Key Tool commands 




Keystores and truststores are repositories that contain cryptographic artifacts like certificates and private keys that are used for cryptographic protocols such as TLS.


Keystore:



A keystore contains personal certificates, plus the corresponding private keys that are used to identify the owner of the certificate.

Truststore:


A truststore contains the signer certificates (also known as certificate authority certificates) which the endpoint trusts.


A signer certificate contains a public key, which is used to validate personal certificates. 
By installing the server’s signer certificate into the client's truststore, you are allowing the client to trust the server when it establishes a TLS connection. 
The same principle is true for a server to trust a client when TLS client authentication is enabled.




Generate Key store and self signed in one command :



keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass password -validity 360 -keysize 2048




Generate Key store


keytool -genkey -alias rameshbabuchallablogspot -keyalg RSA -keysize 2048 -keystore rameshbabuchallablogspot.jks


CSR :


keytool -certreq -alias bloggerflare -keyalg RSA -file rameshbabuchallablogspot.csr -keystore rameshbabuchallablogspot.jks


Importing CA Certs:


keytool -importcert -alias root -file root -keystore rameshbabuchallablogspot.jks

or 

keytool -import -trustcacerts -alias root -file Thawte.crt -keystore keystore.jks


keytool -importcert -alias intermediate -file intermediate -keystore rameshbabuchallablogspot.jks


keytool -importcert -file rameshbabuchallablogspot.cer -keystore rameshbabuchallablogspot.jks -alias rameshbabuchallablogspot

IBM WebSphere - Synchronize a node (syncNode)

Image
  IBM WebSphere - Synchronize a node (syncNode) Before we get into synchronization, let's talk about nodes and the master configuration. The master configuration is a collection of XML files that contain all sorts of information about a cell, such as the security settings and the applications in the cell. A node contains one or more WebSphere application servers. When a managed nodes is federated into the dmgr, the node needs to be synchronized with the master configuration so that the node is using the dmgr configuration. The synchronization is always from Dmgr to Nodes and it never happens vise versa. If you made any changes from the node side it will be cleared during next synchronization process. Let's consider a common example. You make some change in the WebSphere admin console, and you are presented wit the Save option. Selecting save updates the master configuration. This will cause the node to be out of sync with the master configuration. To know if a node is synchroni...

Backup and Restore of WebSphere Application Server configuration

                      Backup & Restore of IBM WebSphere Application Server Configuration Backup configuration in  WebSphere One of the major activity that we can perform in Websphere as a pre-requisites when ever we intended to perform any major configuration changes like Fix Pack upgrade ,Interim Fix upgrade, JDK upgrade etc. For any mission critical application, taking frequent backups is essential for recovering from severe errors. In the case of WebSphere Application Server, setting up of the application server environment is a demanding task and it is not an easy to repeat the setup if something bad happens. So, its wise to take backups whenever we make the first setup or when we do configuration changes. Depending upon our diskspace availability two types of backups is possible . 1) Full Backup A full backup can be performed by running the ./backupConfig command from the<WAS-ROOT>/bin di...
