How to use Letsencrypt certificate & private key with Jetty

letsencrypt-jetty.sh

# input: fullchain.pem and privkey.pem as generated by the "letsencrypt-auto" script when run with
# the "auth" aka "certonly" subcommand

# convert certificate chain + private key to the PKCS#12 file format
openssl pkcs12 -export -out keystore.pkcs12 -in fullchain.pem -inkey privkey.pem

# convert PKCS#12 file into Java keystore format
keytool -importkeystore -srckeystore keystore.pkcs12 -srcstoretype PKCS12 -destkeystore keystore.jks

# don't need the PKCS#12 file anymore
rm keystore.pkcs12

# Now use "keystore.jks" as keystore in jetty with the keystore password you specfied when you ran
# the "keytool" command

Omg thanks everybody for your nice comments, glad it was of help! :)

Thanks @juleskers — yeah things have definately improved a lot since the letsencrypt snowballing started :)

Thank you.. That's helped me to figure out how to have the key-certificate thing is done in jetty. It worked with me, though I kept the pkcs12 format and did not convert it to jks.
Actually, I tried first to convert it, but It a warning showed up and advised me to keep using pkcs12.
