With Hesekiel 1.2, the browser-based encryption tool receives several security-related and structural improvements. The focus is on local processing, clear key separation, and improved usability — without installation, without servers, and without data transmission.
Texts and files can be encrypted and decrypted entirely within the browser. All cryptographic operations are performed locally.

👉 Offline use as a single HTML file 💾 (Windows, Linux, macOS)
Overview 📋
Hesekiel is a lightweight tool for encrypting texts and files, executed directly in the browser.
Key derivation is based on:
- a password 🔑
- and a date as an additional factor 📅
Decryption is only possible with exactly matching values.
✔ no login
✔ no cloud
✔ no installation
✔ fully offline-capable
Use Cases 🧩
Secure text transmission ✉️
Encrypted content can be sent via email or other communication channels. The password and date are shared separately from the encrypted content.
Protected notes 🗒️
Internal information, personal data, or project-related content can be stored securely in encrypted form.
File encryption (.enc) 📁
Any file can be converted into an encrypted format and restored only with the correct password and date.
Offline Use Without Data Exposure 💾🔒
A key feature of Hesekiel is its full offline capability.
The tool can be saved as a single HTML file and executed locally in a browser — without any network connection.
Characteristics of offline usage
- no internet connection required
- no server communication
- no logging
- no data transfer
- no administrative access to content
Encryption and decryption take place exclusively within the local browser environment. Content never leaves the system.
Even within internal networks or during email transmission, no one can read the content, as only encrypted data is present.
