I dislike using stream ciphers in general because they
don't achieve diffusion; that complicates key management
and introduces possibilities for making encryption
mistakes. So I evaluate Spritz as a Random Number
generator rather than a cipher, and find it ... okay.
There are faster ones on desktop hardware of course,
but they're easy to get wrong if you're coding. I
like Spritz' simplicity, because that makes for robust
If you do the fiddly key management and IV things
correctly to use it for a stream cipher, you can do
that. But I treat it as a simple, robust CSPRNG.
I would be okay if confident that it's well initialized,
using it to generate a key for a solid block cipher.
