We do not have a server. We do not have a database. If you encrypt a message and forget the passphrase, that data is cryptographically shattered and permanently unrecoverable by anyone, including us.
Cryptographic Architecture
What is AES-256-GCM?
Advanced Encryption Standard (AES) with a 256-bit key size is the global standard for military-grade encryption. GCM (Galois/Counter Mode) provides authenticated encryption, meaning it guarantees both the confidentiality and the integrity (tamper-proofing) of your data.
How is my password processed?
Passwords aren't secure enough to be raw AES keys. We use PBKDF2 (Password-Based Key Derivation Function 2) executed 100,000 times against a randomized cryptographical salt to derive a mathematically secure 256-bit key from your text password.
What is a "Unified Payload"?
To decrypt data, you need the original Salt and Initialization Vector (IV). Our protocol automatically concatenates them: Base64(Salt + IV + Ciphertext). This ensures you only have to copy a single string.
