Package Exports
- @ldapjs/asn1
- @ldapjs/asn1/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ldapjs/asn1) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
@ldapjs/asn1
@ldapjs/asn1 is a library for encoding and decoding ASN.1 datatypes in pure
JS. Currently BER encoding is supported.
Decoding
The following reads an ASN.1 sequence with a boolean.
const { BerReader, BerTypes } = require('@ldapjs/asn1')
const reader = new BerReader(Buffer.from([0x30, 0x03, 0x01, 0x01, 0xff]))
reader.readSequence()
console.log('Sequence len: ' + reader.length)
if (reader.peek() === BerTypes.Boolean)
console.log(reader.readBoolean())Encoding
The following generates the same payload as above.
const { BerWriter } = require('@ldapjs/asn1');
const writer = new BerWriter();
writer.startSequence();
writer.writeBoolean(true);
writer.endSequence();
console.log(writer.buffer);Installation
npm install @ldapjs/asn1
