node-asn1 is a library for encoding and decoding ASN.1 datatypes in pure JS.
Currently BER encoding is supported; at some point I'll likely have to do DER.
## Usage
Mostly, if you're *actually* needing to read and write ASN.1, you probably don't
need this readme to explain what and why. If you have no idea what ASN.1 is,
see this: ftp://ftp.rsa.com/pub/pkcs/ascii/layman.asc
The source is pretty much self-explanatory, and has read/write methods for the
common types out there.
### Decoding
The following reads an ASN.1 sequence with a boolean.
var Ber = require('asn1').Ber;
var reader = new Ber.Reader(Buffer.from([0x30, 0x03, 0x01, 0x01, 0xff]));
reader.readSequence();
console.log('Sequence len: ' + reader.length);
if (reader.peek() === Ber.Boolean)
console.log(reader.readBoolean());
### Encoding
The following generates the same payload as above.
var Ber = require('asn1').Ber;
var writer = new Ber.Writer();
writer.startSequence();
writer.writeBoolean(true);
writer.endSequence();
console.log(writer.buffer);
## Installation
npm install asn1
## License
MIT.
## Bugs
See <https://github.com/joyent/node-asn1/issues>.
