AWS Secret Key
This key is just like a password. Before performing any operation, a user must provide these two keys as authentication keys. Technically, Amazon takes a “signature” as header information for authentication. This “signature” is nothing but an encrypted key, which is a combination of access key and secret key.
It may be possible that user, who has an S3/ SimpleDB account, can have one access key and more than one secret key, so that other users, to whom the owner wants to give, may access his or her account access permissions.
While connecting to Amazon SimpleDB by using SDB Explorer, you must furnish these two keys. After furnishing these two authentication keys, click on go button, to allow the system to check the authentication process, whether the keys are valid or not and later give appropriate message.
