I would really appreciate if someone could shed some light on the following issue. I have read the keytool documentation but could not find any hint regarding what could be the problem here.
I created a keystore
keytool -genkey -alias privateKeyName -keyalg RSA -keystore privateKeyName.jks -validity 720 -keysize 1024
I created a certificate request
keytool -certreq -alias privateKeyName -keystore privateKeyName.jks -file certReqFileName.csr
After the signing authority gave me the .cer file, I tried to import it with
keytool –import -alias privateKeyName -file certReqFileName_t_f.cer -keystore privateKeyName.jks
Import fails with
keytool error: java.lang.Exception: Failed to establish chain from reply
I have been stuck on this for some time now so any help would be awesome.
Thanks.
Take a look at the option -trustcacerts, if your CA is listed in the truststore. Additionally you may have to add the CA's intermediate certificates to your keystore, first.

I am using keycloak-8.0.1 in standalone configuration . I am trying to enable SSL/Https for Keycloak server running on my Test machine (A.B.C.D) , token request will be requested from machine (X.Y.Z.P).
(Will there be any CORS/CSRF issue for the generated token , looks like yes ? And will Keycloak over SSL help to solve this?) Nevertheless i require SSL enabling .
So went ahead with https://www.keycloak.org/docs/latest/server_installation/#enabling-ssl-https-for-the-keycloak-server
Step 1 Run command :
keytool -genkey -alias localhost -keyalg RSA -keystore keycloak.jks -validity 10950
...
two files server.key and keycloak.jks got created.
Question : should i used localhost here or better to use IP A.B.C.D of my Test machine? Though documentation says localhost so went ahead with that.
Step 2 Generate a certificate request :
$ keytool -certreq -alias yourdomain -keystore keycloak.jks > keycloak.careq
I can also generate the cert request using localhost/A.B.C.D.
Step 3: Send the cert req created in above step to CA and download the root cert from CA(root.crt) and import using command:
keytool -import -keystore keycloak.jks -file root.crt -alias root
Do i have to skip this step for localhost and if not how to generate root.crt for localhost.
step 4: last step is to import CA generated certificate to keystore
$ keytool -import -alias yourdomain -keystore keycloak.jks -file your-certificate.cer
Question: Now i have only two files generated in very first step "server.key" and keycloak.jks
and from where i should get root.crt and your-certificate.cer ? I tried uploading the ca request to CAcert.org but they dont create certificate for localhost DNS.
I already went through lot of links link1 , link2 , link3 link4 and getting confused
Please help.
Answer 1-
If you are testing this in your local machine you can use localhost but better would be if you are using IP-address or host name
Answer 3
Again if its for your testing you can use Self Sign Certificate only,No need to go to Ads Certificate authority.
Answer 4-
So for localhost or your machine IP simple Create Certificate with the help of keytool
keytool -genkey -alias initcert -ext san=ip:xxx.xxx.xxx.xx -keyalg RSA -keystore keycloak.jks-validity 365 -keysize 2048
Export the certificates
keytool -export -noprompt -trustcacerts -keystore keycloak.jks -alias initcert -file keycloak.cer -storepass changeit
Import Certificates into Client machine Java Keystore
keytool -import -noprompt -trustcacerts -alias "initcert" -file keycloak.cer -keystore /workspace/tools/jdk/java-1.7.0-openjdk-1.7.0.25.x86_64/jre/lib/security/cacerts
I am trying to establish a secure connection for my application using jetty http server version 8.1.8.v20121106 with self signed certificate.
I am generating self signed certificate with the following command,
keytool -genkey -alias mykey -keyalg RSA -keysize 2048 -sigalg SHA256withRSA -validity 365 -keypass password -keystore keystore.jks -storepass password
keytool -export -alias mykey -file server.cer -keystore keystore.jks -storepass password
keytool -import -alias mykey -file server.cer -keystore truststore.jks -storepass password
So, totally 3 files generate (keystore.jks,server.cer,truststore.jks)
After the server gets started, I got the following error in my browser. There are issues with the site's certificate chain (net::ERR_CERT_AUTHORITY_INVALID).
Could anyone help me to generate a trusted self signed certificate using keytool.
Thanks in advance.
It is the problem with java jdk. I have verified using java 1.8 and jdk1.7.0_79 it is working fyn for me. Change your java jdk version and verify. For further clarification, Please refer this link.

Good morning,
I recently requested a certificate from GoDaddy and they have sent me two sets of .pem and .spc files (SHA1 and SHA1) but when I try to import them to my codesignstore it says they are not X.509. Is there any way to convert them?
I used these commands to generate the files that I sent to GoDaddy.
