CipherVault is an innovative, professional, secure, and fully local tool for encrypting and decrypting photos, videos, and files, allowing you to truly control your privacy. It adopts a local file encryption scheme of PBKDF2-HMAC-SHA256+AES-256-GCM, and encapsulates the ciphertext into a custom. tycv encryption container format. Provide high-strength protection for private photos, private videos, and various important files. Unlike ordinary encrypted photo albums that only hide the entrance, CipherVault will truly encrypt the original file into ciphertext, and without the correct key, it cannot be decrypted. The encrypted files can be freely stored on mobile phones, computers, the cloud, or securely shared and transmitted. You can also set multiple different keys to encrypt different files separately. All encrypted files cannot be opened or viewed directly and must be restored through CipherVault with the correct key. Core Advantages: **Independent keys, flexible management Support custom, user‑defined keys, create multiple keys and set a default key at any time – different files can be encrypted with different keys. **Cross‑device freedom, seamless transfer The unique encryption format allows encrypted files to be securely transferred and decrypted across different devices. You can back up the ciphertext to your phone, computer, or cloud, then import it to any device when needed and decrypt it with your key. **Full format support, one‑tap encryption Whether it’s an image, video, or any other file, encryption can be done with one tap – no format restrictions. **Batch processing, high efficiency Encrypt or decrypt multiple files at the same time, greatly improving efficiency and saving time and effort. **Local, fast, and secure All encryption and decryption operations are performed locally on your device, with no data upload – ensuring both security and speed. Core Features: • Photo encryption: Batch‑encrypt photos into ciphertext to prevent unauthorised viewing. • Video encryption: Batch‑encrypt videos into ciphertext to protect private footage. • File encryption: Batch‑encrypt any files into ciphertext, covering documents, archives, and all other formats. • Decryption & restore: Verify the security key and restore the original content with one tap. • Double security lock: Enable “password + Face ID” double unlock in settings, adding an extra layer of security to your privacy. • Key management: Centrally manage multiple keys, assign different keys to different files for fine‑grained access control. **********Use Cases********** 1. Protect personal privacy Don’t want others to browse the private photos or videos on your phone or computer? Use CipherVault to encrypt them – only you can decrypt and view them, completely eliminating the risk of privacy leaks. 2. Safeguard important documents Confidential files such as contracts, ID documents, and financial records need strict protection. With CipherVault’s strong encryption, even if your device is lost or accessed by someone else, the file contents remain unreadable. 3. Secure transmission and sharing When sending sensitive files over the internet, encrypt them first with CipherVault, then send the ciphertext to the recipient. The recipient only needs the key you provide to decrypt and view them, preventing leaks during transmission. 4. Lock down cloud backups Upload encrypted files to cloud storage – even if the cloud provider is breached or your account is stolen, the other party sees only unreadable ciphertext, ensuring your cloud data is truly secure.
