问题描述:

RSA is public-key cryptosystems 2048 key size but its for block system cipher using AES 256 block size, but to using Stream system cipher Like RC4 256 bit, Isn't bit strange what about first 256 bit of cipher stream?

网友答案:

Hyper-cipher (Stream Ciphers and Block Ciphers): it's Cipher Combine a stream cipher algorithms with block cipher algorithms, to create a Strong Cipher which is using in both Block cryptography and Stream cryptography. for more info Stream Ciphers and Block Ciphers - Hyperelliptic org.
