Security Principles:

• Misuse-Resistant APIs High-level cryptographic interfaces reduce developer error and unsafe composition.

• Constant-Time Operations Cryptographic implementations are designed to mitigate timing-based side-channel attacks.

• Hardware-Backed Key Protection Private keys are protected using OS-native secure storage and hardware-backed enclaves where supported, including Secure Enclave, Android Keystore, and TEE-backed services.
