CipherVault provides free, browser-based encryption, encoding, and cryptography tools. Our mission is to make cryptographic tools accessible to everyone — from security professionals to casual users who simply need to encode a URL or generate a password.
Every tool on CipherVault runs entirely in your web browser. No data is transmitted to our servers. No inputs are logged or stored. Your text, passwords, and files never leave your device. This is not just a policy — it is a technical guarantee. Our tools use only client-side JavaScript with no server-side components.
All tools are free to use with no limits, no accounts required, and no premium tiers. We sustain the site through minimal, non-intrusive advertising.
Our encoding and hashing tools produce results that match standard implementations. Base64 output is identical to what any standard library would produce. SHA-256 hashes use the Web Crypto API, which is the same implementation your browser uses for TLS connections. Caesar cipher output is mathematically correct.
While our tools are accurate and educational, they are not intended as production security solutions. For actual security implementations, use well-tested libraries (OpenSSL, libsodium, Web Crypto API) and consult security professionals. Our tools are excellent for learning, testing, and quick tasks.
