What makes a good encryption algorithm

The algorithm uses a bit individual key with the total key length adding up to bits. However, since it is consecutive encryption, there is a middle-level vulnerability that decreases its protection to the level of a bit key. Because of the complexity in the way it works, the Triple DES encryption is slower, but still, its effectiveness is good enough to keep it as one of the approved data encryption algorithms till It is also slowly phased out and used for its dependability in financial services and other industries as a hardware encryption solution.

Named after its creators, the Rivest-Sharmir-Adleman RSA is established as the standard public-key encryption algorithm. It is asymmetric because it has a public and a private key that encrypts data being sent and received. Its scrambling level takes far too much time for any attackers to break and keeps communication quite secure. The keys for the RSA algorithms are generated by multiplying the large number and creating a modulus. However, the bit keys are recommended by the government and IT industry.

Blowfish is symmetrical encryption similar to the DES and hence is known for its high speed. The algorithm breaks data being sent into chunks that are 64 bits and encrypts each individually. The length of the keys can be anywhere from 32 bits to bits, and so far the encryption has never been defeated. What adds to its popularity is that the algorithm is not patented and free for everyone to use in the public domain. It is used by many in industries such as software and e-commerce platforms that need to secure payments and manage passwords.

Twofish is the successor of Blowfish and is also a symmetric encryption method that is favorite among many. Similar to its predecessor, Twofish uses block encrypting and splits the data into blocks that are bits long, and the key is applied simultaneously to all blocks. The key for the encryption can be bits long. It is popularly used with devices that have low processing recourses while brute-forcing the encrypted message of Twofish considered impractical.

Now that we have gone through the types of data encryption techniques, let us next learn the specific encryption algorithms.
