Various methods and systems for securing access to hash-based storage systems are disclosed. One method involves receiving information to be stored in a storage system from a storage system client and then generating a key. The key identifies the information to be stored. The value of the key is dependent upon a secret value, which is associated with the storage system. The key is generated, at least in part, by applying a hash algorithm to the information to be stored. The key can then be returned the key to the storage system client. The storage system client can then use the key to retrieve the stored information.
