"Dotenvx: Reducing Secrets Risk with Cryptographic Separation

Abstract. An ideal secrets solution would not only centralize secrets but also contain the fallout of a breach. While secrets managers offer centralized storage and distribution, their design creates a large blast radius, risking exposure of thousands or even millions of secrets. We propose a solution that reduces the blast radius by splitting secrets management into two distinct components: an encrypted secrets file and a separate decryption key.

Dotenvx decrypts your .env files. Using with cryptographic separation limiting their attack vector while retaining their benefits. Allowing use in small projects, on virtual servers, where it is not possible to run an external startup script for the application.

Important

But for this to be effective, the decryption keys (private key) and the application must be in separate environments, while maintaining security in each environment.
