The Cryptsidian plugin provides a robust solution for encrypting all files in your Obsidian vault using a password, ensuring your data remains secure and private. Designed for desktop use, the plugin encrypts notes and attachments directly on disk with AES-256 encryption, protecting sensitive information from unauthorized access. Users can easily encrypt and decrypt their vault through modals accessed via the command palette. The plugin is particularly useful for shared device scenarios, such as family or public computers. It automatically closes open files during encryption to prevent corruption and emphasizes the importance of password retention, as files are irretrievable without it. While offering strong encryption, the plugin is not audited for critical security use cases.
