Digest.put

void put(scope const(ubyte)[] data...) @trusted nothrow

Use this to feed the digest with data. Also implements the isOutputRange interface for ubyte and const(ubyte)[].

Example:

void test(Digest dig)
{
    dig.put(cast(ubyte) 0); //single ubyte
    dig.put(cast(ubyte) 0, cast(ubyte) 0); //variadic
    ubyte[10] buf;
    dig.put(buf); //buffer
}
