  10  * Creates a MD5 based hash of a password
  11  *
  12  * To validate a entered password, use the previously calculated
  13  * password hash as salt, and then compare the result. If identical
  14  * then the password matches.
  15  *
  16  * While encoding a password the salt should be 8 randomly selected
  17  * characters from the base64 alphabet, for example generated as follows:
  18  *    char salt[9];
  19  *    to64(salt, rand(), 4);
  20  *    to64(salt+4, rand(), 4);
  21  *    salt[0] = '\0';
