Any body sees anything wrong in using sn.exe to generate a public / private key pair that I can later use to encrypt data using the private key, then give people the public key so they can decrypt my ciphertext? I know sn.exe is used for strong naming assemblies, but since it generates a key pair. Cryptography/Generate a keypair using OpenSSL. From Wikibooks, open books for an open world. Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen. $ openssl rsa -pubout -in privatekey.pem -out publickey.pem writing RSA key A new file is created, publickey.pem, with the public key. The New-RsaKeyPair function uses the certreq.exe program to generate an RSA public/private key pair suitable for use in encrypting/decrypting CMS messages, credentials in DSC resources, etc. It uses the following.inf file as input (taken from the first example in the help for the Protect-CmsMessage cmdlet).
The Strong Name tool (Sn.exe) helps sign assemblies with strong names. Sn.exe provides options for key management, signature generation, and signature verification.
Warning
Do not rely on strong names for security. They provide a unique identity only.
For more information on strong naming and strong-named assemblies, see Strong-Named Assemblies and How to: Sign an Assembly with a Strong Name.
The Strong Name tool is automatically installed with Visual Studio. To start the tool, use the Developer Command Prompt (or the Visual Studio Command Prompt in Windows 7). For more information, see Command Prompts.
Note
On 64-bit computers, run the 32-bit version of Sn.exe by using the Developer Command Prompt for Visual Studio and the 64-bit version by using the Visual Studio x64 Win64 Command Prompt.
At the command prompt, type the following:
SyntaxParameters
Note
All Sn.exe options are case-sensitive and must be typed exactly as shown to be recognized by the tool.
Remarks
The -R and –Rc options are useful with assemblies that have been delay-signed. In this scenario, only the public key has been set at compile time and signing is performed later, when the private key is known.
Note
For parameters (for example, –Vr) that write to protected resources such as the registry, run SN.exe as an administrator.
The Strong Name tool assumes that public/private key pairs are generated with the
AT_SIGNATURE algorithm identifier. Public/private key pairs generated with the AT_KEYEXCHANGE algorithm generate an error.
Examples
The following command creates a new, random key pair and stores it in
keyPair.snk .
The following command stores the key in
keyPair.snk in the container MyContainer in the strong name CSP.
The following command extracts the public key from
keyPair.snk and stores it in publicKey.snk .
The following command displays the public key and the token for the public key contained in
publicKey.snk .
The following command verifies the assembly
MyAsm.dll .
The following command deletes
MyContainer from the default CSP.
