Architectural Overview & Selection Guide
Curated AnalysisZero-Knowledge Encryption & Ephemeral Security Primitives
Privacy tools should never demand personal identifiers to protect personal data. The privacy utilities curated here represent the gold standard of zero-knowledge architecture: they operate entirely without user registration, collect no device telemetry, and utilize mathematical encryption standards to guarantee security.
Architecture & Privacy Logic
These utilities make extensive use of the Web Cryptography API (SubtleCrypto) to execute AES-GCM-256 and RSA encryption on the client. Keys are derived locally using PBKDF2/Argon2. In file encryption tools like Hat.sh, the browser never transmits files or decryption keys to a server, ensuring mathematical confidentiality.
+ What You Gain
Cryptographic guarantee of privacy, immunity to server subpoena or cloud data breaches, and zero account trail.
− What You Sacrifice
Lost passwords or encryption keys cannot be recovered by customer support due to true zero-knowledge design.
Encrypt sensitive attachments with Hat.sh before sending, verify breach exposure with Have I Been Pwned via k-anonymity, and audit your browser posture using PrivacyTests.
