The guardian of the dead, ever present.
The sentinel of the graveyard, always watching.
Decade upon decade, watching over those who have gone before.
Beard ever growing, body moving slowly.
The old man of the graveyard.
Director of Security at 1Password, researcher and software developer with more than 20 years of experience.
I primarily focus on application security, secure communications, and cryptography, though often research new areas if I get too bored. I write about my research and security in general, development and software design, and whatever hobby has my attention at the moment.
