The following code procedure bytes = parseHexString (createHexString (bytes)) leads to updated of bytes, what I would like to avoid. And as a result calculations are not correct.

I am not javascript developer, and not one found in google code did not work on this data.
Update 1
console.log(createHexString(rsa_privk[0])); = e5d109c673d8ef03df564beb9e36e9983a23842b0a724efa45ff76bbe5ad72ed62d2757968
But if do
parseHexString('e5d109c673d8ef03df564beb9e36e9983a23842b0a724efa45ff76bbe5ad72ed??62d2757968');
then code if (sid!== ... make error
Update 2
console.log(rsa_privk[0].toString(16));
output:

Update 3
console.log(parseHexString(createHexString(rsa_privk[0])));
console.log(rsa_privk[0]);
output:
