=head1 NAME
EVP_set_default_properties, EVP_default_properties_enable_fips,
- Set default properties for future algorithm fetches
#include <openssl/evp.h>
int EVP_set_default_properties(OSSL_LIB_CTX *libctx, const char *propq);
int EVP_default_properties_enable_fips(OSSL_LIB_CTX *libctx, int enable);
int EVP_default_properties_is_fips_enabled(OSSL_LIB_CTX *libctx);
EVP_set_default_properties() sets the default properties for all
future EVP algorithm fetches, implicit as well as explicit. See
L<crypto(7)/ALGORITHM FETCHING> for information about implicit and explicit
EVP_set_default_properties stores the properties given with the string
I<propq> among the EVP data that's been stored in the library context
given with I<libctx> (NULL signifies the default library context).
Any previous default property for the specified library context will
be dropped.
EVP_default_properties_enable_fips() sets the 'fips=yes' to be a default property
if I<enable> is non zero, otherwise it clears 'fips' from the default property
query for the given I<libctx>. It merges the fips default property query with any
existing query strings that have been set via EVP_set_default_properties().
EVP_default_properties_is_fips_enabled() indicates if 'fips=yes' is a default
property for the given I<libctx>.
EVP_set_default_properties() and EVP_default_properties_enable_fips() return 1
on success, or 0 on failure. An error is placed on the error stack if a
failure occurs.
EVP_default_properties_is_fips_enabled() returns 1 if the 'fips=yes' default
property is set for the given I<libctx>, otherwise it returns 0.
