Does anyone know a way to password protect or encrpyt a file that would need a password for write access but not read access?

I need to make is readable without a password but still require one for write access. Don't think its possbile but wanted to ask

Hmm, not sure. I know you can do that with openoffice. But I guess in terms of the file system you could set groups with read access and others with write access. far as I know users wouldn't be asked for password though, just given appropriate access depending on their rights.
There might be ways of doing it though.

The permissions solution wouldn't work. there are other users that would have the same permissions to the file but i dont want them to be able to write to it.

What monsm was suggesting was creating a new group for the users that should have write access to the file.

Root has to be the owner and a few people have sudo access to root. Thats why it wont work.
also i dont even want root to edit the file without the proper password

If there is a way to use encryption with 2 seperate keys. 1 for read-only and 1 for read-write that would work but i dont think there is cause of the way encryption works
