WebBlowfish's use of a 64-bit block size (as opposed to e.g. AES's 128-bit block size) makes it vulnerable to birthday attacks, particularly in contexts like HTTPS. In 2016, the SWEET32 attack demonstrated how to leverage birthday attacks to perform plaintext recovery (i.e. decrypting ciphertext) against ciphers with a 64-bit block size.

WebSep 24, 2024 · The birthday attack finds two different messages m₁, m₂, such that H (m₁) = H (m₂), namely a hash collision between two messages. This is where the birthday … WebThat means it takes about 2 n − 1 tries on average to find a colliding message y for a given message x so that H ( y) = H ( x) while y ≠ x. However, a birthday attack (e.g. both x and y can be selected arbitrarily, but H ( x) = H ( y) is of course still required) is supposed to be much faster, and take only 2 n / 2 tries to find a collision.
