Is there any way to append a EasyPG encrypted file?

Is there any way to append a EasyPG encrypted file?

Dear all,

I use GnuPG key to encrypt my 'remember' file, but EasyPG does not support appending file.
Is there any way to append an encrypted file?


Best wishes,
Wei-Wei

Not without decoding and re-encoding the file.

I suppose you could come up with some sort of scheme that would
result in a text file with a series of ASCII armored GPG blocks that can be
decoded and concatenated together when read.

I find the following lines in the epa-file.el:

(defun epa-file-write-region (start end file &optional append visit lockname
				    mustbenew)
   (if append
       (error "Can't append to the file"))
   ...

It seems easypg disable the ability intentionally. I don't know how to solve...

I don't understand what to do. Could you say something more?
