Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public override void FromXmlString(
	string xmlString
)

The FromXmlString initializes an RSA object using key information in an XML string that was generated using the ToXmlString method. The FromXmlString method accepts either an XML string containing a public key or an XML string containing a public and private key.

Use the FromXmlString method to conveniently initialize RSA key information.

Caution noteCaution

Persisting an XML string containing a private key to an insecure location is a security threat. The security of your application can be compromised if a malicious third party can access your private key. To safely persist a private key, use a secure key container. For more information about persisting private keys in a key container, see How to: Store Asymmetric Keys in a Key Container.
