.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBEVP_set_default_properties()\fR sets the default properties for all
future \s-1EVP\s0 algorithm fetches, implicit as well as explicit. See
\&\*(L"\s-1ALGORITHM FETCHING\*(R"\s0 in \fBcrypto\fR\|(7) for information about implicit and explicit
fetching.
.PP
EVP_set_default_properties stores the properties given with the string
\&\fIpropq\fR among the \s-1EVP\s0 data that's been stored in the library context
given with \fIlibctx\fR (\s-1NULL\s0 signifies the default library context).
.PP
Any previous default property for the specified library context will
be dropped.
.PP
\&\fBEVP_default_properties_enable_fips()\fR sets the 'fips=yes' to be a default property
if \fIenable\fR is non zero, otherwise it clears 'fips' from the default property
query for the given \fIlibctx\fR. It merges the fips default property query with any
existing query strings that have been set via \fBEVP_set_default_properties()\fR.
.PP
\&\fBEVP_default_properties_is_fips_enabled()\fR indicates if 'fips=yes' is a default
property for the given \fIlibctx\fR.
.SH "NOTES"
.IX Header "NOTES"
\&\fBEVP_set_default_properties()\fR and  \fBEVP_default_properties_enable_fips()\fR are not
thread safe. They are intended to be called only during the initialisation
phase of a \fIlibctx\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBEVP_set_default_properties()\fR and  \fBEVP_default_properties_enable_fips()\fR return 1
on success, or 0 on failure. An error is placed on the error stack if a
failure occurs.
.PP
\&\fBEVP_default_properties_is_fips_enabled()\fR returns 1 if the 'fips=yes' default
property is set for the given \fIlibctx\fR, otherwise it returns 0.
