Marcus-Aprelius — Thu, 24 Sep 2026 08:36:02 +0000

I have released a new version of SATO, a VS Code extension for browsing password vaults and inspecting cryptographic files.
This release expands format support, improves key and certificate detection, and makes the Crypto Converter more flexible.

More details about this release:
Crypto Support and Logic:

Improved PEM and DER key detection
Extended DER support for certificates, CSRs, RSA and EC keys, PKCS#7 chains, and CMS messages
Added support for new files (.rsa, .ec, and .spc) and Improved key detection and navigation for the existing
Added RSA and EC private key conversion to multiple PEM and DER formats
Added extraction of certificates and certificate chains from SPC containers Converter:
Converter splitted into separate Convert and Extract tabs
Added Extract... and Show Info context-menu actions
Removed the source format from available conversion targets
Improved output format handling and prevented stale output filenames
Added copy buttons to the source fields Interface:
Improved converter layout, alignment, and terminology
Added consistent tab styling across the main views
Added copy buttons to File Info values
Added tooltips for key size, file size, and certificate validity
Improved long field labels and empty-value handling
Added Show/Hide Empty Values support Code and Maintenance:
Refactored crypto conversion and extraction availability checks
Improved handling of empty and absent parsed values
Updated project dependencies and documentation And many other improvements.

SATO is still under development.

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

I have released a new version of SATO, a VS Code 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.

VSCode 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.
