448 bits. Encryption in Blowfish algorithm involves 16-round Feistel cipher, using large key-dependent S-boxes.One drawback of the Blowfish algorithm is that it is vulnerable to birthday attacks, especially in contexts like HTTPS. Apart from that, it is apparent that Blowfish is ineffective in encrypting files larger than 4 GB due to its small 64-bit block size.What are some of the popular Blowfish uses? You can find the encryption algorithm in various software categories, specifically database security, eCommerce platforms, file and disk encryption, and archiving tools. Blowfish is also efficient in password management, file transfer, secure shell, steganography, and email encryption. 6. TwofishBruce Schneier created the Twofish symmetric cipher algorithm to replace the less secure Blowfish algorithm. Twofish used the Situation Box (S-box) as part of its encryption method. Twofish uses a 128-bit block size and supports a key size of up to 256 bits, making it secure from brute force attacks. One-half of the n-bit key represents the encryption key, while the second half modifies the encryption algorithm.Twofish is slightly slower than AES but comparatively faster for 256-bit keys. On top of that, the algorithm is flexible, making it ideal for use in network apps where keys change frequently. Moreover, Twofish is efficient in systems where only a small amount of RAM and ROM is available for use. More frequently, the algorithm comes bundled in encryption tools like TrueCrypt, GPG, and PhotoEncrypt.7. AESAES – Advanced Encryption Standard acronym, technology concept backgroundThe Advanced Encryption Standard (AES) is the successor of DES. NIST initiated a public four-and-a-half-year process to develop a new secure cryptosystem for U.S. government applications in 1997. This development opposed the very closed process in the adoption of DES more than two decades earlier. The result of the process was AES, which became the official DES successor in December 2001. AES algorithm is a block cipher that features three sizes: AES-128, AES-192, and AES-256. AES encryption algorithm puts data into an array before performing a series of transformations known as rounds. Essentially, AES is exceptionally efficient in 128-bit form. It can also leverage 192 and 256-bits keys for heavy security. It operates ten rounds for 128-bit keys and 12 rounds for 192-bit keys. The 235-bit key has 14 rounds. Also, the algorithm uses secret-key cryptography known as Rijndael, a block cipher designed by Belgian cryptographers Joan Daemen and Vincent Rijmen. By design, the AES algorithm is sufficient to protect government secrets and sensitive corporate information. It is naturally secure, and security analysts have not discovered any practical attacks against the algorithm. Accordingly, the encryption algorithm has become a trusted standard for the United States Government and various organizations.Notably, AES has low RAM requirements and high speed, qualifying it as
