Module crypto::asn1

#include <std/crypto/asn1.h> source

a minimal DER (ASN.1) reader for std's crypto.

std-internal ('' names): the TLV walking x509.h's certificate parser, rsa.h's key parsing and ec.h's signature parsing share. An Asn1 is a view of bytes owned elsewhere; reading a TLV advances it. Definite lengths only (DER), at most four length bytes.
