Versions

ASN1.js

ASN.1 DER Encoder/Decoder and DSL for Node.js with no dependencies

Acknowledgement

This is a fork of @indutny's asn.js library with the following changes made:

all .int() returns are native BigInt values
lint using standard

Example

Define model:

1const asn = require('@panva/asn1.js')
2
3const Human = asn.define('Human', function () {
4  this.seq().obj(
5    this.key('firstName').octstr(),
6    this.key('lastName').octstr(),
7    this.key('age').int(),
8    this.key('gender').enum({ 0: 'male', 1: 'female' }),
9    this.key('bio').seqof(Bio)
10  )
11})
12
13const Bio = asn.define('Bio', function () {
14  this.seq().obj(
15    this.key('time').gentime(),
16    this.key('description').octstr()
17  )
18})

Encode data:

1const output = Human.encode({
2  firstName: 'Thomas',
3  lastName: 'Anderson',
4  age: 28,
5  gender: 'male',
6  bio: [
7    {
8      time: new Date('31 March 1999').getTime(),
9      description: 'freedom of mind'
10    }
11  ]
12}, 'der')

Decode data:

1const human = Human.decode(output, 'der')
2console.log(human)
3/*
4{ firstName: <Buffer 54 68 6f 6d 61 73>,
5  lastName: <Buffer 41 6e 64 65 72 73 6f 6e>,
6  age: 28n,
7  gender: 'male',
8  bio:
9   [ { time: 922820400000,
10       description: <Buffer 66 72 65 65 64 6f 6d 20 6f 66 20 6d 69 6e 64> } ] }
11*/

Partial decode

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

1const human = Human.decode(output, 'der', { partial: true })
2console.log(human)
3/*
4{ result: { ... },
5  errors: [ ... ] }
6*/
