Speedcrypt Self-Test of Algorithms |
✒️ Self Test Module
The Self-Test module represents a fundamental engineering component within Speedcrypt, designed to ensure the reliability, consistency, and operational integrity of the entire system. At startup, Speedcrypt performs an automatic and structured diagnostic process that validates all core cryptographic components, including encryption engines, hash functions, and HMAC-based constructions. This validation is not generic, but directly tied to the actual implementations used within the system.
The current architecture executes 44 distinct tests, covering a wide range of cryptographic primitives. Despite the breadth of coverage, the execution time remains extremely efficient, typically completing within a few seconds. This performance is the result of careful optimization and a streamlined execution pipeline, ensuring that the startup phase is not negatively impacted while still providing a comprehensive verification layer.
🔧Test Architecture
Each test is executed through a standardized interface, ensuring uniform behavior and consistent validation logic across all cryptographic components.
The system verifies:
- Symmetric encryption algorithms (AES, Serpent, Twofish, Camellia, GOST, Kuznyechik, ChaCha20-Poly1305, Threefish variants)
- Cryptographic hash functions (SHA family, SHA-3, BLAKE family, RIPEMD, Whirlpool, Keccak, Skein, SM3, GOST variants)
- Key derivation and strengthening functions (PBKDF2, Argon2, Scrypt, Bcrypt)
- HMAC constructions based on multiple hash algorithms
Each test produces a deterministic result that is evaluated at runtime. Any deviation, exception, or inconsistency is immediately classified as a failure.
📳 Execution Model
The Self-Test module follows a strictly controlled execution flow:
- Tests are executed sequentially to ensure deterministic behavior
- Each test is individually timed using high-resolution timers
- Results are recorded and displayed in real time
- A global status flag tracks whether all tests have passed
The system is designed so that a single failure is sufficient to mark the entire validation process as compromised.
👀 Result Visualization
All test results are displayed within the user interface through a structured and highly readable format.
For each test, the following information is provided:
- Cryptographic component name
- Test result (PASSED / FAILED)
- Execution time (in milliseconds or seconds)
Visual indicators improve readability:
- Green color for successful tests
- Red color for failed tests
- Blue-toned timing information for performance metrics
Additionally, a final aggregated entry reports the total execution time of the entire test suite, providing a clear overview of system performance.
🚀 Runtime Integration
The Self-Test module is fully integrated into the application lifecycle:
- Automatically executed at startup
- Manually executable at any time via the Self-Test [CTRL+L] command
- Progress is tracked through a real-time progress indicator
This allows users to revalidate system integrity after:
- Configuration changes
- Software updates
- Extended runtime sessions
- Environmental variations
🖊️Engineering Purpose
From an engineering standpoint, the Self-Test module serves multiple critical objectives:
🪛 Early Fault Detection
Any malfunction, inconsistency, or unexpected behavior is immediately identified, preventing the system from operating under unreliable conditions.

🖊️Design Considerations
The Self-Test module is intentionally designed to be:
- Deterministic
- Lightweight
- Non-intrusive
- Fully repeatable
It does not rely on external conditions and operates entirely within a controlled execution environment, ensuring consistent and reliable results across different systems.
🖊️Engineering Conclusion
The Self-Test module is not merely a diagnostic feature, but a core component of the Speedcrypt security model. By continuously validating its own cryptographic foundation, Speedcrypt ensures that every operation is executed within a trusted and verified environment. This transforms the system from a passive execution platform into an active self-verifying architecture, where reliability is not assumed, but constantly proven through systematic validation.
Periodic execution of the Self-Test is recommended to ensure continuous verification of algorithm integrity, especially across different systems or after environmental and configuration changes!
