Change encrypted library to standard

After several years of using encrypted library I need to start sharing files. So I decide to drop encryption. Is there even unofficial way to do it? I didn’t found any info about that. Like decrypt block files on disk (seafile-data folder) and change settings directly in database? Or is there any command? Obviously goal is to keep library history so I cannot just create new library and copy content of encrypted one.

@Jonathan any suggestions? Can you describe how exactly are encrypted libraries work with file block? Is it even possible to workaround seafile scripts?

Currently we have no plan to provide an official way to convert from encrypted library to unencrypted. You can develop a script to do that, based on the information here and the source code.
