@complycloud/asn1-der
Javascript library for DER and PEM serialization/deserialization of Abstract Syntax Notation One (ASN.1)
Uses the ASN.1 Object Model from @complycloud/asn1.
Installation
npm install @complycloud/asn1-der
Usage
import { Universal } from '@complycloud/asn1';
import { DERSerializer } from '@complycloud/asn1-der';
import { readFileSync } from 'fs';
// Serialize to DER
const serialize = new DERSerializer();
const asn1Sequence = new Universal.Sequence([
new Universal.Integer(123),
new Universal.PrintableString('Hello World'),
]);
const bufferContainingDEREncodedASN1 = serialize(asn1Sequence);
// Deserialize from PEM
const deserialize = new PEMDeserializer();
const certificate = readFileSync('/path/to/some/certificate.pem', 'utf8');
const certificateASN1 = deserialize(certificate);Debugging
This library uses the @complyify/debug library for debugging. To enable debug messages, simply set the DEBUG
environment variable.
# enable all debugging messages in this library
