLap1yyYYq44A​​​​​
    const answer = await codec.decrypt(cipher) 
    // => 42
})()
``` 

#### with Promises

```js
...

jwe(key).then(codec => {
    codec.encrypt(42).then(cipher => {
        codec.decrypt(cipher).then(answer => {
            console.log(answer) // 42
        })
    })
})
```
