Our next Keysigning Party is scheduled for Wednesday, September 20, 2017 at MIT Building E-51, Room 315.
MIT Building E-51, Room 315, Wadsworth Street, Cambridge, MA
Wednesday, September 20, 2017 from 18:30 to 21:00
How to Participate
- Create a PGP or GnuPG key, if you don't already have one;
- Post your key to pgp.mit.edu;
- Add your key to the signup list for the upcoming BLU Keysigning;
- Show up at the meeting with proper identification, to verify other participants' identities and to allow them to verify yours;
- After the meeting, sign the keys of participants who have proven their identity to your satisfaction.
To sign someone's key using GnuPG (example uses key ID D5C7B5D9):
- Retreive their key from the keyserver:
gpg --keyserver pgp.mit.edu --recv-keys D5C7B5D9
- Sign the key:
gpg --sign-key D5C7B5D9
- Export the key to an ASCII-armored text file:
gpg --export -a -o D5C7B5D9-exported.asc D5C7B5D9
- Sign and encrypt the exported file so that only the key owner can read it:
gpg -sear D5C7B5D9 -o D5C7B5D9-signed.asc D5C7B5D9-exported.asc
- Email the signed file (D5C7B5D9-signed.asc) to the key owner.
Our next PGP/GnuPG Keysigning Party will be held on Wednesday, September 20, 2017. A key signing party is a get-together of people who use the PGP encryption system with the purpose of allowing those people to sign each others keys. Key signing parties serve to extend the web of trust to a great degree. Key signing parties also serve as great opportunities to discuss the political and social issues surrounding strong cryptography, individual liberties, individual sovereignty, and even implementing encryption technologies or perhaps future work on free encryption software.
The purpose of the meeting is to authenticate each other, i.e. verify everybody's key ids and key fingerprints. Participants sign each others' keys offline.
In order to complete the keysigning in the allotted time, we follow a formal procedure as seen in V. Alex Brennen's "GnuPG Keysigning Party HOWTO". It is strongly advised that if you have not been to a keysigning party before, you read this document.
It is essential that, before the meeting, you register on the signup form listed in the attachments. You should bring at least one picture ID with you. You must also bring your own printout of the report on that page, so you can check off the names/keys of the people you have personally verified.

Script to sign keys
The recommended tool for signing keys post-keysigning party is "caff", which can be installed on debian, Ubuntu, Fedora, CentOS, or Red Hat systems via one of
sudo apt-get install signing-party
sudo yum install pgp-tools
sudo dnf install pgp-tools
For Red hat and CentOS systems, the pgp-tools package is in the optional EPEL repo.
