string getFileMD5Sum(string filepath)

The function computes MD5 digest for the file (with the dmd compiler it works extremely inefficiently).

string getFileStreebogSum(alias bits)(string filepath) 
if(bits == 256 || bits == 512)

The function computes Streebog hash sum for the file.

string getFileStreebog256Sum(string filepath)

256-bit version of file Streebog hash sum.

string getFileStreebog512Sum(string filepath)

512-bit version of file Streebog hash sum.

ubyte[64] modulo512(in ubyte[64] a, in ubyte[64] b)

Auxiliary function of the remainder of the division for the Streebog algorithm.

ubyte[64] xor512(in ubyte[64] a, in ubyte[64] b)

Auxiliary XOR-function for the Streebog algorithm.
