Pure Rust embedded-friendly implementation of the Distinguished Encoding Rules (DER) for Abstract Syntax Notation One (ASN.1) as described in ITU X.690.

Documentation

About

This crate provides a no_std-friendly implementation of a subset of ASN.1 DER necessary for decoding/encoding various cryptography-related formats implemented as part of the RustCrypto project, e.g. the pkcs8 crate.

The core implementation avoids any heap usage (with convenience methods that allocate gated under the off-by-default alloc feature).
