I think the preceding part is more worrying: – the sequence of the operations is: first encryption and then signing, – the encryption algorithm AES (Advanced Encryption Standard) with 256 bit key length and RSA with 1024 bit key length shall be applied for symmetric and asymmetric encryption respectively, – the hash algorithm SHA-1 shall be applied. Really?
