Length extension attack
ATTACK AGAINST CRYPTOGRAPHICAL HASH FUNCTIONS, WHERE KNOWING HASH(MESSAGE₁) AND THE LENGTH OF MESSAGE₁ ALLOWS AN ATTACKER TO CALCULATE HASH(MESSAGE₁ ‖ MESSAGE₂) FOR AN ATTACKER-CONTROLLED MESSAGE₂
Hash length extension attack; Length-extension; Length extension
In cryptography and computer security, a length extension attack is a type of attack where an attacker can use Hash(message1) and the length of message1 to calculate Hash(message1 ‖ message2) for an attacker-controlled message2, without needing to know the content of message1. Algorithms like MD5, SHA-1 and most of SHA-2 that are based on the Merkle–Damgård construction are susceptible to this kind of attack.