Keystore
keytool -genkey -alias codesigncert -keyalg RSA -keysize 2048 -dname "CN=Corp,O=Corp,C=US,ST=FL,L=Orlando" -keystore codesignstore
Certificate Request
keytool -certreq -v -alias codesigncert -file codesign.pem -keystore codesignstore
Import
keytool –import –alias codesignecert –file NAME_OF_FILE_FROM_GODADDY –keystore codesignstore
I tried importing a trustcert using the below command and it worked for me.
keytool.exe -import -trustcacerts -alias "cert_alias_name" -file cert.pem -keystore "C:/Program Files/Java/jre1.8.0_291/lib/security/cacerts" -srcstorepass changeit -deststorepass changeit -v -noprompt
Certificate was added to keystore
[Storing C:/Program Files/Java/jre1.8.0_291/lib/security/cacerts]
I've been working on a client API using QuickFIX and I'm planning to use SSL and certificate based authentication. I generated self signed certificates for acceptor and initiator the following way:
1) Generate and export server/acceptor certificate:
keytool -genkeypair -keyalg RSA -keysize 2048 -alias server -keystore server.jks
keytool -export -alias server -file server.cer -keystore server.jks
2) Generate and export client/initiator certificate:
keytool -genkeypair -keyalg RSA -keysize 2048 -alias client -keystore client.jks
keytool -export -alias client -file client.cer -keystore client.jks
3) Import server/acceptor certificate to client keystore:
keytool -import -v -trustcacerts -alias server -file server.cer -keystore client.jks
4) Import client/initiator certificate to server/acceptor keystore:
keytool -import -v -trustcacerts -alias client -file client.cer -keystore server.jks
Acceptor config:
SocketUseSSL=Y
SocketKeyStore=server.jks
SocketKeyStorePassword=password
Initiator config:
SocketUseSSL=Y
SocketKeyStore=client.jks
SocketKeyStorePassword=password
Everything seems to work fine and data is getting encrypted. However, if I remove the initiator's client.jks keystore file, I will get a QuickFIX log entry saying "client.jks: keystore not found, using empty keystore". Strange thing, the initiator is still able to connect and establish a valid FIX session. I would expected the connection to be dropped immediately since no valid certificate is provided. Am I missing something?
The client certificate is not required by default, you must set this:
NeedClientAuth=Y
I am using self signed certificate for HTTPS connection to and from Axis2 server. All of these connections works fine and as desired.
There is a part in my web service which is responsible for sending emails. I am using GMail for the purpose of sending mail.
The problem is when I try to send a mail using an SSL connection I get certificate error, i.e. GMail certificate is not trusted. I had faced a similar problem with JBoss as well. For once I was able to get around this problem downloading GMail certificate and than importing it into the Keystore using Keytool utility. For a long time this had worked.
But only recently I have started to get the Old problem again. I tried to use the old technique that fixed the problem last time, but this time that did not work. (not sure why)
I reckon that GMail uses a signed certificate which out of the box should be trusted by any of the servers, let it be JBoss or Axis2. I fail to figure out what the problem actually is. Is it because of using of Self Signed certificate? Or are there any specific way of creating it so that the Signed certificates are trusted?
Thanks for the help.
To have a SSL encrypted Server/Client communication we need to Keystores and Truststore for Server & Client. Following are the steps to create them.
#Creating Server keystore and exporting a certificate
keytool -genkey -alias serverkeys -keyalg RSA -keystore server.keystore -storepass changeit -keypass changeit -dname "CN=test.com, OU=Test, O=Test, L=London, ST=London, C=UK"
keytool -export -alias serverkeys -keystore server.keystore -storepass changeit -file server.cer
#Creating Client keystore and exporting a certificate
keytool -genkey -alias clientkeys -keyalg RSA -keystore client.keystore -storepass changeit -keypass changeit -dname "CN=test.com, OU=test, O=test, L=London, ST=London, C=UK"
keytool -export -alias clientkeys -keystore client.keystore -storepass changeit-file client.cer
#Making a copy of cacerts file. These copies will be used for client/server truststore
cp /usr/java/jdk1.6.0_14/jre/lib/security/cacerts client.truststore
cp /usr/java/jdk1.6.0_14/jre/lib/security/cacerts server.truststore
#Copying server certificate to Client truststore
keytool -import -trustcacerts -v -keystore client.truststore -storepass changeit -file server.cer
#Copying Client certificate to Server truststore
keytool -import -trustcacerts -v -keystore server.truststore -storepass changeit -file client.cer
During the first few iteration I was not using cacert but directly create truststores from the certificate and that too worked well. Problems came up when we need to connect to some other services using SSL and connection could not be establised even when the service used a Signed Certificate.
For example connecting to GMail SMTP server would faile if the truststore were not created up from cacerts. Reason being even though GMail uses a signed certificate, we wold be using a truststore that would not know if the GMail certificate can be trusted. For this reason we used cacerts to create out truststore. After which we were able to connector any service that uses a Signed Certificate.
If in case we encounter a unsigned certificate we will then have to add them to the Components Truststore.
