Rscrypto

rscrypto v0.2.0 is the 2026-05-17 performance and platform release.

Highlights:

• Published to crates.io as rscrypto 0.2.0.
• Linux CI fastest-external scorecard: 3,807 wins / 6,552 comparisons, 1.52x geomean vs the fastest matched Rust baseline.
• Full current corpus including local Apple Silicon: 4,120 wins / 7,280 fastest-external comparisons, 1.51x geomean.
• Checksums remain the cleanest broad win at 5.10x Linux CI geomean.
• SHA-3 / SHAKE remain strong at 2.17x / 2.60x Linux CI geomean.
• BLAKE3 sustained rows (>=64 KiB) hold at 2.38x Linux CI geomean against the blake3 crate.
• AEAD is broadly positive at 1.37x Linux CI geomean, with GCM-SIV, XChaCha20-Poly1305, AEGIS-256, and IBM Z as the strongest areas.
• SHA-512-family work landed: HMAC-SHA384 and HMAC-SHA512 both sit at 1.23x Linux CI geomean; local Apple Silicon HMAC-SHA512 is 1.02x.

Known pressure points remain visible in the benchmark overview: password hashing, Linux CI Ed25519 verify, X25519, local Apple Silicon Ed25519 signing, and sustained AES-GCM on POWER10/RISC-V.
