Summary
👤
Senior🎓
Top SchoolHannu Honkanen is a Specialist in Software Development and Security based in Helsinki with over a decade of hands-on experience designing software architectures and implementing everything from low-level drivers to user interfaces. He combines practical cryptographic key management and PKI expertise with smart card development and information security consulting, grounded in early career experience producing and personalizing smart cards. At Aventra he steers security-focused engineering and documentation, and as an active OpenSC contributor has deepened ECC support for MyEID cards—adding 521-bit ECC handling and implementing secure key wrap/unwrap operations. That blend of operational production knowledge and protocol-level cryptography gives him a rare end-to-end perspective on secure identity systems. He holds a BBA in Information Technology from Haaga-Helia and favors solving subtle protocol and interoperability issues that others often overlook.
