It's funny how mere icons can make me happy. I saw these icons today as successful result of my recent crypto works. They say Acrobat, Signable, Certified, Encrypted, Certification Signature, and Verified Signature.
For my client, above set of symbols means an encrypted, certified, and signed PDF document. For me, it means I am happy. As I learned over the years, regular doses of small happyness is what life is all about.
