Technical Expertise: Strong understanding of cryptographic primitives and protocols — symmetric and asymmetric encryption, hashing, digital signatures, TLS/PKI. Deep, hands-on knowledge of key management (generation, rotation, escrow, destruction, KMS/HSM integration) and fluency in industry-wide standards and frameworks, including NIST SP 800-57, FIPS 140-2/140-3, and NIST’s post-quantum cryptography standards.
