What is a brute force attack?
Tuesday, 30 January 2024
by Laurent Marion
Brute force is a technique used in cybersecurity to crack encrypted messages or passwords by systematically trying all possible combinations until the correct one is found. This method relies on the assumption that the encryption algorithm used is known, but the key or password is unknown. In the field of classical cryptography, brute force attacks

The Advanced Encryption Standard (AES) is a widely-used symmetric block cipher that provides secure encryption for various applications. The security of AES is influenced by two key factors: the key size and the number of rounds. The key size in AES refers to the length of the secret key used for encryption and decryption. AES
