Title: ssl_generate_keyring_material not enough data to generate key (0x17 required 0x37 or 0x57)
Hello,
I'm trying to find out about a nasty bug in MS IE6 (and probably other IE versions).
The URL https://server.arctis.at is not accepted in IE6. I get a "Die Seite kann nicht angezeigt werden" Error " (This page cannot be displayed).
In Firefox this page is working well.
Not finding any applicable hints in Google, I tried to analyze the problem with wireshark.
I have deposited the private RSA-Key in Wireshark, and tried to decrypt the http-communication.
However the decryption fails.
I tried both the stable and the development (1.1.2) release.
The development release writes into the logfile a line with
ssl_generate_keyring_material not enough data to generate key (0x17 required 0x37 or 0x57)
which seems for me the key problem for decryption.
I have this problem both for firefox and IE communication. Therefore it seems not to be the cause of the IE problem, but rather a problem with my configuration or with wireshark.
So my question is:
What could I do, to get a correct decryption?
I attach the sslDebug.log
Thank you for your help
Michael
