Adding certificate chain to p12(pfx) certificate

2019-01-22 21:11发布

I have aplication in java and cxf which connects to WebServices with client certificate.

I got certificates form WebService owner

  • certificate.p12
  • certificate.pem
  • certificate.crt
  • trusted_ca.cer
  • root_ca.cer

I have problem with straightforward converting this p12 certficate to working jks keystore requred by java.

I did this:

keytool -importkeystore -srckeystore certificate.p12 -srcstoretype PKCS12 -destkeystore certificate1.jks -deststoretype JKS -storepass secret
keytool -import -alias root -file root_ca.cer -trustcacerts -keystore certificate1.jks -storepass secret
keytool -import -alias trusted -file trusted_ca.cer -trustcacerts -keystore certificate1.jks -storepass secret

but this jks doesn`t work and I get HTTP response '403: Forbidden' when using this certificate1.jks

However if I import this p12(pfx) certificate to Internet Explorer and then export this certificate from IE to pfx format selecting "Include all certificates in the certification path" checkbox and use:

keytool -importkeystore -srckeystore certificate.pfx -srcstoretype PKCS12 -destkeystore certificate2.jks -deststoretype JKS -storepass secret
keytool -import -alias root -file root_ca_kir.cer -trustcacerts -keystore certificate2.jks -storepass secret
keytool -import -alias trusted -file trusted_ca_kir.cer -trustcacerts -keystore certificate2.jks -storepass secret

Then everything works fine and I can connect to WebService using certificate2.jks.

I found that original certificate.p12(pfx) contains only one entry (Certificate chain length: 1):

keytool -list -keystore certificate.p12 -storepass secret -storetype PKCS12 -v

while certificate.pfx exported from IE with "Include all certificates in the certification path" contains certificate chain with second Trusted CA certificate (Certificate chain length: 2):

keytool -list -keystore certificate.p12 -storepass secret -storetype PKCS12 -v

So to solve my problem I need to have p12 certificate with chain to trusted CA certificate. I can do this by importing p12 to IE and then exporting back with "Include all certificates in the certification path".

How can I do this without IE using keytool or other tool?

Own answer.

I figured out how to do this with OpenSSL:

openssl pkcs12 -in certificate.p12 -out clientcert.pem -nodes -clcerts
openssl x509 -in trusted_ca.cer -inform DER -out trusted_ca.pem
openssl x509 -in root_ca.cer -inform DER -out root_ca.pem
cat clientcert.pem trusted_ca.pem root_ca.pem >> clientcertchain.pem
openssl pkcs12 -export -in clientcertchain.pem -out clientcertchain.pfx
