Hybrid Envelope Encryption: RSA-4096-OAEP + AES-256-GCM

AlphaTech combines 4096-bit asymmetric RSA key wrapping with authenticated symmetric AES-256-GCM ciphertexts so large KYC, SAT CFDI, or judicial payloads remain confidential and tamper-evident with sub-millisecond cryptographic overhead.

• Ephemeral Content Key: A fresh 256-bit AES key and nonce are generated in volatile memory for every individual transaction.
• Authenticated Encryption: Payloads are encrypted with AES-256-GCM, guaranteeing both confidentiality and integrity via authentication tags.
• Key Wrapping & Anti-Replay: The ephemeral AES key is wrapped using your registered RSA-4096-OAEP-SHA256 public key, while requests validate X-TIMESTAMP windows and RSA-PSS signatures.
• Official SDK Helpers: Built into our official Python (alphatech-sdk) and Node.js (@alphatechsis/sdk) packages for rapid integration.
