$yourSecret = "Hello Octopus!" # Place your secret here

$octopusPublicKey = "MIIDnzCCAwigAwIBAgIJAK5yFHmnxrYxMA0GCSqGSIb3DQEBBQUAMIGSMQswCQYDVQQGEwJBVTEMMAoGA1UECBMDUUxEMREwDwYDVQQHEwhCcmlzYmFuZTEhMB8GA1UEChMYT2N0b3B1cyBEZXBsb3kgUHR5LiBMdGQuMRcwFQYDVQQDEw5PY3RvcHVzIERlcGxveTEmMCQGCSqGSIb3DQEJARYXaGVsbG9Ab
