Military-grade encryption hidden within ordinary images. Your data is encrypted, concealed, and blockchain-verified.
Files are encrypted with a randomly generated AES key, then the key itself is wrapped with RSA-2048 public key cryptography.
Encrypted data is embedded into carrier images using least-significant-bit encoding with seeded PRNG pixel ordering.
SHA-256 hashes are recorded on-chain for tamper-proof verification. Any modification to the data is instantly detectable.
Select your secret file and a carrier image. The system validates file types, sizes, and image capacity.
Your file is encrypted with AES-256-GCM. The symmetric key is wrapped with RSA-2048 for secure storage.
Encrypted data is hidden inside the carrier image using 2-bit LSB steganography with randomized pixel ordering.
A SHA-256 integrity hash is computed and stored on the blockchain for tamper detection.
You receive a stego image that looks identical to the original but contains your encrypted data.
