Openssl Generate Private Public Key Pair
Oct 09, 2019 OpenSSL has a variety of commands that can be used to operate on private key files, some of which are specific to RSA (e.g. Openssl rsa and openssl genrsa) or which have other limitations. Here we always use openssl pkey, openssl genpkey, and openssl pkcs8, regardless of the type of key. @Mawg: Your openssl command is outputting the public key corresponding to the supplied private key - public keys aren't encrypted (they're not secret), so using -passout makes no sense. You probably want to use -passin there, to supply the passphrase that was used to encrypt the private key in the first step. The private key is generated and saved in a file named 'rsa.private' located in the same folder. Generating the Public Key - Linux 1. Open the Terminal. Type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder.

Openssl genrsa -des3 -out private.pem 2048 That generates a 2048-bit RSA key pair, encrypts them with a password you provide and writes them to a file. You need to next extract the public key file. You will use this, for instance, on your web server to encrypt content so that it can only be read with the private key.
To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.
Note
In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.
Create a key pair
To create a key pair, at a command prompt, type the following command:
sn –k <file name>

If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:
Next, extract the public key from the key pair and copy it to a separate file:
Once you create the key pair, you must put the file where the strong name signing tools can find it.
When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.

If you are using an earlier version of Visual Studio that does not have a Signing tab in the project properties, the recommended key file location is the project directory with the file attribute specified as follows:
