NAME

       RSA_new, RSA_free - allocate and free RSA objects

SYNOPSIS

        #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);

DESCRIPTION

       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.

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.

SEE ALSO

       ERR_get_error(3), RSA_generate_key(3), RSA_new_method(3)

HISTORY

       All functions described here were deprecated in OpenSSL 3.0.  For replacement see EVP_PKEY-RSA(7).
