SSL Issue
We want to run application api's files on specific port number but we are facing ssl verification on port number. sometime, we also have ssl certificate in our account but ssl certificate not working.
In this case, we need to create openssl certificate csr file and this csr file will be approve our buy ssl company. SSl certificate can create on linux and window system.
Solution:--
Step 1: Install OpenSSL
Open the following link in your web browser: https://wiki.openssl.org/index.php/Binaries
On the table Third Party OpenSSL Related Binary Distributions, there are a few distributions.
Select the "OpenSSL for Windows" and follow the link: https://slproweb.com/products/Win32OpenSSL.html
Scroll to the section “Download Win32 OpenSSL"
Select one of the non-light edition of the installer and download it.
Double click the OpenSSL file using default settings to complete the installation.
Step 2: Set up OpenSSL for usage
In Windows, click Start > Run
In the Open box, type CMD and click OK
A command prompt window appears
Type the following command at the prompt and press Enter: cd \OpenSSL-Win3.
The line changes to C:\OpenSSL-Win32
Type the following command at the prompt and press Enter: set OPENSSL_CONF=c:\OpenSSL-Win32\bin\openssl.cfg
Step 3: Generate a Certificate Signing Request (CSR) using OpenSSL on Windows
In Windows, click Start > Run
In the Open box, type CMD and click OK.
A command prompt window appears
Type the following command at the prompt and press Enter: cd \OpenSSL-Win32\bin.
The line changes to C:\OpenSSL-Win32\bin
Type the following command at the prompt and press Enter: openssl genrsa -out private-key.key 2048.
Type the following command at the prompt and press Enter: openssl req -new -key private-key.key -out csr.txt.
Fill in the required fields:
Country Name: Use the two-letter code without punctuation for country, for example: US or CA.
State or Province: Spell out the state completely; do not abbreviate the state or province name, for example: California
Locality or City: The Locality field is the city or town name, for example: Berkeley. Do not abbreviate. For example: Saint Louis, not St. Louis
Company: If the company or department has an &, @, or any other symbol using the shift key in its name, the symbol must be spelled out or omitted, in order to enroll.
Organizational Unit: The Organizational Unit (OU) field is the name of the department or organization unit making the request. To skip the OU field, press Enter on the keyboard.
Common Name: The Common Name is the Host + Domain Name. It looks like "www.digicert.com" or "digicert.com". DigiCert certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "digicert.com" will receive a warning if accessing a site named "www.digicert.com" or "secure.digicert.com", because "www.digicert.com" and "secure.digicert.com" are different from "digicert.com." Note: Please do not enter an email address, challenge password or an optional company name when generating the CSR.
.A public/private key pair has now been created. The private key (i.e. private-key.key) is stored locally on the computer and is used for decryption. The public portion, in the form of a Certificate Signing Request (i.e. csr.txt), will be for certificate enrollment.
To move the private key and CSR file to a centralize directory (e.g. certificate) from local computer. Type the following command at the prompt and press Enter:
md c:\certificate
move private-key.key c:\certificate
move csr.txt c:\certificate
The CSR file (i.e. csr.txt) is now ready to use for certificate enrollment
To open the CSR file using Notepad via command prompt. Type the following command at the prompt and press Enter: notepad c:\certificate\csr.txt
A new window (i.e. Notepad) opens which contains the information needed to enroll for a certificate
To copy the Certificate Signing Request from Notepad window, click Edit > Select All
Go to Edit again and select Copy
Once the CSR has been copied, proceed to certificate enrollment
