Gidon Gershinsky commented on ARROW-8040:
-----------------------------------------

Thanks. I agree the decryption part is much safer than encryption. Regarding 
interop - this decryption code will not be able to read files, produced by 
Spark, because that would require parsing the key material. Implementation of 
key material parsing means implementation of the high level layer. I'll send a 
mail to the list to check if this can be indeed be moved out of a state of 
limbo.
