​KembaraXtra-Computer Terms – block cipher:
A block cipher is a method of encryption that processes data in fixed-size groups known as blocks. Each block of data, commonly consisting of 64 bits or more, is encrypted using a secret key before being transmitted or stored.
During encryption, the block cipher transforms the original data block into an encrypted version of the same size. This method is widely used in cryptographic systems because it provides strong protection for sensitive information when combined with secure encryption algorithms.
