How to decrypt the encrypted SD card

[AC Question]

Hi,
My Android phone has suddenly stopped recognizing my SD card. My phone was encrypted using android's native encryption. Incidentally my phone is still fully functional except for the fact that SD card is not getting recognized.

Is there any way to recover data from SD card (probably by downloading encryption keys from android phone)?

Thanks a lot in advance.

Regards,
Atul

The key is generated by the individual phone randomly, so there's nothing to download. If the phone can't decrypt the card, use your backup. If you didn't back it up unencrypted, there's nothing you can do but format the card and start over.
