string digestToString(size_t num)(in ubyte[num] digest)
{
    auto result = new char[num*2];
    size_t i;

    foreach(u; digest)
    {
        result[i++] = std.ascii.hexDigits[u >> 4];
        result[i++] = std.ascii.hexDigits[u & 15];
    }
    return assumeUnique(result);
}

adapted from std.md5. I don't really like the name though ;-)
