How to Get Value From This Site
Start with a guide if you are deciding between algorithms or trying to understand how a workflow should be designed. Move into the tools once you know the outcome you want: confidentiality, integrity, token inspection, encoding, or key generation.
The goal is to reduce guesswork. A strong site in this space should not only provide utilities. It should explain when to use them, what assumptions they rely on, and how users can avoid obvious security mistakes.

Read Guide →Frequently Asked Questions
What is client-side encryption?
Client-side encryption means all cryptographic operations happen in your browser using JavaScript and the Web Crypto API. Your data never leaves your device, ensuring complete privacy. Unlike traditional web tools that upload your data to servers, our tools process everything locally.
Which encryption should I use?
For encrypting files or large amounts of data, use AES-256 symmetric encryption. For secure key exchange and digital signatures, use RSA or ECC asymmetric encryption. Most real-world systems use both (hybrid encryption) - RSA for key exchange, then AES for data encryption.
Are these tools really free?
Yes, all our encryption tools are completely free with no hidden costs, subscriptions, or premium tiers. We believe strong encryption should be accessible to everyone. The site is supported by non-intrusive advertisements that help us maintain and improve the service.
Is this secure for sensitive data?
Yes. We use industry-standard algorithms (AES-256, RSA-4096) and the browser's native Web Crypto API. Since all encryption happens locally in your browser and data never reaches our servers, it's as secure as using offline encryption software. However, always use strong, unique passwords and keep your encryption keys safe.
