1=pod 2 3=head1 NAME 4 5DSA_new, DSA_free - allocate and free DSA objects 6 7=head1 SYNOPSIS 8 9 #include <openssl/dsa.h> 10 11The following functions have been deprecated since OpenSSL 3.0, and can be 12hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, 13see L<openssl_user_macros(7)>: 14 15 DSA* DSA_new(void); 16 17 void DSA_free(DSA *dsa); 18 19=head1 DESCRIPTION 20 21All of the functions described on this page are deprecated. 22Applications should instead use L<EVP_PKEY_new(3)> and L<EVP_PKEY_free(3)>. 23 24DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to 25calling DSA_new_method(NULL). 26 27DSA_free() frees the B<DSA> structure and its components. The values are 28erased before the memory is returned to the system. 29If B<dsa> is NULL nothing is done. 30 31=head1 RETURN VALUES 32 33If the allocation fails, DSA_new() returns B<NULL> and sets an error 34code that can be obtained by 35L<ERR_get_error(3)>. Otherwise it returns a pointer 36to the newly allocated structure. 37 38DSA_free() returns no value. 39 40=head1 SEE ALSO 41 42L<EVP_PKEY_new(3)>, L<EVP_PKEY_free(3)>, 43L<DSA_new(3)>, L<ERR_get_error(3)>, 44L<DSA_generate_parameters(3)>, 45L<DSA_generate_key(3)> 46 47=head1 HISTORY 48 49All of these functions were deprecated in OpenSSL 3.0. 50 51=head1 COPYRIGHT 52 53Copyright 2000-2021 The OpenSSL Project Authors.
