Crate silentops 

silentops — side-channel countermeasure toolkit

silentops gathers the side-channel building blocks shared by the krypteia workspace (post-quantum crate quantica and classical crate arcana).

Three modules are exposed today:

• ct — constant-time primitives with architecture-specific assembly backends (no_std). This is the former ct_ops crate.
• ct_grind — Valgrind memcheck client-request helpers (poison / unpoison) used to verify constant-time code under valgrind --error-exitcode=1. Emits real instrumentation on x86_64-linux / aarch64-linux when the ct-grind feature is enabled; elsewhere the calls are zero-cost no-ops (no_std).
• [verify] — dudect-style timing leakage detector based on Welch’s t-test (std only). This is the former ct_verify crate, refactored as a reusable library.

Future modules will host additional shared SCA helpers (masking, shuffling, fault-injection countermeasures, …) so that both classical and post-quantum sides reuse the same primitives.

no_std

The crate is no_std by default. The [verify] module is only compiled when the std feature is enabled.

Re-exports

For convenience, all primitives from ct are re-exported at the crate root, so call sites can write silentops::ct_eq(...) instead of silentops::ct::ct_eq(...).

Re-exports

pub use ct::*;
