Sec2M

Local, serverless CLI secrets manager using a compact custom file format.

Desktopfreeglobal

Sec2M is a free, open-source Go CLI secrets manager with no runtime dependencies, storing entries in its own compact binary format rather than KDBX/XML. It offers strong encryption (XChaCha20, Argon2id), whole-file integrity checking, an internal Unix-style shell for navigating entries, and a documented hardening guide against local malware. It suits developers and power users who want a minimal, dependency-free local secrets store.
