问题 I am going through the exact same process as the answered question found here (Connect a Google CloudSQL Postgres database to Data Studio), but I am not as advanced a user as most. I am encountering a similar problem to what was mentioned in the above question, and then some: I have created a client certificate and downloaded the client-cert.pem, client-key.pem and the server-ca.pem files to my local machine. I received the same error when attempting to link Data Studio to our Google Cloud

阅读更多关于 Connect a Google CloudSQL Postgres database to Data Studio

问题 I am trying to connect a Postgres database hosted in a google Cloud Sql instance to Data Studio. I have followed the instructions (found here https://support.google.com/datastudio/answer/7288010) but to my disappointment, I still cannot connect to the database from Data Studio. I think the problem lies with the SSL connection, as if I enable "non-secure connections" in the options in CloudSql I can successfully connect from Data Studio. I have created the 3 files required for the ssl

OpenSSL's PEM file and Lockbox3 interoperability

阅读更多关于 OpenSSL's PEM file and Lockbox3 interoperability

问题 I have a RSA key in a PEM file created with openssl, and Im trying to load it into Lockbox3 (a delphi component) but it seems they are not compatible. In their forums I found this: "Only after you nail down all the options used by the other party, both explicit and implicit (which are typically poorly documented), do you have a chance for interoperability." So, I'm wondering if someone had made it work. 回答1: The latest version of Lockbox (available from SVN, not the file downloads as yet),

How do I encrypt with an RSA private key read from a PEM file using the Go programming language?

阅读更多关于 How do I encrypt with an RSA private key read from a PEM file using the Go programming language?

How do I do the equivalent of the following C++ code in go? RSA *key = PEM_read_RSAPrivateKey(f, NULL, NULL, NULL); std::vector<CK_BYTE> out(128); RSA_private_encrypt(in.size(), &in[0], &out[0], key, RSA_PKCS1_PADDING) I've looked at the Go rsa package . It looks like EncryptPKCS1v15() may be the equivalent of RSA_private_encrypt(). But I don't see how to create a PrivateKey object other than with GenerateKey(), which (one can confirm by looking at the source ) generates one using random prime numbers. Do I need to figure out how to decode a PEM file so pull out the PrivateKey fields' values?

问题 I am building an oauth 1.0a service that will be consumed by a gadget within Jira, it's a .Net 3.5 Application written in C#. Jira makes requests to this service using the RSA-SHA1 signature method, which means to verify the signature of the request I need create an X509Certificate instance form their public cert. Within the Jira application you can get the public cert by going to the consumer info screen (which also has the consumer key for Jira etc.) and it presents the public key in this
