Hi.
This is the first time I'm working to encrypt some data. So, any
advise or pointer to sites or books are deeply appreciated.
I need to encrypt ( and of course decrypt) data that is not larger
than 500KB in real time (i.e. less than one fifth or 0.2 of a sec).
Since the data is easily accessible by unauthorized users, I would
also need the method to easily render the entire data useless once a
single byte of information is altered. Are there existing algorithm or
some combination of methods that could achieve that? Or should I read
up more books and cook up my algorithm?
Thanks in advance.
