Wait, so I was talking about SHA-224 which is SHA-256 truncated to 224 bits, not SHA-512 truncated to 224 bits.
Nevertheless, does this mean SHA-224 is still susceptible to length extension attacks?
- nialo 9y agoSHA-256 truncated to 224 bits is vulnerable to length extension attacks if the attacker can brute force the remaining 32 bits of the state. Some use cases will make this possible or practical, some will not. It depends on the details of the problem being solved.
