Notes

• For the latest information about this command, see the official website of OpenSSL.

• To use this command in Windows, you need to set the OPENSSL_CONF environment variable on the console that executes the command. Specify the OpenSSL definition file name by using its full path for the OPENSSL_CONF environment variable. JP1/Base provides the OpenSSL definition file in the following folder:

  In the 32-bit version of Windows:

  installation-folder\ssl\32mt\ssl\openssl.cnf

  In the 64-bit version of Windows:

  installation-folder\ssl\64mt\ssl\openssl.cnf

  However, you must not set the OPENSSL_CONF environment variable for the user environment variable and system environment variable. Set the OPENSSL_CONF environment variable in either of the methods described below. Note that both methods are described on the assumption that the OS is the 32-bit version of Windows. For the 64-bit version of Windows, replace the storage folder of the OpenSSL definition file, for example, as necessary.

  • Setting method by creating a batch file

    Create a batch file to set the OPENSSL_CONF environment variable and execute openssl.exe, and then execute the batch file on the console.

    The contents of the batch file are as follows:

    --------------------------------------

    @echo off

    set OPENSSL_CONF=installation-folder\ssl\32mt\ssl\openssl.cnf

    "installation-folder\ssl\32mt\bin\openssl.exe" %*

    exit /b %ERRORLEVEL%

    --------------------------------------

    Do not enclose the full path to be set in the OPENSSL_CONF environment variable by using double quotation marks ("").

    In the following execution example, the batch file name is sslexe.bat.

    sslexe.bat x509 -text -noout -in jp1basessl.pem

  • Setting method by executing the set command on the console

    Execute the set command that is used to set the OPENSSL_CONF environment variable on the console. An example of executing the set command is as follows:

    set OPENSSL_CONF=C:\Program Files (x86)\Hitachi\JP1Base\ssl\32mt\ssl\openssl.cnf

    Do not enclose the full path to be set in the OPENSSL_CONF environment variable by using double quotation marks ("").

    After executing the set command, execute openssl.exe.

Examples

The following shows examples of executing the openssl command.

To create a private key jp1basesslkey.pem in RSA format:

openssl genrsa 2048 -out jp1basesslkey.pem

To create a CSR jp1base.csr:

openssl req -key jp1basesslkey.pem -out jp1base.csr

To check the expiration date of a server certificate jp1basessl.pem:

openssl x509 -text -noout -in jp1basessl.pem

Execution result (excerpts):

Validity
Not Before: Jul 21 01:31:49 2015 GMT
Not After: Jul 18 01:31:49 2025 GMT

Not Before indicates the date and time when the server certificate was issued.

Not After indicates the expiration date of the server certificate.
