Mar 03, 2020  Cloud IoT Core supports the RSA and Elliptic Curve algorithms. For details on key formats, see Public key format. Generating an RSA key. You can generate a 2048-bit RSA key pair with the following commands: openssl genpkey -algorithm RSA -out rsaprivate.pem -pkeyopt rsakeygenbits:2048 openssl rsa -in rsaprivate.pem -pubout -out rsapublic.pem. Oct 02, 2019  The sample application shows an example how to generate a key pair into a context ( rsa or ecp ). Once you have the relevant context, you can use this context to write both the public key and the private key in PEM format, using mbedtlspkwritepubkeypem and mbedtlspkwritekeypem. Generating keys using OpenSSL. There are two ways of getting private keys into a YubiKey: You can either generate the keys directly on the YubiKey, or generate them outside of the device, and then importing them into the YubiKey. Reasons for importing keys include wanting to make a backup of a private key (generated keys are non-exportable. OpenSSL can generate several kinds of public/private keypairs. RSA is the most common kind of keypair generation. Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen.

Openssl Rsa Key Pair Generation 1

You need to programmatically create a public/private key pair using the RSA algorithm with a minimumkey strength of 2048 bits. The method you use to generate this key pair may differ depending onplatform and programming language. Express 2010 server generated keys are not supported.

Generating a public/private key pair by using OpenSSL library

The steps below are an example of the process for generating a public/private key pair for key exchange,using OpenSSL. To execute the following commands, you will need an OpenSSL runtime installed (whichyou can download and install from the OpenSSL website, or install one from your operating system’spackage management system).

Openssl Key Pair Generation

1. Generate an RSA key pair with a 2048 bit private key, by executing the following command:
   'openssl genrsa - out private_key.pem 2048'
   The following sample shows the command:
2. Extract the public key from the RSA key pair, by executing the following command:
   'openssl rsa -pubout -in private_key.pem -out public_key.pem'
   The following sample shows the command:

   A new file, public_key.pem , is created with the public key.

3. Follow the instructions in the next (Validating your private key) section to confirm that your key meets the required criteria.

Validating your private key

When a private key has been generated, you can use the following OpenSSL command to verify that theprivate key fits the required criteria.

1. Execute the following command:
   'openssl rsa -in private_key_sample.pem -text'
2. Verify that the first line of the output includes the private key strength:
   Private Key: (2048 bit)
   If the first line of output states “ unable to load Private Key ,” your private key is not a valid RSA private key.
