Excited to use the new `hybrid-array` crate from @RustCryptoOrg ! It's like `generic-array` but with no `unsafe` under the hood, a bridge to using fully-featured const generics in expressions in the not-too-distant Rust future! docs.rs/hybrid-array crates.io/crates/hybrid-arra…

Our `ecdsa` crate prevents vulnerabilities like Java's CVE-2022-21449 using type safety. We use a `NonZeroScalar` type to model the `r` and `s` components of an ECDSA signature. This prevents either of them from ever accidentally being zero. docs.rs/ecdsa/0.13.4/ecdsa/s…

My sha1 crate is now called sha1_smol for when you need a dependency free version. Major versions of the sha1 crate in the future will refer to the RustCrypto SHA1 implementation. Users of the 0.6 line of sha1 are auto migrated to sha1_smol. github.com/mitsuhiko/sha1-sm…

In a moment of serendipity I just so happen to have published a new @RustCryptoOrg strict PEM parser which not only uses a constant time Base64 implementation but in the happy path completely avoids any branching or table lookups on potentially secret data github.com/RustCrypto/utils/…

Likewise, we use constant-time scalar inversions for ECDSA verification, where variable-time inversions could potentially be faster.
