Until the announcement of ORGANIZATION@1 's ORGANIZATION@2 contest , the majority of block ciphers followed the example of the DES in using a block size of NUMBER@1 bits -LRB- NUMBER@2 bytes -RRB- .

The DES is using a block size of NUMBER@1 bits -LRB- NUMBER@2 bytes -RRB- while the ORGANIZATION@2 is using a block size of NUMBER@3 bits -LRB- NUMBER@4 bytes -RRB- .
