How to add certificate chain to keystore?

Question

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"

Solution 1

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.

Solution 2

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

I already have certificates in PKCS#7 format. CA have sent me them in email. Certificates were successfully added to keystore by following command: keytool -import -trustcacerts -file certificate.p7b -keystore keystore -storepass <mypasswd> -alias "myalias" Thank you!

Didn't work for me. I'm getting the error: keytool error: java.lang.Exception: Input not an X.509 certificate. The p7p file was created via: openssl crl2pkcs7 -nocrl -certfile cacert.pem -certfile client-cert.pem -out outfile.p7b

The post here: http://stackoverflow.com/a/22028156/1817029 tells that keytool can't import p7p files!

I also could not get keytool to import a p7b file

Worked for me too. To obtain that private key, this other answer was useful: security.stackexchange.com/a/66865/141918

Note that cat will create a broken pem if there is a newline missing at the end of a cert (happened to me). So better check all.pem content afterwards.

Worked for me. Note that MYPASSWORD is not necessarily the same for the store, source- and destination certificate key.

I have been searching for days for this answer. This is what works if you have the cert chain, key, and the certificate itself all in .pem format. Thank you!

thanks a lot, it works for me, but in my case I modify this: -deststoretype JCEKS, because in my code it cannot recognize PKCS12 format
