I'm relatively new to cryptography and Crypto++, can someone comment on whether what I want to do sounds "correct" (whatever correct > means!)
- I want to encrypt data, that is to be transmitted around the inter/intraNet, using Rijndael
- I want to use a key for the above encryption that is an SHA128/256 hash based on: -
{multiple concatenated string data components} + {a nonce}
This provides some security, but it would be more useful if you were to explain what sort of data you're trying to protect and what kinds of attacks you're trying to prevent. Whether you're concerned about passive listening attacks vs attacks where packets can be intercepted and/or modified en route will dictate what type of encryption you should use, for example.
