1=pod 2 3=head1 NAME 4 5RSA_new, RSA_free - allocate and free RSA objects 6 7=head1 SYNOPSIS 8 9 #include <openssl/rsa.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 RSA *RSA_new(void); 16 17 void RSA_free(RSA *rsa); 18 19=head1 DESCRIPTION 20 21RSA_new() allocates and initializes an B<RSA> structure. It is equivalent to 22calling RSA_new_method(NULL). 23 24RSA_free() frees the B<RSA> structure and its components. The key is 25erased before the memory is returned to the system. 26If B<rsa> is NULL nothing is done. 27 28=head1 RETURN VALUES 29 30If the allocation fails, RSA_new() returns B<NULL> and sets an error 31code that can be obtained by L<ERR_get_error(3)>. Otherwise it returns 32a pointer to the newly allocated structure. 33 34RSA_free() returns no value. 35 36=head1 SEE ALSO 37 38L<ERR_get_error(3)>, 39L<RSA_generate_key(3)>, 40L<RSA_new_method(3)> 41 42=head1 HISTORY 43 44All functions described here were deprecated in OpenSSL 3.0. 45For replacement see EVP_PKEY-RSA(7). 46 47=head1 COPYRIGHT 48 49Copyright 2000-2021 The OpenSSL Project Authors.
