Signal is the best private messaging system available to a non-technical consumer. But it’s not designed for classified communications. And you can get better security and privacy but there are real trade offs. This is all ok.

For the record:

- The *cryptography* in Signal is probably fine; a practical attack would be a big surprise.

- Signal lacks specific features required for classified systems, such as security labels, certified identities, revocation, etc.

- Signal runs on uncontrolled, insecure platforms connected to the Internet, rendering it unsuitable for classified even if it had the above features.

- Adding classified features to Signal would make it unusable for most purposes for which it's intended.
