01 // THE PROCESS

From Secret to Silence

Four phases of digital concealment. From plaintext to invisible. ECHO handles everything.

01
COMPOSE
Write your secret message. Choose your carrier image. Select encryption strength and encoding method.
02
ENCRYPT
Military-grade AES-256 encryption. Password-protected payloads. Zero-knowledge architecture.
03
EMBED
LSB steganography encodes data into pixel values. Visually identical output. Undetectable to the eye.
04
VERIFY
Statistical analysis confirms concealment. Chi-squared tests. Entropy checks. Your secret is safe.
02 // FEATURES

The Steganographer's Toolkit

Every tool needed to hide, detect, and decrypt hidden messages. Engineered for secrecy.

LSB STEGANOGRAPHY
Embed messages into the least significant bits of image pixels. Visually lossless. Statistically invisible.
AES-256 ENCRYPTION
Military-grade cipher before embedding. Even if detected, the message remains unreadable without the key.
STEGANALYSIS DETECTION
Scan any image for hidden payloads. Chi-squared analysis, entropy mapping, histogram comparison.
MULTI-FORMAT SUPPORT
PNG, BMP, TIFF carriers. Embed text, files, or binary data. Automatic capacity calculation.
GAMIFIED ACADEMY
Learn steganography through challenges. Progressive difficulty. Earn ranks from Initiate to Phantom.
VISUAL DIFF ENGINE
Compare original and stego images side-by-side. Amplified difference visualization. Bit-plane analysis.
BATCH PROCESSING
Embed or extract from multiple images at once. Configurable pipelines. Automated workflows.
DAEDALUS INTEGRATION
Part of the DAEDALUS suite. Seamless integration with HYDRA, TYPHOON, and the rest of the ecosystem.
