I would like to help if I can in adding support for EncryptionConfig 9
Please let me know if I can provide any data or how to go about determining the keymat

Thanks

@Koumajutsu how hard would it be to add v9 to it? Have you looked into it? I think the repo here is dead, but I have a fork on a gitlab server that I would love to have someone working on, but I do not know enough about v9 to know how to de-encrypt it, other than that it does not use the same per-determined hash I believe.

@tlf30 The hard part would be figuring out the hash I believe. I was already able to determine that it appears to use a Base64 encoding to turn the encrypted data into ASCII text. The problem starts with generating files of known content. I tried making an encrypted empty ladder logic file, and compared it to an unencrypted file and the normally human readable data differs. Plus after doing more digging, it appears that V9 uses a user aware encryption, so another user in the same organization with lower level of authorization cannot access the file. It's possible that a higher level user might, but still, it hints that the hash will be different for each user
