+# Generate Certificate
+
+If the `test/testdata/test_blob_cert.pem` expire you can generate a new certificate to use in the tests running the
+following command:
+
+```shell
+$ openssl req -key test/testdata/test_blob_private_key -x509 -days 3650 -out cert.pem -new -nodes
+
+You are about to be asked to enter information that will be incorporated
+into your certificate request.
+What you are about to enter is what is called a Distinguished Name or a DN.
+There are quite a few fields but you can leave some blank
+For some fields there will be a default value,
+If you enter '.', the field will be left blank.
+-----
+Country Name (2 letter code) []:US
+State or Province Name (full name) []:CA
+Locality Name (eg, city) []:SF
+Organization Name (eg, company) []:Company
+Organizational Unit Name (eg, section) []:Unit
+Common Name (eg, fully qualified host name) []:www.example.org
+Email Address []:email@email.com
+```
+
+and then you replace the old `test/testdata/test_blob_cert.pem` with the new certificate.
