Static access keys compatible with the Amazon AWS API
Static access keys consist of a private key and a key ID used in services with an AWS-compatible API, such as Object Storage.
The user signs a request with the private key and passes in it the key ID from the AccessKey resource. Yandex.Cloud finds the key with the specified ID and uses it to verify the received signature. Since the key is linked to the account, this allows authenticating the user who is performing the operation.
