Length of message in RSA and splitting of long messages

Web1 jun. 2015 · If the payload doesn't exceed 300 bytes and you're using OAEP (at least 42 bytes of padding), then you can easily calculate the minimum key size: (300 + 42) * 8 = 2736 bit That's already a reasonable size key. It provides good security according to today's norms and is fairly fast. There is no need to apply a hybrid encryption scheme for this.

Web31 mrt. 2016 · So the output of a 2048 bit RSA calculation is just 2048 / 8 = 256 bytes. So in principle you can encrypt blocks of 214 bytes and output 256 bytes with a 2048 bit key. This is very inefficient, especially during decryption with the private key. Furthermore, you'd have the 42 bytes of overhead to deal with.
