Building ProcPass, a local-first encrypted password manager (Go + React). The backend worked, but the frontend file was literally cut in half — missing screens, broken function calls, no CSS.

Today I fixed it:

• Built the full UI: create vault, unlock vault, add/edit/delete passwords
• Fixed a bug where the app sent the password twice instead of the vault file path (i was sleepy LoL) 💀
• Added a native file picker to choose where your vault is saved
• Dark theme, because obviously

Build passes clean.

ProcPass, My Own Password Manager

Today I implemented the core security model using envelope encryption. The master password never touches vault data. Instead, it derives a Key Encryption Key (KEK) that wraps the Vault Encryption Key (VEK, the actual key protecting your data).

The payoff is that changing master password is instant. Since the VEK stays the same, you only re-wrap 32 bytes with a new KEK. No re-encryption of the entire vault, even with thousands of entries.

I also started using AI for making better diagrams for the devlogs (they are way more beautiful than my handmade thinking LoL).
Special thanks for @lacorte that gived that idea for me ;)

Today I’m working on a Password Manager Desktop App, there is my thinking, any suggestions?
