I grew up on the internet using Pretty Good Privacy (PGP), an email encryption software package. It was the first encryption software that I used, and for a long time the only encryption that I used. Being like most on the internet, I did not encrypt my personal emails. It was cumbersome, the people receiving my email were not using encryption, and I felt I had nothing to hide in my email communications. I primarily used PGP to encrypt account credentials and credit card information on the server for the systems that I developed.
Phil Zimmermann is the creator of PGP. After the 2010 sale to Symantec, PGP was no longer an option for our software development requirements and I started using other solutions for server side encryption. Even the creator of PGP no longer uses PGP.
Now I am thinking about email encryption again. Phil Zimmerman's new company, Silent Circle, looks very interesting, but is focused on enterprise solutions where everyone involved prioritizes private communication.
