A device may identify an image to be encrypted, and may convert the image to a first string in a first format. The first string may represent the image. The device may receive information that identifies a key for encrypting the first string, and may generate a first encrypted string by encrypting the first string using the key. The device may convert the first encrypted string, in the first format, to a second encrypted string in a second format. The device may provide the second encrypted string to a storage device without providing the key or the image to the storage device. The storage device may be unable to recover the image using the second encrypted string.
