Pure Rust embedded-friendly implementation of the Distinguished Encoding Rules
(DER) for Abstract Syntax Notation One (ASN.1) as described in ITU X.690 with
full support for heapless no_std targets
base64ct • 1.6.0Pure Rust implementation of Base64 (RFC 4648) which avoids any usages of
data-dependent branches/LUTs and thereby provides portable "best effort"
constant-time operation and embedded-friendly no_std support
bitflags • 1.3.2A macro to generate structures which behave like bitflags.

bitflags • 2.6.0A macro to generate structures which behave like bitflags.

cfg-if • 1.0.0A macro to ergonomically define an item depending on a large number of #[cfg]
parameters. Structured like an if-else chain, the first matching branch is the
item that gets emitted.

const-oid • 0.9.6Const-friendly implementation of the ISO/IEC Object Identifier (OID) standard
as defined in ITU X.660, with support for BER/DER encoding/decoding as well as
heapless no_std (i.e. embedded) support

der_derive • 0.6.1Custom derive support for the `der` crate's `Choice` and `Sequence` traits

errno • 0.3.9Cross-platform interface to the `errno` variable.
pem-rfc7468 • 0.6.0PEM Encoding (RFC 7468) for PKIX, PKCS, and CMS Structures, implementing a
strict subset of the original Privacy-Enhanced Mail encoding intended
specifically for use with cryptographic keys, certificates, and other messages.
Provides a no_std-friendly, constant-time implementation suitable for use with
cryptographic private keys.
proc-macro2 • 1.0.88A substitute implementation of the compiler's `proc_macro` API to decouple token-based libraries from the procedural macro use case.

proptest • 1.5.0Hypothesis-like property-based testing and shrinking.
zeroize • 1.8.1Securely clear secrets from memory with a simple trait built on
stable Rust primitives which guarantee memory is zeroed using an
operation will not be 'optimized away' by the compiler.
Uses a portable pure Rust implementation that works everywhere,
even WASM!
