• •Creator released 'sod', a tool that generates non-exportable ecdsa-sha2-nistp256 keys directly within the Apple Secure Enclave.
• •The tool functions by orchestrating a minimal ssh-agent, allowing standard OpenSSH server authentication via Touch ID/Biometrics.
• •Hardware-level key isolation provides significant security, though the project is in early stages and lacks long-term testing or cross-platform support.

The developer-led project 'sod' allows users to store SSH keys inside the Apple Secure Enclave for biometric-backed authentication. While native hardware keys like YubiKeys have long set the standard for physical security, this approach utilizes existing Mac hardware to achieve similar isolation without external peripherals. However, because this is an early-stage tool, its robustness in enterprise environments or high-concurrency workflows remains unverified. Its success will likely depend on whether users prioritize local hardware integration over more established, vendor-neutral hardware security modules.
