The language of that Declaration has been written into the constitution of a number of states . Ciphers also may operate in a variety of modes , such as Electronic Codebook ( ECB ) , where each block of plain text is simply encrypted with the key , and Cipher Block Chaining ( CBC ) , where the previously encrypted block is fed into the encryption of the next block . Because literacy depends on information , and because information is expanding at exponential rates , the mere ability to read and to write is being translated into the ability to read , write , and to develop the capacities to understand , absorb , assimilate , and digest the images being transmitted electronically with the added capacity to communicate these images electrographically ( Ross Tweed & Bailey , 1994 ) .
