Keytool Ascendency Examples Coffee - Add Together Thought Ssl Certificate Inward Keystore Truststore
keytool control inwards Java is a tool for managing certificates into keyStore as well as trustStore which is used to shop certificate as well as requires during SSL handshake process. By using keytool command y'all tin give notice create many things but to a greater extent than or less of the nearly mutual functioning is viewing certificate stored inwards keystore, importing novel certificates into keyStore, delete whatever certificate from keystore etc. For those who are non familiar keyStore, trustStore as well as SSL Setup for Java application , Here is a brief overview on What is a trustStore as well as keyStore inwards Java. Both trustStore and keyStrore is used to shop certificate signed past times signer ascendency or CA (Certificate authority), alongside keyStore additionally storing personal certificate for customer which is used during client authentication on SSL handshake procedure if its enable. In this article nosotros volition meet to a greater extent than or less basic event of keytool control inwards Java to uncovering how many certificates nosotros own got inwards keyStore , viewing those certificates, adding novel certificates as well as deleting erstwhile certificates from keyStore or trustStore inwards Java.
How to usage keytool control inwards Java
PATH is laid upwards correctly for Java. If Path is non laid upwards properly it volition complain that non able to uncovering keytool command. Don't worry y'all only ask to add together JAVA_HOME/bin directory inwards your path to larn keytool control working.
keytool control to uncovering how many certificates are inwards keyStore:
This is the showtime event of keytool control which volition demo y'all how many certificates are stored inwards trustStore or keyStore file :
test@nykdev32:/cygdrive/c/Program Files/Java/jdk1.6.0_26/jre/lib/security keytool -list -keystore jssecacerts
Enter keystore password: changeit
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 81 entries
digicertassuredidrootca, 07/01/2008, trustedCertEntry,
Certificate fingerprint (MD5): 87:CE:0B:7B:2A:0E:49:00:E1:58:71:9B:37:A8:93:72
trustcenterclass2caii, 07/01/2008, trustedCertEntry,
above keytool control shows that default keystore jssecacerts, which comes along alongside JRE as well as introduce inwards JAVA_HOME directory on path JAVA_HOME/JRE/lib/security, has 81 certificates inwards it as well as keyStore type is JKS which stands for Java Key Store. One of those certificates are from digicert
Now if y'all desire to meet details of certificates e.g. Common advert (CN) as well as other attribute y'all tin give notice usage next keytool control to persuasion details of certificates stored inwards keyStore inwards Java :
keytool control to persuasion certificate details from keyStore :
test@nykdev32:/cygdrive/c/Program Files/Java/jdk1.6.0_26/jre/lib/security keytool -list -v -keystore jssecacerts
Enter keystore password: changeit
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 81 entries
Alias name: digicertassuredidrootca

Entry type: trustedCertEntry
Owner: CN=DigiCert Assured ID Root CA, OU=www.digicert.com, O=DigiCert Inc, C=US
Issuer: CN=DigiCert Assured ID Root CA, OU=www.digicert.com, O=DigiCert Inc, C=US
Serial number: ce7e0e517d846fe8fe560fc1bf03039
Valid from: Thu November 09 20:00:00 VET 2006 until: Dominicus November 09 19:30:00 VET 2031
Certificate fingerprints:
MD5: 87:CE:0B:7B:2A:0E:49:00:E1:58:71:9B:37:A8:93:72
SHA1: 05:63:B8:63:0D:62:D7:5A:BB:C8:AB:1E:4B:DF:B5:A8:99:B2:4D:43
Signature algorithm name: SHA1withRSA
Version: 3
Now if y'all desire to import whatever certificate into this keystore y'all tin give notice usage next keytool control :
keytool control for adding certificate inwards keystore as well as trustStore :
keytool -import -alias adding_certificate_keystore -file self.cer -keystore jssecacerts
this volition impress certificate details as well as prompt y'all to own got the certificate, i time y'all confirm that past times typing Yes, certificate volition endure added into your keyStore. For verification role y'all tin give notice re run previous keytool control to larn full break of certificate inwards keystore. For event if nosotros run next keytool control , it should impress 82 certificates inwards keyStore :
test@nykdev32:/cygdrive/c/Program Files/Java/jdk1.6.0_26/jre/lib/security keytool -list -keystore jssecacerts
Enter keystore password: changeit
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 82 entries
Another useful keytool control selection is -printcert which prints details of a certificate stored inwards .cer file :
/ keytool -printcert -file test.cer
That's all on to a greater extent than or less basic keytool control example for viewing as well as adding certificates into keystore as well as trustStore inwards Java. I nevertheless prefer a GUI tool for creating keystore as well as managing certificates but keytool is practiced choice because its comes along alongside JDK installation as well as available inwards nearly places.
