rust-asn1

This is a Rust library for parsing and generating ASN.1 data (DER only).

Installation

Add asn1 to the [dependencies] section of your Cargo.toml:

[dependencies]
asn1 = "0.18"

Builds on Rust 1.59.0 and newer.

rust-asn1 is compatible with #![no_std] environments:

asn1 = { version = "0.18", default-features = false }

GeneralizedTime has been renamed to X509GeneralizedTime. The type does not allow fractional seconds, however this restriction is not actually a DER rule, it is specific to X.509. (#494)
GeneralizedTime is a new type that accepts fractional seconds replacing the old GeneralizedTime. (#492)
