The following example creates a named key container and adds a signature key pair and an exchange key pair to the container. This example can be run without problem even if the named key container and cryptographic keys already exist.

Note
Generating an RSA Key Pair Problem You want to use RSA to encrypt data, and you need to generate a public key and its corresponding private key. Solution Use - Selection from Secure Programming Cookbook for C and C Book. Oct 05, 2007 Generating Keys. Generating public keys for authentication is the basic and most often used feature of ssh-keygen. Ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a. How to Create a Public/Private Key Pair. The standard procedure for creating a Secure Shell public/private key pair follows. For information on additional options, see ssh-keygen(1). Start the key generation program.
Rsa Key Pair Generation C Definition
An application should not use the default key container to store private keys. When multiple applications use the same container, one application may change or destroy the keys that another application needs to have available. It is recommended that applications use key containers that are linked to the application. Doing so reduces the risk of other applications tampering with keys that are necessary for an application to function properly.
This example demonstrates the following tasks and CryptoAPI functions:
Rsa Key Pair Generation C 1
These operations only need to be performed once for each user on each computer. If the named key container and key pairs have already been created, this sample performs no operations.
Rsa Key Pair Generation
This example uses the following CryptoAPI functions:
Rsa
This example uses the function MyHandleError. The code for this function is included with the sample. Code for this and other auxiliary functions is also listed under General Purpose Functions.
