To encrypt a file with a password, you can prompt the AI with natural language like “Encrypt secrets.txt with a password to secrets.safe.” The system then executes the appropriate SAFE cryptography command or browser action to secure your data.

Multi-recipient encryption is supported, allowing you to secure a single file for multiple users simultaneously. You can specify recipients by name, such as prompting the AI to encrypt a document for both alice and bob using composable paths.

Local compiler installation is not strictly required. While you can install the SAFE CLI locally for command-line encryption, the tool also supports browser-based workflows as a fallback for environments lacking compilers.

For agent-to-agent messaging, the best approach is using the built-in key management features to generate keypairs and manage recipients. This enables secure message exchange and can automatically generate project documentation like AGENTS.md.

Besides password-based encryption, you can use public-key encryption and multi-factor security. The tool supports composable recipient paths, allowing you to combine key-based and password-based methods for layered file protection.

Post-quantum encryption should be used when securing sensitive file workflows, managing secrets, or facilitating agent-to-agent messaging against future quantum threats. It reduces data exposure risks in insecure environments using SAFE cryptography.
