Blowfish Cipher uses 16 rounds of encryption to ensure high security. The algorithm divides the data into blocks and each block undergoes 16 iterations for encryption or decryption. This multi-round approach enhances the complexity of the cipher, making it difficult for attackers to decipher the original message without the correct key. Each round uses different subkeys derived from the main key, adding another layer of protection. Furthermore, Blowfish’s design allows changes in one part of the plaintext or key to affect every bit of the ciphertext, a property known as avalanche effect, which further increases its resistance against attacks.
