Deploying a PGP Secret Keyring

To upload the Secring:

• Download the current Secring from SCPI tenant -> Monitoring -> Overview -> Manage Security -> Security Material -> Secring download it


• Open the downloaded secring in Notepad / Notepad++


• Copy the newly created secret to the end of this downloaded file


• Upload the file to SCPI tenant Security Material under secring with the common passphrase.

Note : When creating the secret key, you specify a password. There's also the option to have multiple secret keys in a PGP secret keyring (each with a passphrase). When using PGP secret keys for Cloud Integration, all secret keys must have the same passphrase.

Deploying a PGP Public Keyring

To upload the Pubring:

• Download the current Secring from SCPI tenant -> Monitoring -> Overview -> Manage Security -> Security Material -> Pubring download it.


• Open the downloaded Pubring in Notepad / Notepad++


• Copy the newly created Public to the end of this downloaded file


• Upload the file to SCPI tenant Security Material under Pubring

Below screenshot in file end add new key

End to end flow with Encrypt and Decrypt

For Encryption : We need client Public Key and signature our Secret key 

 

 

 

I am using postman to test this. Sent data using postman and check the encrypted and decrypted payload in CPI. I have add payload log after encryption and after decryption  check Response.

After encryption payload

For Decryption : We need our Secret key to Decrypt  and signature  Client Public Key.

 

After Decryption Payload
