Setting up SSL communications

Before you enable SSL encryption, you must create a private key and a public key to establish a secure communication session.

The following figure shows the procedure to set up SSL communication. Unless otherwise noted, all steps are required. Note that creation of private and public keys requires a dedicated program. You can download a program for creating private and public keys from the OpenSSL website (http://www.openssl.org/).

Creating a private key

A private key is required to create an SSL keypair. The following procedure for Windows 7 creates a private key file called server.key in the c:\key folder.

Before you begin

Download openssl.exe from the OpenSSL website.

Procedure

  1. If the read-only attribute is set, release it from the c:\openssl folder.

  2. Open a command prompt with administrator permissions.

  3. Move the current directory to the folder to which the key file is output (such as c:\key), and execute the following command: 

    c:\key > c:\openssl\bin\openssl genrsa -out server.key 2048
Parent Topic

Creating a public key

A public key has the file extension .csr. It is required to create an SSL keypair. The following procedure is for the Windows 7 operating system.

Before you begin

Download openssl.exe from the OpenSSL website.

Procedure

  1. Open a command prompt with administrator permissions.

  2. Move the current directory to the folder to which the key file is output (such as c:\key). Execute the following command:

    c:\key > c:\openssl req -sha256 -new -key server.key -config c:\openssl\bin\openssl.cfg -out server.csr

  3. Enter the following information in the prompt:

    • Country Name (two-letter code)
    • State or Province Name
    • Locality Name
    • Organization Name
    • Organization Unit Name
    • Common Name

      To create a self-signed certificate, enter the IP address of the SVP. The name you entered here is used as the server name (host name). To obtain a signed and trusted certificate, ensure that the server name is the same as the host name.

    • Email Address
    • Challenge password (optional)
    • Company name (optional)
Example

The following example shows the contents of a command window when you create a public key.

Obtaining a signed certificate

After creating a private key and public key, obtain a signed public key certificate file. You can use any of these methods to obtain a signed certificate file.

Note

When you send a request to a certificate authority, specify the SVPas the host name.

Hitachi recommends that self-signed certificates be used only for testing encrypted communication.

Obtaining a self-signed certificate

To obtain a self-signed certificate, open a command prompt and execute the following command:

c:\key>c:\openssl\bin\openssl x509 -req -sha256 -days 10000 -in server.csr -signkey server.key -out server.crt

NoteThis command uses SHA-256 as a hash algorithm. MD5 or SHA-1 is not recommended for a hash algorithm due to its low security level.

This command creates a server.crt file in the c:\key folder, which is valid for 10,000 days. This is the signed private key, which is also referred to as a self-signed certificate.

Parent Topic

Obtaining a signed and trusted certificate

To obtain a signed and trusted certificate, you must obtain a certificate signing request (CSR), send that file to a Certificate Authority (CA), and request that the CA issue a signed and trusted certificate. Each certificate authority has its own procedures and requirements. Use of this certificate results in higher reliability in exchange for greater cost and requirements. The signed and trusted certificate is the signed public key.

Parent Topic

Uploading a signed certificate

To use SSL-encrypted communication, you must update and upload the private key and the signed server certificate (Public Key) to the SVP.

Before you begin

  • You must have the Storage Administrator (Initial Configuration) role to perform this task.
  • You must be logged into the SVP.
  • A private key (.key file) has been created. Make sure that the file name is server.key. See Creating a private key.
  • The passphrase for the private key (server.key file) is released.
  • A signed public key certificate (.crt file) has been acquired. Make sure that the file name is server.crt. See Creating a public key.
  • The private key (.key file) must be in PEM format. You cannot use DER format.
  • The signed public key certificate (.crt file) must be in X509 PEM format. You cannot use X509 DER format. See Obtaining a self-signed certificate .
  • The passphrase for the private key (server.key file) is released.

