crypto_primitives_bench

Criterion-driven microbenchmarks for the cryptographic primitives client/wallet code uses on every transaction. No live sequencer or Bedrock needed.

Run

cargo bench -p crypto_primitives_bench --bench primitives

What you'll see

Criterion's per-operation report (point estimate, 95% CI, outlier counts) for:

• keychain/new_os_random: full mnemonic → SSK → NSK/VSK + public-key derivation (HMAC-SHA512 PBKDF dominates).
• keychain/new_mnemonic: same pipeline, mnemonic exposed.
• shared_secret_key/sender_dh: secp256k1 ECDH per recipient (includes ephemeral key gen).
• encryption/encrypt / decrypt: ChaCha20 over an Account note.

Per-bench JSON estimates are written under target/criterion/<group>/<bench>/. HTML reports at target/criterion/report/index.html.
