− An older encryption method which is less secure than AES but still used in some legacy systems. Triple DES (3DES)− It is a more secure version of DES that applies the DES algorithm three times. Blowfish− It is a symmetric-key block cipher which is known for its fast encryption...
Cryptography series: blowfish symmetric key grouping algorithm Introduction Blowfish is a symmetric key block encryption algorithm invented by Bruce Schneier in 1993. Similar DES and AES are block encryption algorithms. Blowfish is used to replace the DES algorithm, and Blowfish has no commercial restric...
