One of my favorites is the Speck cipher, which has been released before: https://en.wikipedia.org/wiki/Speck_(cipher) https://en.wikipedia.org/wiki/Speck_(cipher) I'd be very interested in more public cryptanalysis of this. It's a damn simple cipher to implement, and if it were at least as secure as say Salsa20/12 it'd be very nice for all kinds of applications.
