1=pod 2 3=head1 NAME 4 5EVP_set_default_properties, EVP_default_properties_enable_fips, 6EVP_default_properties_is_fips_enabled 7- Set default properties for future algorithm fetches 8 9=head1 SYNOPSIS 10 11 #include <openssl/evp.h> 12 13 int EVP_set_default_properties(OSSL_LIB_CTX *libctx, const char *propq); 14 int EVP_default_properties_enable_fips(OSSL_LIB_CTX *libctx, int enable); 15 int EVP_default_properties_is_fips_enabled(OSSL_LIB_CTX *libctx); 16 17=head1 DESCRIPTION 18 19EVP_set_default_properties() sets the default properties for all 20future EVP algorithm fetches, implicit as well as explicit. See 21L<crypto(7)/ALGORITHM FETCHING> for information about implicit and explicit 22fetching. 23 24EVP_set_default_properties stores the properties given with the string 25I<propq> among the EVP data that's been stored in the library context 26given with I<libctx> (NULL signifies the default library context). 27 28Any previous default property for the specified library context will 29be dropped. 30 31EVP_default_properties_enable_fips() sets the 'fips=yes' to be a default property 32if I<enable> is non zero, otherwise it clears 'fips' from the default property 33query for the given I<libctx>. It merges the fips default property query with any 34existing query strings that have been set via EVP_set_default_properties(). 35 36EVP_default_properties_is_fips_enabled() indicates if 'fips=yes' is a default 37property for the given I<libctx>. 38 39=head1 RETURN VALUES 40 41EVP_set_default_properties() and EVP_default_properties_enable_fips() return 1 42on success, or 0 on failure. An error is placed on the error stack if a 43failure occurs. 44 45EVP_default_properties_is_fips_enabled() returns 1 if the 'fips=yes' default 46property is set for the given I<libctx>, otherwise it returns 0. 47 48=head1 SEE ALSO 49 50L<EVP_MD_fetch(3)> 51 52=head1 HISTORY 53 54The functions described here were added in OpenSSL 3.0. 55 56=head1 COPYRIGHT 57 58Copyright 2019-2021 The OpenSSL Project Authors.
