My field is Software Development with focus on Information Security.
I’m specialized in security protocols like S/MIME, SSL/TLS. I have implemented the protocols from scratch using Delphi programming language, to be used in commercial software for more than 20 years. As about underlying cryptography algorithms, I prefer open source implementation written in C or Assembler.
