LSB: modifies pixel values — visually undetectable
how it works
LSBEach pixel's least significant bit is flipped to store your data. One bit per channel means ~3 bits per pixel — invisible to the human eye, undetectable without this tool.
AppendYour encrypted payload is appended after the image's byte stream. The image renders normally in any viewer; the data sits in the tail.
AES-256-GCMYour message is encrypted with AES-256-GCM before embedding. The password is never stored or transmitted. PBKDF2 with 200,000 iterations derives the key.
