  66             Use SHA-1 as the digest algorithm (the default is to use

  75             Select the digest algorithm. The value of
  76             <code class="option">algorithm</code> must be one of SHA-1 (SHA1),
  77             SHA-256 (SHA256), GOST or SHA-384 (SHA384).
  78             These values are case insensitive.
