risc0-crypto workspace

R0VM-accelerated cryptography for RISC Zero guest programs.

Crates

risc0-crypto - primitives library: short Weierstrass curves, prime field arithmetic (Fp256, Fp384), ECDSA, and 256/384/4096-bit modular exponentiation. Uses fewer cycles than the risc0-patched upstream crates.
risc0-crypto-evm - thin EVM-ABI wrappers over the primitives (EIP-196 BN254 add/mul, EIP-198 modexp, EIP-7951 P-256 verify, ecrecover, SHA-256). Consumed by zeth and kailua - no revm dependency so it never blocks a revm upgrade.

See crates/crypto/README.md for the library walkthrough, benchmark numbers, and usage examples.

bench/ is its own workspace (pulls in risc0-zkvm client + the RISC-V guest build tooling). Run locally with rzup r0vm installed:

cargo run --release --manifest-path bench/Cargo.toml
