= Padding oracle attack
{wiki=Padding_oracle_attack}
A Padding Oracle Attack is a type of cryptographic attack that targets block ciphers that use padding schemes to accommodate plaintexts that are not a multiple of the block size. This type of attack exploits the way certain cryptographic systems handle incorrect padding, allowing an attacker to decrypt ciphertext without knowing the encryption key. \#\#\# How It Works 1. **Block Ciphers and Padding**: Block ciphers like AES or DES encrypt data in fixed-size blocks.
