If you are interested in using or developing Sequoia, please get in touch. We can be reached on our mailing list, and using IRC.

To send an encrypted email to someone with a sequoia-pgp.org email address, you can lookup their OpenPGP certificate using our WKD, like so:

% sq network fetch neal@sequoia-pgp.org

All certificates are also certified using our OpenPGP CA certificate:

You can use it to verify a certificate as follows:

$ sq network fetch openpgp-ca@sequoia-pgp.org
$ sq network fetch neal@sequoia-pgp.org
$ sq --trust-root 34F9E4B6A0A70BFEC5AE45198356989DF1977575 pki lookup --email neal@sequoia-pgp.org
[✓] 8F17777118A33DDA9BA48E62AACB3243630052D9 Neal H. Walfield <neal@sequoia-pgp.org>: fully authenticated (100%)
  ◯ 34F9E4B6A0A70BFEC5AE45198356989DF1977575 ("OpenPGP CA <openpgp-ca@sequoia-pgp.org>")
  │   certified the following binding on 2022-08-24
  └ 8F17777118A33DDA9BA48E62AACB3243630052D9 "Neal H. Walfield <neal@sequoia-pgp.org>"

To add our OpenPGP CA certificate as a CA for sequoia-pgp.org email addresses, do:

$ sq pki link add --ca sequoia-pgp.org 34F9E4B6A0A70BFEC5AE45198356989DF1977575 "OpenPGP CA <openpgp-ca@sequoia-pgp.org>"
