To get the issuer hash in nginx, you can follow these steps:

1. Enable the ssl_certificate directive in your nginx configuration to specify the location of your SSL certificate file. For example: ssl_certificate /path/to/ssl_certificate.crt;
2. Reload or restart nginx to apply the configuration changes.
3. Run the following command to extract the issuer hash from your SSL certificate file: openssl x509 -in /path/to/ssl_certificate.crt -noout -issuer_hash Replace /path/to/ssl_certificate.crt with the actual path to your SSL certificate file.
4. The output of the above command will be the issuer hash.

Note: Make sure you have the OpenSSL utility installed on your system to run the openssl command.

If you are using Let's Encrypt or a similar certificate authority, you can find the issuer hash in the chain.pem file. This file contains the intermediate certificate and the root certificate used to sign your SSL certificate.

To find the issuer hash in the chain.pem file:

1. Locate the chain.pem file on your server. If you are using Let's Encrypt, it is typically found in the /etc/letsencrypt/live/yourdomain/ directory.
2. Run the following command to extract the issuer hash from the chain.pem file:

1

openssl x509 -in /path/to/chain.pem -noout -issuer_hash

Replace /path/to/chain.pem with the actual path to your chain.pem file.

1. The output of the above command will be the issuer hash.

By following these steps, you will be able to obtain the issuer hash in nginx.
