Re-writing content on save

[Travis Jensen <tr...@gmail.com>]

http://wiki.apache.org/couchdb/How_to_intercept_document_updates_and_perform_additional_server-side_processing
hasn't
been written. I need to save a portion of the document as encrypted. How can
I insert my code in between the put and the actual save (and vice-versa for
reading) to do said encryption/decryption?

Thanks.

For encrypting on write, you can use an update handler, as described here:

For decrypting on read, you can use a show function:
