C++ pretty output of SHA 256

I'm facing a problem and I don't know how I can solve it / I don't know where to search.

I'm using botan to generate a SHA-256 check sum and I want it to output it as (I think) modhex.

Though, the output is like:

Code:

L�y�����B��Fs!�)�v&�VG

The output should be something like:

Code:

b8ed91da716fc576e3d005d91a9bdab842288439

I tried using:

Code:

cout << setbase(16) << sha256str << endl;

But it doesn't make a difference at all.

What can I do or what should I know?

I should've read more of the Botan documentation. Something like:

Code:

Botan::Pipe pipe(new Botan::Hex_Encoder);

Can convert the output to hexadecimal output.

Now, I wonder, what's the output format of the sha1sum application?
