In cryptographic circles, plaintext is the message we are trying to transmit. The process of encryption converts that plaintext message into ciphertext, and decryption converts the ciphertext back into plaintext. Encryption algorithms are technically classified in two broad categories- Symmetric key Cryptography and Asymmetric Key Cryptography. In symmetric type of Cryptography, the key that is used for encryption is same as the key used in decryption. Examples of various symmetric key algorithms are Data encryption standard (DES), Triple DES, Advanced Encryption Standard (AES) and Blowfish Encryption Algorithm. In Asymmetric Cryptography, two unique keys are used for encryption and decryption. One is public and the other one is private. Examples of various Asymmetric key algorithms are Elliptic-curve cryptography (ECC), Diffie–Hellman key exchange, Rivest-Shamir-Adleman (RSA), etc. Overview of blowfish Algorithm Blowfish is another algorithm designed by Bruce Schneier in 1993 to replace DES. This symmetric cipher splits messages into blocks of 64 bits and encrypts them individually. Blowfish can be found in software categories ranging from e-commerce platforms for securing payments to password management tools, where it used to protect passwords. It’s definitely one of the more flexible encryption methods available. Blowfish is a symmetric block cipher that can be used as…
