java - X509 certificate signed with bouncy castle is not valid -

i went quite long way make java sign csr , @ last able this, openssl tells it's not valid. same csr signed openssl passes verification step.

all same x509 version (1), no extensions, subject, issuer same.

i suspect problem subject dn (email especially) or dates.

verification:

  openssl verify -verbose  -cafile src/test/resources/ca.cer.pem o.cer.pem     o.cer.pem: ok     openssl verify -verbose  -cafile src/test/resources/ca.cer.pem client.cer.pem       client.cer.pem: c = ru, st = moscow, l = moscow, o = hoofs, ou = it, cn = danee yaitskov       error 20 @ 0 depth lookup:unable local issuer certificate 

file sizes similar:

1229 jul 28 12:45 client.cer.pem 1233 jul 28 13:00 o.cer.pem

it complains there missing certificate in chain but, don't see such information.

how check next parent certificate?

i have similar example working

try replacing x500name issuer = x500 name got ca avoid problems characters

x500name issuer = x500name.getinstance(cacert.getsubjectx500principal().getencoded()); 

also, think have need part before pem encoding

cmssigneddatagenerator generator = new cmssigneddatagenerator(); signer = new jcacontentsignerbuilder("sha1withrsa").build(cakey); generator.addsignerinfogenerator(new jcasignerinfogeneratorbuilder(new jcadigestcalculatorproviderbuilder().build()).build(signer, cacert)); generator.addcertificate(new x509certificateholder(certencoded)); generator.addcertificate(new x509certificateholder(cacert.getencoded())); cmstypeddata content = new cmsprocessablebytearray(certencoded); cmssigneddata signeddata = generator.generate(content, true); byte signedcertificate[] = signeddata.getencoded();
