openssl pkcs8 -topk8 -inform PEM -outform DER -in dsaprivkey.pem -out r -nocrypt openssl dsa -in dsaprivkey.pem -outform DER -pubout -out rĢ. To export the key into a DER (binary) format you can use the following steps:ġ. The second step actually creates the private key in the file dsaprivkey.pem which should be kept secret. The dsaparam.pem file is not itself a key, and can be discarded after the public and private keys are created. The first step creates a DSA parameter file, dsaparam.pem, which in this case instructs OpenSSL to create a 2048-bit key in Step 2. openssl gendsa -out dsaprivkey.pem dsaparam.pem openssl dsaparam -out dsaparam.pem 2048Ģ. Once generated, you can use these keys (r and r). Step 2 generates the private key in pkcs8 and DER format. Step 1 generates the public key in DER format. openssl pkcs8 -topk8 -inform PEM -outform DER -in rsaprivkey.pem -out r -nocrypt openssl rsa -in rsaprivkey.pem -pubout -outform DER -out rĢ. Some implementations, in particular Java-based, might require DER or PKCS8 which can for example be generated using the following additional steps:ġ. The resulting private key should be kept secret and is used to sign and decrypt data. This example creates a 2048-bit key, which should work for nearly any purpose. This command generates a PEM-encoded private key and stores it in the file rsaprivkey.pem. RSA private key generation with OpenSSL involves just one step: It has been ported to all major platforms and provides a simple command-line interface for key generation. Using OpenSSLĪlthough there are many methods for creating public and private key pairs, the open-source OpenSSL tool is one of the most popular. Here are several different ways to generate the keys and certificate needed by the Google Workspace SSO service. The way you generate keys and certificates often depends on your development platform and programming language preference. You can do this by simply uploading the key or certificate via your Google Admin console. ![]() Once you have a public key or certificate, you would then need to register it with Google. ![]() To use the service, you need to generate the set of public and private keys and an X.509 certificate that contains the public key. The Google Workspace Single Sign-On service accepts public keys and certificates generated with either the RSA or DSA algorithm. Google Workspace offers the Single Sign-On (SSO) service to customers with Google Workspace or Google Workspace for Education.
