EVP_set_default_properties, EVP_default_properties_enable_fips,
EVP_default_properties_is_fips_enabled - 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 "ALGORITHM
FETCHING" in
crypto(7) for information about implicit and explicit
fetching.
EVP_set_default_properties stores the properties given with the string
propq among the EVP data that's been stored in the library context
given with
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
enable is non zero, otherwise it clears 'fips' from the
default property query for the given
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
libctx.
EVP_set_default_properties() and
EVP_default_properties_enable_fips() are not thread safe. They are
intended to be called only during the initialisation phase of a
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
libctx, otherwise it returns 0.
