WebFeb 28, 2016 · 1. RSA encryption is limited to encrypting data shorter than it's key size. A 1024-bit key can encrypt up to 127-bytes and 2048-bit key can encrypt up to 255-bytes with textbook RSA. For larger data encrypt the data with AES and a random key and then encrypt the key with RSA. – zaph. WebA. The Websense redirect Web filter solution does not require a license on the SRX device. B.
