Zero after decimal while creating SHA-256 hash

I was creating SHA-256 hash, is it necessary to write zero after decimal. when I create hash with not mentioning zeros after decimal like (only 11), it works but if I create hash with mentioning zeros after a integer like “11.00”, it’s not working resulting signature invalid.

Image case 1(not working with hash signature with zero as decimals)

Hi @anishkandel100

I’m not that knowledgeable about cryptography but I would guess this is due to the number being a floating point.

There can be discrepancies with rounding and this could be what is causing your hash to fail.

There is a good write-up here that might help explain;
