/*-
|
|
* If http_received_header_encrypt is configured, the IP address and the
|
|
* host name of the added Received: header is encrypted with 3DES, to
|
|
* protect information that some could consider sensitve, yet their
|
|
* availability is a must in some circumstances.
|
|
*
|
|
* Such an encrypted Received: header might look like:
|
|
*
|
|
* Received: from DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ==
|
|
* [my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4]
|
|
* with HTTP/1.1 (POST); Thu, 14 May 2009 19:17:28 +0200
|
|
*
|
|
* In this example, the two encrypted components are the sender host name
|
|
* (DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ==) and the IP
|
|
* address (my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4).
|
|
*
|
|
* Using this tool, they can be decrypted into plain text:
|
|
*
|
|
* $ bin/decrypt_received.php 'my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4' \
|
|
* > 'DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ=='
|
|
* 84.3.187.208
|
|
* 5403BBD0.catv.pool.telekom.hu
|
|
* $
|
|
*
|
|
* Thus it is known that this particular message was sent by 84.3.187.208,
|
|
* having, at the time of sending, the name of 5403BBD0.catv.pool.telekom.hu.
|
|
*
|
|
* If (most likely binary) junk is shown, then
|
|
* - either the encryption password has, between the time the mail was sent
|
|
* and `now', changed, or
|
|
* - you are dealing with counterfeit header data.
