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
'1000101' '1111000' '1100001' '1101101' '1110000' '1101100' '1100101' '0111010' '0100000' '1100011' '1101111' '1101110' '1110110' '1100101' '1110010' '1110100' '1101001' '1101110' '1100111' '0100000' '1100011' '1101000' '1100001' '1110010' '0100000' '1110110' '1100101' '1100011' '1110100' '1101111' '1110010' '0100000' '1110100' '1101111' '0100000' '1100010' '1101001' '1101110' '1100001' '1110010' '1111001' '0101110'

The transpose (bin') is important to include.
singleLine = reshape(bin',1,[])
