.SH NAME
EVP_MD\-NULL \- The NULL EVP_MD implementation
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Support for a NULL digest through the \fBEVP_MD\fR API.
This algorithm does nothing and returns 1 for its init,
update and final methods.
.SS "Algorithm Name"
.IX Subsection "Algorithm Name"
The following algorithm is available in the default provider:
.IP """NULL""" 4
.IX Item """NULL"""
.SS "Gettable Parameters"
.IX Subsection "Gettable Parameters"
This implementation supports the common gettable parameters described
in \fBEVP_MD\-common\fR\|(7).
