In one embodiment, the method includes obtaining, at the external device, an encrypted main key and an encrypted first decryption key from the memory device. The encrypted first decryption key is an encrypted version of a first decryption key. The encrypted main key is an encrypted version of the main key. The external device is unable to read the main key from the memory device. The method further includes decrypting, at the external device, the encrypted first decryption key using a second decryption key to obtain the first decryption key; and decrypting, at the external device, the encrypted main key of the memory device using the first decryption key to obtain the main key.
