Compiling .pfx file using openssl

A .pfx file, also known as PKCS #12 or P12 file, is a binary format for storing cryptographic objects. It typically contains:

1. Private Key (.key file)

2. Public Key Certificate (.crt file)

3. CA Certificate Chain (optional)

The .pfx file is commonly used to import and export certificates along with their private keys. It is often required when configuring SSL/TLS for web servers, email clients, or cloud services like Azure or AWS.

Generating .pfx file

Note : You should have the Private Key (.key) file & the CA cert (root.crt) to make the pfx file and the CA-chain(.bundle) if available by the Domain Holder

# openssl pkcs12 -export -out ghoulsec.pfx -inkey ghoulsec.key -in ghoulsec.crt

• Verifying .pfx file

# openssl pkcs12 -info -in ghoulsec.pfx
 -  Enter the passphrase : Admin@123(<defpass>)
 :
 - < EOL > OK
