PGP

This part of kzinhome.net is for storage of information regarding PGP/GPG.

PGP or Pretty Good Privacy is a piece of software that provides cryptographic privacy and authentication. There a lot to cover, just in that first sentence. I’ll let Wikipedia do it.

In order to engage in secure or authenticated communication with me, you should use PGP or GPG.

My public key can be found on all of the OpenPGP keyservers of which I am aware, but you can also download it here.

  • KeyID: F277FFD0
  • Key Fingerprint: C98E ABD9 5B21 3397 4778 19CE C255 029C F277 FFD0

(Use of my previous key, id E0D421A5 is deprecated.)

The OpenPGP standard specifies four types of signatures on public keys, numbered from 0×10 to 0×13. These are listed in the Signature Types section of the standard. (Different programs may represent these levels differently–GnuPG displays nothing for 0×10 and numbers 0×11 through 0×13 as 1 through 3. KGpg implies a keysigning policy that is roughly equivalent to my own.)

I have certain criteria I use for each level of certification I use on public keys:

  • 0×10 Uncategorized. This signature was made before GnuPG gained support for specifying the level of certification.
  • 0×11 Very casual certification: This signature was made on a key of someone who presented casual identification as the named keyholder. The email address in the uid appears to go to the named keyholder, or the attached photo seems to be the person. I checked at least one photo ID; Driver’s License, Passport, Military ID, etc.
  • 0×12 Personal knowledge of the keyholder. This signature was made on a key belonging to someone I have known personally for long enough that I’m reasonably sure of their identity. I have personally verified that the e-mail address certainly goes to the keyholder.
  • 0×13 Extremely high trust in the keyholder’s identity. I have not yet used this level of certification on anyone else’s keys. In order for me to do so would require that I do extensive research on the person to verify their identity. I do not anticipate ever doing this, so for the moment, the only keys signed with this level of certification will be my own.
