Generate the JWT token
Full the next steps to generate the JWT token:
Navigate to localhost and the OAuth shopper.
Select Obtain Non-public Key.
Select Obtain.
Generate the general public certificates
Now, generate the general public certificates from the downloaded non-public key, run the next command, and enter the non-public key password.
Use the openssl command to generate the non-public key:
>openssl pkcs12 -in retailer.p12 -out retailer.crt.pem -clcerts -nokeys
Extract the non-public key:
openssl pkcs12 -in retailer.p12 -passin go:notasecret -nocerts -nodes -out retailer.non-public.key.txt
Be sure that to put in openssl and add to the setting path beforehand.
Earlier than utilizing the non-public key whereas configuring the Amazon Kendra knowledge supply, ensure to not use or copy “—–BEGIN PRIVATE KEY—–” and “—–END PRIVATE KEY—–“ within the code. Moreover, take away any empty areas from the non-public key.
Use the generated ClientId, ClientSecret, and personal key to configure the Amazon Kendra AEM knowledge supply.
For OAuth shopper registration, navigate to http://localhost:<port>/libs/granite/oauth/content material/purchasers.html.
Arrange SSL
Full the next steps to arrange SSL:
Create the important thing:
openssl genrsa -aes256 -out <keyFileName>.key 4096
Encrypt the important thing:

Signal the important thing:
openssl x509 -req -days 365 -in <keyFileName>.csr -signkey <keyFileName>.key -out <keyFileName>.crt
Encode the non-public key to der format:
openssl pkcs8 -topk8 -inform PEM -outform DER -in <keyFileName>.key -out <keyFileName>.der -nocrypt
4 recordsdata will likely be generated with file names beginning with <keyFileName>. We use <keyFileName>.crt and <keyFileName>.der in later steps.
