Decrypting HTC Desire 820 Encrypted Memory Card: Recover Damaged Files with Known Code

Hello,
I have a problem, I had an encrypted system android on HTC desire 820 (phone memory + memory card), unfortunately, the phone fell and went to the service (previously I took out the card). The phone came back from the site and I would like to decrypt the data from the memory card in some way (they are encrypted, the files are visible but they can not be opened - there is an error / file damaged). Of course, I know the code I previously decrypted the phone and phone memory at the phone startup. Can anyone suggest how this can be done ??

I have not encountered any "external" programs for cracking / decrypting the card after a well-crafted scam, maybe someone will enlighten.

But there is an "official" method:
- Rip the entire memory card to the computer, preferably through a card reader, even hidden folders if present, preserving the structure of directories and files.
- Insert the card into the phone
- Format on your phone
- Encrypt phone and card with the same password as before
- Upload files from the computer to the card
- Decrypt from the phone
