ASN.1 DER Encoder/Decoder and DSL for Node.js with no dependencies
This is a fork of @indutny's asn.js
library with the following
changes made:
.int()
returns are native BigInt
valuesstandard
Define model:
const asn = require('@panva/asn1.js')
const 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)
)
})
const Bio = asn.define('Bio', function () {
this.seq().obj(
this.key('time').gentime(),
this.key('description').octstr()
)
})
Encode data:
const output = Human.encode({
firstName: 'Thomas',
lastName: 'Anderson',
age: 28,
gender: 'male',
bio: [
{
time: new Date('31 March 1999').getTime(),
description: 'freedom of mind'
}
]
}, 'der')
Decode data:
const 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: 28n,
gender: 'male',
bio:
[ { time: 922820400000,
description: <Buffer 66 72 65 65 64 6f 6d 20 6f 66 20 6d 69 6e 64> } ] }
*/
Its possible to parse data without stopping on first error. In order to do it, you should call:
const human = Human.decode(output, 'der', { partial: true })
console.log(human)
/*
{ result: { ... },
errors: [ ... ] }
*/
