This pull request introduces a new class that implements the PKCS7 padding algorithm. The class provides three main methods:
AddPadding
,RemovePadding
, andGetPaddingSize
.AddPadding
: This method adds padding to the end of a byte array according to the PKCS#7 standard.RemovePadding
: This method removes the PKCS7 padding from the given input data.GetPaddingSize
: This method gets the number of padding bytes in the given input data according to the PKCS7 padding scheme.The implementation uses bitwise operations to avoid branching, which can lead to more efficient code execution,and avoid timing attacks.
In addition, a new folder structure Crypto/Padding has been created for this implementation, as the current structure didn’t have any relevant folder for this implementation.
