Creating Client Keystore and Certificate(3.3)

After generating the key pair for server, the next step is to generate a key pair for the client.

Run the following command:
```
$ keytool -genkey -alias client -keyalg RSA -keystore ./Client.jks -storetype PKCS12 
```
alias = name of the key, for example, client
keystore = name of the keystore, for example, Client.jks
Note!

When prompted for first and last name the hostname where the certificate is valid should be entered, e.g. localhost. Other values can be anything.
Generate a Certificate Signing Request (CSR) so that we can get client's certificate signed by a CA.
```
keytool -certreq -alias client -keystore Client.jks -file Client.csr
```
Get the certificate signed by our the CA, Test CA in these example. See Setting Up a Certificate Authority(3.3) for instructions on how to set up a CA.
```
$ openssl x509 -CA caroot.cer -CAkey cakey.pem -CAserial serial.txt -req -in Client.csr -out Client.cer -days 365
```
Note!

CA, CAkey and CAserial are files generated when setting up the CA.
Import the Test CA root self signed certificate in client key store as a trusted certificate.
```
$ keytool -import -alias TestCA -file caroot.cer -keystore Client.jks
```
Import client's certificate signed by Test CA in client key store with the same alias name that was used to generate the key pair during genkey.
```
$ keytool -import -alias client -file Client.cer -keystore Client.jks
```
We also need to import server's public key in the client key store, because client is the first one who need to initiate a conversation with server or the service. And it needs to encrypt the request message (some part of it) using sever's public key. Server does not need client's public in its keystore if the Binary Security Token is used, server is going to get the client public key in the SOAP message itself.
```
$ keytool -import -alias server -file Server.cer -keystore Client.jks
```
