how to convert md5 hash value as binary bits?

Hi,

Suppose hash string is YuRtBM.. (something like this), i need it as 000101010 (128 bits because its md5).

any answer for this problem my friend ?

"(something like this)" is not enough to define the input uniquely. Maybe this is base64?

With the bold guess, that the input is a base64 string:

Out  = matlab.net.base64decode('YuRtBM');
Bmat = dec2bin(Out);
Bvec = reshape(Bmat.', 1, []) - '0'

% i find something better than that i gues 
hash = 'dc1c320defa535b9d8177fc07ace6481';
%there are 32 chars on hex ==> 2 chars for 1 element . 
% ==> we use that and it will give you directly the 128 bits : 
binary_hash = hexToBinaryVector(hash);
disp(binary_hash); 
% and you will notice it .

In the original question the hash was "YuRtBM..." which is not a hex string.

hexToBinaryVector is part of the Sata Acquisition Toolbox. Without it:

hash = 'dc1c320defa535b9d8177fc07ace6481';
hexToBin(hash)

function bin = hexToBin(hex)
dec = sscanf(hex, '%2x').';
bin = rem(floor(dec ./ pow2(7:-1:0).'), 2);  % Auto-expand, >= R2016b
bin = reshape(bin, 1, []);
end
