Crate tsumiki_asn1 

tsumiki-asn1

ASN.1 (Abstract Syntax Notation One) data structure representation.

This crate implements ASN.1 types as defined in ITU-T X.680.

Supported Types

• Primitive types: INTEGER, BOOLEAN, NULL, OCTET STRING, BIT STRING
• String types: UTF8String, PrintableString, IA5String, BMPString
• Time types: UTCTime, GeneralizedTime
• Structured types: SEQUENCE, SET
• Object identifiers: OBJECT IDENTIFIER
• Context-specific types

Example

use tsumiki::decoder::Decoder;
use tsumiki_der::Der;
use tsumiki_asn1::ASN1Object;

// DER bytes for SEQUENCE { INTEGER 42 }
let bytes = vec![0x30, 0x03, 0x02, 0x01, 0x2a];

// Parse DER to ASN.1
let der: Der = bytes.decode()?;
let asn1: ASN1Object = der.decode()?;

assert_eq!(asn1.elements().len(), 1);
