VidRelay

VidRelay — Local Video Encryption & Secure Distribution Do you have videos you don't want others to see? Or paid content you need to deliver safely to students or clients without worrying about leaks? VidRelay is a real encryption tool — not just "hiding." Every video is encrypted with AES-256-GCM chunk by chunk. The key is derived from your password and never stored in any file. Without the password, no one can play it. Why VidRelay? Real encryption, not hiding: AES-256-GCM per-file. Disk always holds ciphertext. Password not stored; required on every playback. Fully local, zero network: No server, no account. Data never leaves your device. No upload, no sync, no collection. Watermark protection: Watermark burned into video before encryption. Supports text (user ID/phone) and dynamic marquee for leak tracing. Expiration control: Set an expiry date. After that, playback is blocked. Ideal for courses, training, limited-time distribution. Export standalone EXE: Package encrypted video + player into a single Windows executable. Recipient double-clicks to play, no install needed. Universal player: Play .smvid files on Windows. Just enter the password. Who is it for? Personal privacy: Encrypt private videos. Play securely on iPhone or Windows. Content creators: Encrypt courses/tutorials. Control playback permissions and expiration. Corporate training: Encrypt internal materials. Distribute safely to employees. Free vs Pro Free version encrypts up to 3 videos, with full encryption, local playback, and basic watermark.
