You can also use OpenSSL CSR online generator: You must save both the. Key and. CSR files)

If you want to generate a CSR file and apply for a certificate, download the file:

Step 1: Decompress the package to the C: \ OpenSSL directory, execute cmd.exe to enter the command window, and execute:
Cd c: \ OpenSSL
Set openssl_conf = OpenSSL. CNF
OpenSSL req-New-nodes-keyout server. Key-out server. CSR

Therefore, the current directory will generate two files: Server. Key and server. CSR. Keep these two files properly. do not disclose the server. Key Private Key File.
During the command execution, the system requires you to fill in the following information:

Country name (2 letter code): Enter the country code with 2 letters in the format of the ISO country code. Enter CN in China.

Step 6: Set server. Key generated in step 1 and server. CRT generated in step 5 as a pair of certificates and keys. Install the certificate according to the server instructions.

If you want to use the certificate generated by OpenSSL on IIS, You need to merge the. Key and. CRT files into the. pfx file by using the following method:

Run cmd.exe to enter the command window and run:
Cd c: \ OpenSSL
Set openssl_conf = OpenSSL. CNF
OpenSSL PKCS12-export-out server. pfx-inkey server. Key-in server. CRT

In IIS 6, you can import the server. pfx file.
