.SH NAME
EVP_CIPHER\-NULL \- The NULL EVP_CIPHER implementation
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Support for a NULL symmetric encryption using the \fBEVP_CIPHER\fR API.
This is used when the TLS cipher suite is TLS_NULL_WITH_NULL_NULL.
This does no encryption (just copies the data) and has a mac size of zero.
.SS "Algorithm Name"
.IX Subsection "Algorithm Name"
The following algorithm is available in the default provider:
.IP """NULL""" 4
.IX Item """NULL"""
.SS Parameters
.IX Subsection "Parameters"
This implementation supports the following parameters:
