Exporting all Versions of a Versioned Key

You can export the default version, a specific version, or all key versions.

To export all versions of a versioned key:

1. Call the ExportKey method of the NaeKeyManagement class.

2. Pass key name, a boolean, and KeyType. You can export both the symmetric and asymmetric keys.

For example:

NaeKeyManagement nkm = new NaeKeyManagement(session);
VersionedKey[] arrVerKeys = nkm.ExportKey("Example_Rijndael_key",true,NaeKeyManagement.KeyType.None);

Enum KeyType is defined as:

public enum KeyType
{ 
    Public = 0,
    PublicPrivate = 1,
    None = 2
}

For symmetric keys, use KeyType.None.

For asymmetric keys, use KeyType.Public to get only the public key, and use KeyType.PublicPrivate to get both the public and private components.

The return type of an ExportKey is an array VersionedKey[]. The VersionedKey class consists of the following properties to store the key bytes of a particular version.

int Version;
byte[] KeyBytes;
