[Security] How to use keytool and openssl

certificate security cryptography

I. How to know if a certificate has private key or not

Open the crt or cre file, if in the Property window you see "This certificate has a private key", it has a PK within.

Or, import it into certmgr, if it has a key icon along with the certificate icon, it has PK.

Certificate without PK cannot authenticate users.

II. Import root certificate into java keystore:

  1. keytool -import -keystore "path to default keystore, like '$JAVA_HOME/jre/lib/security/cacerts' " -file 'root certificate path, if has space, must quote with " "'

and in the prompt, type yes/si, depending on the keytool language.

The root path has extensions like .crt, which only has public key. .p12 or .pks is not allowed.

III. List keys in a keystore

  1. keytool -list -keystore "path to your keystore file" -storepass <password>

if you want more info, after -list you can put -v or --verbose to show details.

By default it accepts .jks type keystore. If the keystore is of type pkcs12(with extension .p12 or .pks, you cannot list it without -storetype. Add this to the line above:

  1. -storetype pkcs12

If it's of type PKCS11, it is more complicated.

First, when loading a PKCS11 type keystore, we must specify:

  1. keytool -storetype PKCS11 -keystore NONE

These two parameters must be together and NONE is upper-cased.

Then, I don't know how to specify a provider with name, and I can only do it with -providerclass. And, if a provider is SunPKCS11, it must come with a config file, set in -providerarg path/to/file. This path is better without space. I cannot make it work with space.
The config file is like:

  1. name = SunPKCS11
  2. library=C:\Program Files\OpenSC Project\PKCS11-Spy\pkcs11-spy.dll
  3. showInfo=true

The DLL used here must be that of OpenSC for TAFU card, and Bit4ID for Izenpe card. I cannot use Bit4Id for TAFU. bit4xpki.dll won't do.

At last, there may be some bugs around this:

https://stackoverflow.com/questions/8247115/java-keytool-with-opensc-pkcs11-provider-only-works-with-debug-option-enabled

According to my comment and the answer, showInfo=true, or solt=-1 may be necessary in the config file. And, use Oracle JDK, not Open JDK. And, add -J-Djava.security.debug=sunpkcs11 at last to avoid the bug.

And, -v gives more information for debug.

So, the command that is working is:

  1. keytool -list -providerclass sun.security.pkcs11.SunPKCS11 -providerArg C:\Users\99GU6879\Desktop\sunpkcs11.cfg -keystore NONE -storetype PKCS11 -storepass a11r1sed -v -J-Djava.security.debug=sunpkcs11

The config file:

  1. name = SunPKCS11
  2. library=C:\Program Files\OpenSC Project\PKCS11-Spy\pkcs11-spy.dll
  3. showInfo=true

Still, I got error for TAFU card and FNMT card. So, maybe it only works with Linux .so files. I think DLL files in Windows is not gonna work.

IV. Export certificate into file

First, we need to find the alias of this certificate. Use keytool -list -keystore <file-name> -storepass <password> | grep "keyword" to find it.

What you can see will be like:

  1. ancert-raiznotariales, 22-oct-2010, trustedCertEntry,
  2. ancert_pubv2, 03-feb-2012, trustedCertEntry,
  3. ancert_cnpv2, 03-feb-2012, trustedCertEntry,
  4. ancert_cgn, 02-feb-2012, trustedCertEntry,
  5. ancert_notv2, 03-feb-2012, trustedCertEntry,
  6. ancert_cpe, 02-feb-2012, trustedCertEntry,
  7. ancert_fernv2, 03-feb-2012, trustedCertEntry,
  8. ancert_cdppv2, 03-feb-2012, trustedCertEntry,
  9. ancert_cgnv2, 03-feb-2012, trustedCertEntry,
  10. ancert_fern, 02-feb-2012, trustedCertEntry,
  11. ancert-subnotcorporativos, 22-oct-2010, trustedCertEntry,
  12. ancert-raizderechopublico, 22-oct-2010, trustedCertEntry,
  13. ancert_cncv2, 03-feb-2012, trustedCertEntry,
  14. ancertcnc_v1_2011, 15-ene-2014, trustedCertEntry,
  15. ancertce_v1_2011, 15-ene-2014, trustedCertEntry,
  16. ancert-subnotapersonales, 22-oct-2010, trustedCertEntry,
  17. ancert_cev2, 03-feb-2012, trustedCertEntry,
  18. ancert-subderechopublico, 22-oct-2010, trustedCertEntry,
  19. ancert-subnotsistemas, 22-oct-2010, trustedCertEntry,

If you know the alias, you can print like this:

  1. keytool -list -keystore CAs.jks -storepass giss08 -alias ancert_cev2
  2. ancert_cev2, 03-feb-2012, trustedCertEntry,
  3. Huella Digital de Certificado (SHA1): E1:EA:3C:39:32:3D:C2:1B:FB:D3:51:1E:6E:4F:95:EF:A9:94:F9:CF

Next, use keytool -exportcert to export it. Here I have a root cert so the extension is .crt. For personal certs, we have p12 or pfx.

  1. keytool -exportcert -keystore CAs.jks -storepass giss08 -v -alias ancert_cev2 >> ancert.crt

(At first I exported it as txt, and opening it I found it is encoded hexdecimally, so I think it is a binary file, and change its extension.)

keytool -printcert is for files, not for exporting cert. After getting this file, we can print it to get a verbose/readable form:

  1. keytool -printcert -file ancert.crt

What we have is:

We can also export it to a pem file with:

keytool -exportcert -alias ancert_cev2 -keypass giss08 -keystore CAs_163_org.jks -rfc -file ancert-cert-para-empleados-v2.pem

What we get is a trusted entry, not a root neither a personal certificate.

Then, to read what we have in the pem file, we have openssl:

openssl x509 -in ancert-cert-para-empleados-v2.pem -text -noout

We can get something like:

We cannot read crt file with this command. It will say:

unable to load certificate
4294956672:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:701:Expecting: TRUSTED CERTIFICATE

By this way, we get only certificate info, and no private key info is exported. And it works only with trusted entries. Normally, we use:

keytool -importkeystore -srckeystore foo.jks \
   -destkeystore foo.p12 \
   -srcstoretype jks \
   -deststoretype pkcs12

openssl pkcs12 -in foo.p12 -out foo.pem

This does not work with trusted entries, is a limitation of PKCS 12 format.

V. Connect to site with openssl

We have:

openssl s_client -connect redp.seg-social.es:443 -cert ancert.pem

This pem file must contain private key info.

When we connect, we can see the certificate chain:
