@ -209,6 +209,14 @@ encryption or decryption process. It's difficult to tell from this
error message whether the problem is in the client, in the server,
or in between.
In particular, if the network is corrupting data at the TCP level, it
may only be obvious with cryptographic protocols such as SSH, which
explicitly check the integrity of the transferred data and complain
loudly if the checks fail. Corruption of protocols without integrity
protection (such as HTTP) will manifest in more subtle failures (such
as misdisplayed text or images in a web browser) which may not be
noticed.
A known server problem which can cause this error is described in
\k{faq-openssh-bad-openssl} in the FAQ.
