Function Documentation

  void RSA_free (RSA * rsa)

Free an allocation RSA object.

Parameters:
    rsa the RSA object to free.

  void* RSA_get_app_data (RSA * rsa)

Get the application data for the RSA object.

Parameters:
    rsa the rsa object to get the parameter for

Returns:
    the data object

  const RSA_METHOD* RSA_get_method (const RSA * rsa)

Return the RSA_METHOD used for this RSA object.

Parameters:
    rsa the object to get the method from.

Returns:
    the method used for this RSA object.

  RSA* RSA_new (void)

Same as RSA_new_method() using NULL as engine.

Returns:
    a newly allocated RSA object. Free with RSA_free().

  RSA* RSA_new_method (ENGINE * engine)

Allocate a new RSA object using the engine, if NULL is specified as the engine, use the default RSA engine as returned by ENGINE_get_default_RSA().

Parameters:
    engine Specific what ENGINE RSA provider should be used.

Returns:
    a newly allocated RSA object. Free with RSA_free().

  int RSA_set_app_data (RSA * rsa, void * arg)

Set the application data for the RSA object.

Parameters:
    rsa the rsa object to set the parameter for
    arg the data object to store

Returns:
    1 on success.

  int RSA_set_method (RSA * rsa, const RSA_METHOD * method)

Set a new method for the RSA keypair.

Parameters:
    rsa rsa parameter.
    method the new method for the RSA parameter.

Returns:
    1 on success.

  int RSA_up_ref (RSA * rsa)

Add an extra reference to the RSA object. The object should be free with RSA_free() to drop the reference.

Parameters:
    rsa the object to add reference counting too.

Returns:
    the current reference count, can't safely be used except for debug printing.
