What is the block size used with the Skipjack cipher?

The Skipjack cipher uses a block size of 64 bits. This means that the algorithm processes data in chunks of 64 bits at a time during both encryption and decryption. The design of Skipjack, developed by the National Security Agency (NSA), was specifically created for secure communications and is known for its unique keys and operational structure. The choice of a 64-bit block size is significant as it reflects the technology and cryptographic standards of the time when it was developed, aligning with other ciphers from that era, such as DES (Data Encryption Standard), which also utilizes a 64-bit block size. Understanding block sizes is crucial in cryptography, as they can impact the security and efficiency of the encryption process.
