I have file with chain of certificates - certificate.cer:
subject=/C...
issuer=/C=US/O=VeriSign, Inc...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
subject=/C=US/O=VeriSign, Inc...
issuer=/C=US/O=VeriSign, Inc...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
subject=/C=US/O=VeriSign, Inc...
issuer=/C=US/O=VeriSign, Inc...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
I need to add this chain of certificates to keystore.
What I do:
openssl x509 -outform der -in certificate.cer -out cert.der
keytool -v -importcert -alias mykey -file cert.der -keypass <passwd> -keystore keystore -storepass <passwd> -alias <myalias>
In result I have only 1 certificate in keystore.
But should have 3.
What could be wrong?
SOLUTION:
CA sent me certificates in PKCS#7 format.
I stored them in certificate.p7b file and then successfully added them to keystore by following command:
keytool -import -trustcacerts -file certificate.p7b -keystore keystore -storepass <mypasswd> -alias "myalias"
From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.
I solved the problem by cat'ing all the pems together:
cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD
(keytool didn't know what to do with a PKCS7 formatted key)
I got all the pems from letsencrypt
