Updates an alias to map it to a different key.
An alias is not a property of a key. Therefore, an alias can be mapped to and unmapped from an existing key without changing the properties of the key.
An alias name can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). An alias must start with the word "alias" followed by a forward slash (alias/). An alias that begins with "aws" after the forward slash (alias/aws...) is reserved by Amazon Web Services (AWS).
The alias and the key it is mapped to must be in the same AWS account and the same region.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginUpdateAlias and EndUpdateAlias.
public abstract Task<UpdateAliasResponse> UpdateAliasAsync( String aliasName, String targetKeyId, CancellationToken cancellationToken )
String that contains the name of the alias to be modified. The name must start with the word "alias" followed by a forward slash (alias/). Aliases that begin with "alias/aws" are reserved.
Unique identifier of the customer master key to be mapped to the alias. This value can be a globally unique identifier or the fully specified ARN of a key. Key ARN Example - arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012 Globally Unique Key ID Example - 12345678-1234-1234-1234-123456789012 You can call ListAliases to verify that the alias is mapped to the correct TargetKeyId.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
