constant-time-testing

Detect timing leaks in cryptographic implementations by running combined static, dynamic, and statistical analysis using tools like ct-verif, dudect, and Timecop to identify secret-dependent branches and validate constant-time behavior.

Constant-time analysis verifies that cryptographic code execution time remains independent of secret data. You need it when auditing crypto libraries, reviewing modular exponentiation, or securing post-quantum operations to prevent timing side-channel attacks.

Yes, dudect and Timecop perform dynamic and statistical analysis to detect timing leaks in real implementations, enabling cross-architecture verification of constant-time behavior across different compilers and platforms.

Audit RSA and ECDH primitives for timing side-channels by applying formal verification with ct-verif to prove constant-time properties on abstracted code, combined with practical dynamic analysis workflows.

Yes, ct-verif supports formal verification to prove constant-time properties on abstracted code, making it suitable for securing post-quantum cryptographic operations against timing side-channel leaks.

Cryptographic code fails constant-time checks with Memsan when dynamic analysis detects secret-dependent memory access patterns or timing variations, indicating potential side-channel leaks that require code hardening.
