Add baremetal _nostd variant Note that product_available and vendor_available are dropped from the existing target because they are irrelevant for a _host target (as per the change in aosp/2763825). Add a visibility restriction to the new variant to preserve the limitation that this crate should not be used in general Android code. Bug: 303192701 Test: build both variants Change-Id: Ib9f3a7b59d8c3549f23c9590a324240dbbb3860a
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.
