I'd like to store information in an org page that gets automatically encrypted when I save it, and decrypted when I open it. Is
there some built-in functionality or hooks for this?

Thank you,

see org-crypt http://orgmode.org/worg/org-tutorials/encrypting-files.html

Here is the setup I have that worked when I tried it last ;)

;; encryption
(require 'epa-file)
(unless (memq epa-file-handler file-name-handler-alist)
  (epa-file-enable))

(require 'org-crypt)
(org-crypt-use-before-save-magic)
(setq org-tags-exclude-from-inheritance (quote ("crypt")))
;; GPG key to use for encryption
;; Either the Key ID or set to nil to use symmetric encryption.
(setq org-crypt-key "some-key")

Thanks, John! I'll give it a try.

Check org-crypt.el (http://orgmode.org/manual/org_002dcrypt_002eel.html)

An alternative to using org's own encryption facility, as others have
suggested, is to encrypt the file as a whole and let emacs worry about
it.

If you create an encrypted file (say using gnupg on the command line)
with the following first line:

# -*- mode: org; epa-file-encrypt-to: ("your key name/email"); version-control: nil; -*-

then opening the file will start it up in org mode and will encrypt on
saving.

I prefer this in some cases although I do also use org's capabilities
for some sections in a file.

Thanks! This might be the best solution, since it's really just one file I want to encrypt/decrypt.

If you want to encrypt all the contents of a file, this is indeed the
best approach, I think.  If you only want to encrypt a small part, then
org's crypt features are better.  The latter, however, become clumsy to
use when the whole file is to be encrypted.

Do you remember what are those 2 lines for?

They are basically copied from thetop of
http://orgmode.org/worg/org-tutorials/encrypting-files.html

The first line loads epa-file (epa-file.el --- the EasyPG Assistant,
transparent file encryption )

The second line looks like a way to call epa-file-enable if it hasn't been
enabled. You can just call epa-file-enable, and it does the check too, but
this probably avoids a minibuffer message when it is already loaded. I
think this function provides a handler for files ending in .gpg which need
to be en/decrypted by gpg.

It simply because it Just Works (TM) with those 3 lines which I have in
my .emacs file:

--8<---------------cut here---------------start------------->8---
  ;; EasyPG Assistant
  (with-eval-after-load "epa-file"
    (setq epa-file-encrypt-to "john-Ch9RrZxMC0c@public.gmane.org")
    (setq epa-file-cache-passphrase-for-symmetric-encryption t))
--8<---------------cut here---------------end--------------->8---

Best regards,
  Seb

You could save the file as .gpg, and put as its first line

# -*- mode: org-mode -*-

By the way if you want to store passwords, take a look at 
org-passwords in /contrib

In my setup (and I didn't do anything special, just installed gpg from
Ubuntu repos), it is enough to name the file foo.org.gpg (of course,
I have this: (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))).
