constant-time-analysis

Constant-time programming prevents timing attacks by eliminating variable-time instructions. It is needed for cryptographic code because execution time variations can leak secret data, allowing attackers to recover encryption keys by measuring operation durations.

Detect timing side-channel vulnerabilities by analyzing compiled assembly or virtual machine bytecode for dangerous operations like variable-time division and secret-dependent branches. This Skill scans multiple programming languages to identify these timing leaks automatically.

Yes, this timing attack analysis supports Python, JavaScript, TypeScript, Swift, and other languages including C, C++, Go, Rust, PHP, Ruby, Java, and Kotlin by examining their compiled assembly or virtual machine bytecode.

Fix variable-time division and secret-dependent branches by applying constant-time programming patterns. This Skill provides specific guidance and patterns for implementing secure solutions to replace dangerous instructions identified during the assembly or bytecode analysis.

Yes, you can use this to review a new encryption function for timing leaks. It automatically scans the cryptographic code to detect any operations that might leak the secret key through execution timing differences, ensuring secure implementation.
