As far as I could check at grub source code, there is a lib (lib/libgcrypt-grub/cipher/rijndael.c), that implements this algorithm, for encryption and decryption.
Is there any existing command that I could do this decryption? (I tried but didn't find anything like this. Just partitions decryption seems to be supported, not files decryption.)
I was able to compile grub and insmod the gcry_rijndael.mod, but was not able to do anything with this mod (command). Is there any dependence this mod need to have installed to make something?
Thanks and Regards
