Certificate Signing Request (CSR) generation instructions

August 16, 2012 by Igor Drobot Leave a Comment

Tutorial for Certificate Signing Request (CSR Request) based on the geotrust knowledge base.

Step 1: Generate a Key Pair
Type the following command at the prompt for a non-encrypted key:

1
openssl genrsa -des3 -out ssl.zeldor.biz.key 4096

openssl genrsa -des3 -out ssl.zeldor.biz.key 4096

Note: When prompted for a pass phrase: enter a secure password and remember it, as this pass phrase is what protects the private key. Both the private key and the certificate are required to enable SSL.

Step 2: Generate the CSR

Type the following command at the prompt to generate the CSR based on the generated key:

1
openssl req -new -key ssl.zeldor.biz.key -out ssl.zeldor.biz.csr

openssl req -new -key ssl.zeldor.biz.key -out ssl.zeldor.biz.csr
