Well, this is a combined method. This is an asymmetric method, which means that one pair of RANDOM keys are created. The files are then encrypted using the public key and can only be decrypte by the private key.
The key itself is encrypted using theb RSA method (1024 bits), so this is pretty secure. The random 256 bit key is then used to encrypt the files with Rijndael. A 256 key is not so strong nowdays, but due to the key being random AND encrypted with 1024 bits makes the method more secure that using plain Rijndael.
