Security and privacy utilities for common browser workflows
Kaazo Security Utilities combines local generators and document privacy tools. Create random passwords and UUID v4 identifiers, calculate SHA-256 hashes, sign PDF documents, permanently redact page areas, fill and flatten PDF forms, or remove PDF metadata from a dedicated tool page.
Security tools need careful use. A generated password should be stored in a reputable password manager, a hash is not encryption, and redacted or signed documents should be opened and visually checked before they are distributed. Kaazo keeps these workflows simple while leaving final verification with the user.

Why Kaazo uses task-specific tool pages
