RSA_new, RSA_free - allocate and free RSA objects
#include <openssl/rsa.h>
The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining
OPENSSL_API_COMPAT with a suitable version
value, see
openssl_user_macros(7):
RSA *RSA_new(void);
void RSA_free(RSA *rsa);
RSA_new() allocates and initializes an
RSA structure. It is
equivalent to calling RSA_new_method(NULL).
RSA_free() frees the
RSA structure and its components. The key is
erased before the memory is returned to the system. If
rsa is NULL
nothing is done.
If the allocation fails,
RSA_new() returns
NULL and sets an error
code that can be obtained by
ERR_get_error(3). Otherwise it returns a
pointer to the newly allocated structure.
RSA_free() returns no value.
ERR_get_error(3),
RSA_generate_key(3),
RSA_new_method(3)
All functions described here were deprecated in OpenSSL 3.0. For replacement see
EVP_PKEY-RSA(7).
