+DokuWiki plugin Encrypted Passwords
+=======================
+By Wolfgang Reszel
+
+This plugin let you store 256 bit AES encrypted passwords in your DokuWiki pages. The password can be decrypted by clicking them (Javascript must be enabled). Based on the encryption library by Vincent Cheung (http://www.vincentcheung.ca/jsencryption) which incorporates the Gibberish AES library by Mark Percival (https://github.com/mdp/gibberish-aes).
