RSA_new, RSA_free — allocate and free RSA objects


#include <openssl/rsa.h>
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.

Return Values

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.