Procedure

  1. Close all Device Manager - Storage Navigator sessions on the SVP.

  2. On the management client, open a web browser and enter the following URL to open the Tool Panel dialog box. 

    http://IP-address-or-host-name-of-SVP/cgi-bin/utility/toolpanel.cgi
    GUID-4CFDCFC0-7E81-4336-9328-E944870C3054-low.png

  3. In the Tool Panel dialog box, click Update Certificate Files.

    If SSL communication has been established, the Security Alert dialog box opens before the login dialog box opens. In the Security Alert dialog box, click OK. The Security Alert dialog box closes and the Login dialog box opens.

  4. In the Login dialog box, enter the administrator user ID and password, and click login. The Upload dialog box opens.

  5. In the Upload dialog box, enter the public key certificate file name in the Certificate file box and the private Key file name (server.key file) in the Key file box. You can enter the file names directly or by clicking Browse.

  6. In the Upload dialog box, click Upload. A confirmation dialog box opens.

  7. Click OK to begin the certificate update. When the update is complete, the SVP web server restarts.

    Depending on the environment, the SVP web server can take 30 to 60 minutes to restart. When it takes that long, an internal server error occurs, and the update completion dialog box does not display. However, the certificate update is complete.

    It can take 30 to 60 minutes for the web server to restart. After the SVP restarts, the Completion dialog box does not appear. Instead, an "internal server error" message is displayed. However, the setting is actually completed.

  8. In the error message box, click OK. If the Security Alert dialog box for the certificate opens, click View Certificate to display the certificate. Confirm that the certificate is correct, and click Yes.

    NoteIf an error occurs during the certificate update, an error message displays. Resolve the problem described in the error message and then repeat this procedure, starting with Step 4 (login) above.

Releasing an SSL certificate passphrase

An SSL certificate cannot be applied for the SVP if the passphrase is set. If the passphrase is set, release the passphrase for the SSL certificate before applying the SSL certificate to the SVP. The following procedure explains how to verify and release the passphrase settings.

Before you begin

  • A private key (.key file) has been created.
  • OpenSSL must be installed. In this procedure, it is installed in C:\openssl.

Procedure

  1. Open a command prompt window with administrator permissions.

  2. Move the current directory to the folder (for example, C:\key) where the key file is stored, and run the following command:

    CautionExecuting this command will overwrite the current key file. To prevent loss of the key file, do one of the following:
    • Back up the key file first.
    • Use a different key file input destination and output destination. 
    C:\key>C:\openssl\bin\openssl rsa -in key-file-input-destination -out key-file-output-destination

    If Enter pass phrase for server.key: is displayed, the passphrase is set. Enter the passphrase. The passphrase in the SSL private key will be released, and the SSL certificate can be applied to the SVP.

Example (when passphrase is set) 
C:\key>c:\openssl\bin\openssl rsa -in server.key -out server.key
Enter pass phrase for server.key: "Enter passphrase"

Converting the SSL certificates to PKCS#12 format

Uploaded SSL certificates need to be in PKCS#12 format.

If you are uploading a created private key and the SSL certificate to the management client, you need to convert the SSL certificate to PKCS#12 format. If you are not uploading the SSL certificate, conversion is not required.

Before you begin

  • You must store a private key and SSL certificate in the same folder.
  • In the following procedure:
    • The private key file name is “client.key”.
    • The SSL certificate file name is “client.crt”.
    • The SSL certificate in PKCS#12 format is output to c:\key.

Procedure

  1. Open a command prompt with administrator permissions.

  2. Enter the following command: C:key>c:\openssl\bin\openssl pkcs12 -export -in client.crt –inkey client.key -out client.p12

  3. Enter a password, which is used when uploading the SSL certificate in PKCS#12 format. You can use up to 128 alphanumeric characters and the following symbols: ! # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~

  4. The client.p12 file is created in the C:\key folder. This client.p12 file is the SSL certificate in PKCS#12 format.

  5. Close the command prompt.
