Please,

How to convert like this ( plaintext = 'wireless sensor networks, using lightweight cryptography in WSNs to provide security' ); each letter converte's to it's corresponding binary bits.

all the text to a string of bits and then I can split it to a sequence of (64-bit) block, each 64-bit use it as input Binary for cryptography algorithm?

appreciate your response

Looking for dec2bin?

charvec = 'Example: converting char vector to binary.';
bin = dec2bin(charvec)
bin = 42×7 char array

Thanks for your response, that's what I did exactly,

but how can I merge all (7-bit) that represnt characters in one (bit stream) in order to process it as a block.

for Example (1X294) cell

'100010111110001100001110110111100001101100 ....'

thanks a lot,

greetings

The transpose (bin') is important to include.

singleLine = reshape(bin',1,[])
