Brute-Force Cryptography Attack 🔑

Brute-Force Attack: In a brute-force attack, an attacker systematically tries all possible combinations of keys or passwords until the correct one is found. This attack can be time-consuming, especially with longer keys or complex passwords, but it can be effective if the key space is small or if weak passwords are used.

Known-Plaintext Attack: In a known-plaintext attack, the attacker has access to both the ciphertext and the corresponding plaintext. By analyzing multiple pairs of known plaintext and ciphertext, the attacker tries to deduce the key or the encryption algorithm used.

Chosen-Plaintext Attack: In a chosen-plaintext attack, the attacker can select and obtain the ciphertext for specific plaintext inputs of their choice. The goal is to use this information to deduce the key or the encryption algorithm.

Cipher Text-Only Attack: In a ciphertext-only attack, the attacker only has access to the encrypted ciphertext and has no knowledge of the corresponding plaintext. The attacker tries to analyze the ciphertext to deduce information about the key or the plaintext.

Man-in-the-Middle (MITM) Attack: In a MITM attack, the attacker intercepts and alters the communication between two parties who are trying to establish a secure connection. The attacker can potentially decrypt, modify, or forge messages exchanged between the two parties.

Side-Channel Attacks: Side-channel attacks exploit information leaked during the execution of a cryptographic algorithm, such as power consumption, electromagnetic radiation, or timing information. By analyzing these side channels, an attacker may gain insights into the secret key used in the encryption.

Birthday Attack: A birthday attack leverages the birthday paradox, which states that in a set of randomly chosen people, the probability of two people having the same birthday is higher than expected. In cryptography, a birthday attack aims to find collisions in hash functions or cryptographic algorithms that produce the same hash or ciphertext for different inputs.

Meet-in-the-Middle Attack: A meet-in-the-middle attack combines a known-plaintext attack with a chosen-plaintext attack. It involves encrypting the known plaintext with all possible keys and then decrypting the chosen ciphertext with all possible keys, looking for a match between the two results.

Differential Cryptanalysis: Differential cryptanalysis is a statistical attack that looks for patterns in pairs of plaintext-ciphertext pairs to deduce information about the key. It focuses on exploiting the differences between plaintext inputs and the corresponding ciphertext outputs.

Adaptive Chosen-Ciphertext Attack (CCA): In a CCA attack, the attacker can obtain the decryption of chosen ciphertexts and adaptively select subsequent ciphertexts based on the information gained. The goal is to obtain the decryption of target ciphertexts or to manipulate the system in some way.
