P-Signature Cryptography

P-Signature System

Key Management

The key is fundamental for security. Recommendations:

Minimum 12 characters
Mix of letters, numbers and symbols
Avoid common words
The same key must be used for encryption and decryption

Complete Interactive Tests

ℹ️ These tests allow you to manually verify all system functionalities.

Test 1: Determinism

Verifies that the same text with the same key always produces the same signature. The system must be deterministic to ensure reproducibility.
