Take 2: yubikey-piv-tool

download yubikey-piv-tool from https://developers.yubico.com/yubico-piv-tool/Releases/

generate a CSR:

yubico-piv-tool --pin=123456 --action=change-pin
yubico-piv-tool -a set-chuid
yubico-piv-tool -a verify -a set-chuid -a generate -s 9a -A RSA2048 -o ftd.pub
yubico-piv-tool -s 9a -a verify -a request -S "/CN=frederick.t.damstra@accenturefederal.com/OU=AFS XDR/O=AFS/" -i ftd.pub -o ftd.csr

Sign it:

cd ~/tmp/frederick_t_damstra/ca/intermediae
# path may vary, and i'm not sure why we need the cellar version. Copying duane's notes here.
cp ca.cnf ca.cnf.duanes
vim ca.cnf
# Change orgnaizationName, state, and country to optional
cp yubi.extensions yubi.extensions.duane
vim yubi.extensions
# Remove the san stuff, because we're just going to do it the easy way
/usr/local/Cellar/openssl\@1.1/1.1.1k/bin/openssl ca -config ./ca.cnf -out ~/Downloads/ftd.crt    -extfile yubi.extensions     -infiles ftd.csr

Freds New Attempt at a local cert, no yubikey

# generate a csr with a new key
cd ~/tmp/frederick_t_damstra/ca
openssl req -nodes -newkey rsa:2048 -keyout ftd-20210603.key -out ftd-20210603.csr
# Sign it
cd intermediae
/usr/local/Cellar/openssl\@1.1/1.1.1k/bin/openssl ca -config ./ca.cnf -out ../ftd-20210603.crt -extfile yubi.extensions -infiles ../ftd-20210603.csr
# Convert to something OSX can import
cd ..
openssl pkcs12 -export -clcerts -inkey ftd-20210603.key -in ftd-20210603.crt -out ftd-20210603.p12
# You *do* need a password

Then open keystore, go to "My Certificates", select 'Import items', and import ftd-20210603.p12. Then, doubleclick on the certificate, expand 'trust', and select 'always trust'.

This works! Wrong trust store in keycloak

This might be useful, but not for now
