Question: Can we decrypt a file system using older version

[renjithvrs755]

Hi,

Can we decrypt a file system using an older version than that was encrypted?

I have a specific scenario where the encryption was done by using the 1.9.5 version and the decryption needs to be done by using 1.7.4.
Does this scenario work?

More details:

EncFS 1.9.5
Version 6 configuration; created by EncFS 1.9.5 (revision 20100713) Filesystem cipher: "ssl/aes", version 3:0:0 (using 3:0:2) Filename encoding: "nameio/block", version 4:0:0 (using 4:0:2) Key Size: 256 bits Using PBKDF2, with 243692 iterations Salt Size: 160 bits Block Size: 4096 bytes, including 16 byte MAC header Filenames encoded using IV chaining mode. File holes passed through to ciphertext.

EncFS 1.7.4
Version 6 configuration; created by EncFS 1.7.4 (revision 20100713) Filesystem cipher: "ssl/aes", version 3:0:0 (using 3:0:2) Filename encoding: "nameio/block", version 3:0:0 (using 3:0:1) Key Size: 256 bits Using PBKDF2, with 117782 iterations Salt Size: 160 bits Block Size: 4096 bytes, including 16 byte MAC header Filenames encoded using IV chaining mode. File holes passed through to ciphertext.

Please share your thoughts.
Thanks

Those are two different filesystems. But yes, as long as they are compatible, you should be able to encrypt using a version and decrypt using a different one.
