This comprehensive guide outlines security best practices for utilizing Vast.ai's cloud environment. It covers secure API key management, hardening SSH access to GPU instances, implementing proper data cleanup before instance destruction, and adhering to robust network security protocols. Use this when setting up, auditing, or deploying sensitive AI/ML workloads on shared cloud hardware.

This skill provides a comprehensive guide to configuring Hardware Security Modules (HSMs) using the industry-standard PKCS#11 interface. It details best practices for key generation, secure key storage, and cryptographic operations (signing, encryption, decryption). Learn how to manage keys in a tamper-resistant environment, ensuring private keys never leave the device boundary. Applicable for building compliance-grade security architectures across finance and government sectors.

This skill demonstrates how to integrate Hardware Security Modules (HSMs) using the standard PKCS#11 interface. It covers secure key generation, signing, encryption, and verification operations directly on the hardware. Ideal for security assessments, compliance audits (FIPS 140-2/3), and validating cryptographic controls using tools like python-pkcs11, AWS CloudHSM, and YubiHSM2.

A comprehensive guide for implementing phishing-resistant multi-factor authentication using FIDO2/WebAuthn protocols. Learn to build a complete relying party server using Python, supporting both roaming hardware keys (e.g., YubiKey) and platform biometrics. Covers registration ceremonies, credential storage, and migrating to passwordless authentication.
