Sign and crypt with one keypair

[ETeissonniere]

Hi, if I look at the Sealedbox example, you are using bliss keys. I would like to know if it is possible (and safe) to use one keypair (either newhope or bliss) to crypt, decrypt and sign data.

It is not possible because they are different algorithms.

OK, thanks
