asn1lib 0.5.3 asn1lib: ^0.5.3 copied to clipboard
An ASN1 parser library for Dart. Encodes / decodes from ASN1 Objects to BER bytes
An ASN.1 Parser for Dart.
Encodes & decodes ASN1 using BER encoding.
There is just enough implementation here to get an LDAP client library working.
Sample
var s = new ASN1Sequence();
s.add( new ASN1Integer(23));
s.add( new ASN1OctetString('This is a test'));
s.add( new ASN1Boolean(true));
// GET the BER Stream
var bytes = s.encodedBytes;
// decode
var p = new ASN1Parser(bytes);
var s2 = p.nextObject();
// s2 is a sequence...
