[Release 0.2.0] VSCode-compatible extension for browsing crypto files/vaults

Marcus-Aprelius — Wed, 16 Sep 2026 13:33:04 +0000

I have released a new version of SATO, a VS Code-compatible extension for viewing and managing cryptographic files and password vaults.
This release introduces a significantly improved interface, enhanced crypto file inspection, and a built-in converter for X.509 certificates and OpenSSH public keys.

It also includes extensive testing, code refactoring, stability improvements, and many smaller changes that together provide a much better experience and expand SATO’s capabilities.

P.S.: The project is under development; so please use in production with caution!

VSCode-compatible extension for browsing crypto files/vaults

Marcus-Aprelius — Tue, 08 Sep 2026 12:15:59 +0000

Tired of using different command-line tools for different crypto files and password databases, I built a VS Code extension to keep everything inside the editor.

Current approach:

Approach with VSCode extension:

Current features:

Browse:
- password vaults (.kdbx, .psafe3, .ibak, .1pif, .bcup)
- secure containers and keystores (.p12, .pfx, .jks, .jceks)
Inspect:
- certificates, keys and signatures (.crt, .cer, .der, .pem, .key, .csr, .p10, .p7b, .p7c, .p7s, .p7m)
- SSH, PuTTY, OpenPGP, and AGE files (.ppk, id_rsa, id_ecdsa, id_ed25519, .gpg, .pgp, .asc, .sig, .age)
Detect certificate duplicates
Generate secure passwords
View certificate chains and metadata

Project goals:

Replace multiple command-line tools with a single UI (in progress)
Support additional cryptographic formats, wallets, and containers (planned)
Add functionality such as conversion, export, and other utilities (planned)

Many thanks in advance for your overview and constructive feedback.

P.S.:
Please use test files and non-production data when evaluating the extension, as bugs and unexpected behavior may still occur.
