Hello,

workbooks using POI HSSF. We can read encrypted workbooks, but is creation of
such workbooks supported?

Yes, encryption support is read-only. Encryption is well documented in MSDN - look at MS-OFFCRYPTO and MS-XLS specifications. I think that it would be easier to implement encryption support for XLSX than for XLS.

I believe the encryption support is currently only read-only. Maxim may
have an idea of how much work write support may be, and we'd love patches
if you did get a chance to implement it!
