AX 2012 - Calculating the hash Value of a string in X++ code

There is infinite number of ways how to compute a hash and, of course, different implementations and different hash algorithms have different properties. Below code is the most simplest code for generating a hash value of a string in SHA-256. you can update this code and provide your own hashing algorithm by editing the below line with the list of available hashing algorithm in MSDN.

System.Security.Cryptography.SHA512::Create();

Hashing Function:

public str CalculateHash(str tb)

{

    str s;

    ClrObject obj;

    ClrObject SHA256;

    System.Text.StringBuilder sBuilder;

    ClrObject clrStr;

    ClrObject clrStrObject;

    System.Exception clrException;

    System.Array resultByteArray;

    int i;

    int arrayLength ;

    InteropPermission perm;

    perm = new InteropPermission(InteropKind::ClrInterop);

    perm.assert();

    try

    {

        obj = System.Text.Encoding::get_ASCII().GetBytes(tb);

        SHA256 = System.Security.Cryptography.SHA512::Create();

        resultByteArray = SHA256.ComputeHash(obj);

        //BP deviation documented

        sBuilder = new System.Text.StringBuilder();

        arrayLength = resultByteArray.get_Length() ;

        // Loop through each byte of the hashed data

        // and format each one as a hexadecimal string.

        for (i = 0; i <arrayLength; i++)

        {

            clrStrObject = resultByteArray.GetValue(i);

            clrStr = clrStrObject.ToString('x2');

            sBuilder.Append(clrStr);

        }

        // Return the hexadecimal string.

        s = sBuilder.ToString();

    }

    catch (Exception::CLRError)

    {

        //BP deviation documented

        clrException = CLRInterop::getLastException();

        s = clrException.get_Message();

        error(s);

        throw error("@SYS106158");

    }

    CodeAccessPermission::revertAssert();

    return s;
