=pod =head1 NAME RSA_new, RSA_free - allocate and free RSA objects =head1 SYNOPSIS #include <openssl/rsa.h> RSA * RSA_new(void); void RSA_free(RSA *rsa); =head1 DESCRIPTION RSA_new() allocates and initializes an B<RSA> structure. It is equivalent to calling RSA_new_method(NULL). RSA_free() frees the B<RSA> structure and its components. The key is erased before the memory is returned to the system. =head1 RETURN VALUES If the allocation fails, RSA_new() returns B<NULL> and sets an error code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer to the newly allocated structure. RSA_free() returns no value. =head1 SEE ALSO L<ERR_get_error(3)|ERR_get_error(3)>, L<rsa(3)|rsa(3)>, L<RSA_generate_key(3)|RSA_generate_key(3)>, L<RSA_new_method(3)|RSA_new_method(3)> =head1 HISTORY RSA_new() and RSA_free() are available in all versions of SSLeay and OpenSSL. =cut
