- Fixes selection of digest algorithm when using TKTAuthDigest.

v0.10 (2016-12-16)
------------------
- New option TKTAuthDigest allowing selection of the digest algorithm.
  If not configured, the old defaults of SHA1 (for RSA privkey) and DSS1
  (for DSA privkey) will be used.  SHA224, SHA256, SHA384, and SHA512 are
  the additional valid algorithm values.  (Contributed by Jake Buchholz)

v0.9 (09/07/2015)
-----------------
- New option TKTAuthHeader allowing custom header(s) to be used instead
  of a just a Cookie.

v0.8 (06/28/2012)
-----------------
- new option TKTAuthPassthruBasicAuth and corresponding field in ticket
  ("bauth") makes it possible to specify the Basic authorization
  username/password in the ticket (e.g. when reverse proxying to a
  third party system that cannot use mod_auth_pubtkt).
  The credentials can optionally be encrypted in the ticket (AES-128-CBC).


v0.7 (06/04/2012)
-----------------
- TKTAuthPublicKey can now be set per directory/location (it is
  still possible to set a global default key, so existing configurations

  (contributed by Ivo De Decker).

- TKTAuthLoginURL is now optional; if not provided, users without
  a valid ticket will simply get an HTTP forbidden error
  (contributed by Ivo De Decker).

- Added Perl ticket generation module
  (contributed by Assaf Gordon).

- Module now compiles with Apache 2.4.

- Added TKTAuthBadIPURL option
  (contributed by John Wittkoski).

  modifying MAX_UID_SIZE.
