Apr 17, 2013 GPG basic file encryption doesn’t required public/private key. But to make a encrypted file more secure you can use RSA/DSA algorithms. These algorithms generates public and private keys to encrypt file. This article will help you to do following three tasks for File Encryption using GPG Key Pair in Linux. Create key pair. Oct 03, 2019 Find out how to create and export a GPG keypair from the macOS command line. And your many duties require you make use of encryption or various tools that depend on GPG public keys.
GNU gpg is encryption and signing tool.
The GNU Privacy Guard (GnuPG or GPG) is a free software replacement for the PGP suite of cryptographic software.
GnuPG encrypts messages using asymmetric keypairs individually generated by GnuPG users. The resulting public keys can be exchanged with other users in a variety of ways, such as Internet key servers. They must always be exchanged carefully to prevent identity spoofing by corrupting public key ↔ ‘owner’ identity correspondences. It is also possible to add a cryptographic digital signature to a message, so the message integrity and sender can be verified, if a particular correspondence relied upon has not been corrupted.
How do I create my own GnuPG private and public key
1) Login to your shell account
2) Use gpg command to create the keys
$ gpg --gen-key Output:
3) Now keys generated, you can list your own key using:
$ gpg -K OR $ gpg --list-keys Output:
Let us try to understand the line pub 1024D/CA7A8402 2007-02-10:
Most important is the key ID i.e. CA7A8402. Make sure you use powerful passphrase to protect keys and not the easy one.
4) To list secret key, type the command:
$ gpg --list-secret-keys Output:
ADVERTISEMENTS
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.
Rsa Generate Key Pair Using Gpg OnlineCreate a key pair
To create a key pair, at a command prompt, type the following command:
Java Generate Rsa Key Pair
sn –k <file name>
Rsa Generate Key Pair Using Gpg 1
In this command, file name is the name of the output file containing the key pair.
The following example creates a key pair called sgKey.snk.
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:
