STEP 01 // CRYPTO CORE

AES-256-GCM

The first line of defense. Data is encrypted using the AES-256 algorithm in GCM mode. This not only hides the content but also guarantees computational integrity: any attempt to modify even a single vault pixel is instantly detected by the system.

> Cipher: AES-256-bit
> Mode: Authenticated GCM
> Auth Tag: 128-bit MAC

STEP 02 // KEY DERIVATION

PBKDF2 Derivation

Access protection. Your PIN code is not used directly. Through the PBKDF2 algorithm with 100,000+ hashing iterations and a Salt, it is transformed into a complex 256-bit key. This makes any automated password brute-forcing useless.

> Hash: SHA-256
> Iterations: 100,000+
> Salt entropy: High-Density

STEP 03 // INVISIBILITY SYNTHESIS

LSB Injection

Final masking. The Least Significant Bit method replaces the lower bits in PNG pixels. The color change is less than 0.4%, making the presence of data mathematically indistinguishable from natural camera digital noise.

> Payload: ~12.5% VRAM
> Noise var: < 0.0039 per px
> Detection: Below human threshold

STEP 04 // ZERO-KNOWLEDGE

Zero-Knowledge

Ephemeral storage architecture. We do not log keys and do not save your files. Data exists only in the server's volatile memory (RAM) for the duration of the session. After download, the system permanently erases all traces.

> Storage type: Volatile RAM
> Session TTL: Ephemeral
> Persistence: Zero

SwissPhrase Protocol: Security Through Invisibility

We have combined cryptographic best practices with the art of steganography. Your information is not just protected — no one will even suspect its existence within the file.
