RSA_new(3)                   OpenSSL                   RSA_new(3)

NAME

     RSA_new, RSA_free - allocate and free RSA objects

SYNOPSIS

      #include <openssl/rsa.h>

      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.

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.

HISTORY

     RSA_new() and RSA_free() are available in all versions of
     SSLeay and OpenSSL.
