Decrypting Encrypted Micro SD Card without phone
I don't think the purpose is to allow any decryption of the SD card without using the phone were it was encrypted. Or you could just add specific files to the cloud so that you don't have to worry about retrievable situations, in most cases people tend to use the cloud for photos and video, especially with the space it gobbles up, having 16gb 60gb worth of files on an SD card is pretty risky vs storing it in the cloud, but to answer your question you need to find it the encryption specifically serves the purpose of preventing the decryption unless the content is being decrypted from that parochial device
