Vector Steganography (SVG)

Hides encrypted text in the XML structure of an SVG file via a container, without changing the visual appearance of the vector.

-container — Argon2id + AES-CTR + HMAC-SHA256. The cipher is embedded in the tag <metadata id="sanmavsans-core-crypto">. Dual layer and burn-password are supported.

How to use:

Upload the source SVG file (XML vectors only, not a PNG wrapped in SVG).
Enter the secret message and the main password.
Dual layer: open advanced options and specify a decoy text + a decoy password.
Download the secured SVG — visually it is identical to the original.
For extraction: upload the secured SVG and enter the same password.
