Are MLA archives reproducible ? #229

Closed maaaaz closed 1 week ago

Hello there,

Thanks for this project.

Are MLA archives reproducible ? I haven't tested but if I create 2 times an archive from the same input files, will the archive be exactly the same (hence having the same SHA-512 hash for instance) ?

Because zip ones are not reproducible: https://github.com/drivendataorg/repro-zipfile?tab=readme-ov-file#how-does-repro-zipfile-work

Cheers!

Hello,

Thanks for your interest in MLA.

Unencrypted MLA archives are reproductible as we don't use metadata such as files timestamp creation or modification like ZIP ones. Obviously, encrypted ones, with a generated symetric key for data encryption for each one are not.

I hope I've answered your question, do not hesitate to reopen the issue otherwise.
