Why is it important never to reuse a nonce?
·
A nonce is an important element in cryptography and keep your data secure. But if you ever reuse a nonce, you’ve lost any hope for secrecy.

End-to-end encrypted secret sharing
·
Secret sharing typically requires a trusted third party to communicate a secret from point A to B. Encrypting those secrets at point A and only allowing point B to decrypt them removes any risk in the transfer.

Ethical Quandary: iPhones and Encryption
·
Is Apple’s new stance on phone data encryption a good thing or a bad thing? The FBI, at least, thinks it’s bad. I say they’re wrong.
