  65. .SH DESCRIPTION
  66. .IX Header "DESCRIPTION"
  67. Support for a NULL digest through the \fBEVP_MD\fR API.
  68. This algorithm does nothing and returns 1 for its init,
  69. update and final methods.
  70. .SS "Algorithm Name"
  71. .IX Subsection "Algorithm Name"
  72. The following algorithm is available in the default provider:
  73. .IP """NULL""" 4
  74. .IX Item """NULL"""
  75. .SS "Gettable Parameters"
  76. .IX Subsection "Gettable Parameters"
  77. This implementation supports the common gettable parameters described
  78. in \fBEVP_MD\-common\fR\|(7).
