Add baremetal _nostd variant am: 7944c99fec Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/der/+/2769731 Change-Id: Ice1f5de37b67ddef005e1806f4fa7be868487532 Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
Pure Rust embedded-friendly implementation of the Distinguished Encoding Rules (DER) for Abstract Syntax Notation One (ASN.1) as described in ITU X.690.
This crate provides a no_std
-friendly implementation of a subset of ASN.1 DER necessary for decoding/encoding the following cryptography-related formats implemented as crates maintained by the RustCrypto project:
pkcs1
: RSA Cryptography Specificationspkcs5
: Password-Based Cryptography Specificationpkcs7
: Cryptographic Message Syntaxpkcs8
: Private-Key Information Syntax Specificationpkcs10
: Certification Request Syntax Specificationsec1
: Elliptic Curve Cryptographyspki
: X.509 Subject Public Key Infox501
: Directory Services Typesx509
: Public Key Infrastructure CertificateThe core implementation avoids any heap usage (with convenience methods that allocate gated under the off-by-default alloc
feature).
The DER decoder in this crate performs checks to ensure that the input document is in canonical form, and will return errors if non-canonical productions are encountered. There is currently no way to disable these checks.

We may change the MSRV in the future, but it will be accompanied by a minor version bump.
