Syntecian Vault

Testing retention: While testing, files are saved for 24 hours, then deleted. After site testing is finished, files will be deleted after processing.
Encrypted image container

Hide encrypted files inside an image

Select a carrier image, add the files you want to protect, and Syntecian will encrypt them with AES-256-GCM before packaging them inside the image. The visible image remains viewable.

Important: Keep the generated encryption key somewhere safe. Syntecian does not place the key inside the image. Resaving, optimizing, or recompressing the encoded image may remove the hidden package.

AES
AES-256-GCM authenticated encryption

A random 256-bit key is generated for every package. Authentication detects an incorrect key or altered payload.

Encrypted first

Your selected files are packaged together and encrypted before they are embedded in the carrier image.

Separate key

The decryption key is displayed separately. Anyone with only the encoded image cannot decrypt the contents without that key.

24-hour testing cleanup

During testing, server-side processing files are retained for up to 24 hours and then automatically deleted.
