--- Comment #5 from David Lee <davidlee54498 at gmail.com> ---
The copy of the keychain made after closing out WebKit was roughly the same size, but filled with random bytes of information in place of my history. A sample is also provided below.

This behavior is deeply, deeply disturbing. I never imagined such a disastrous event could happen. It certainly merits investigation on the part of the developers, as even a small percentage of users experiencing this scenario could be a very serious problem.

While I haven't spent enough time reverse-engineering the keychain file format to fully grasp it, I can definitely say that a portion of my keychain, particularly the headers which are critical to having a usable keychain file (and appear to also include some kind of checksum value for the file) have been overwritten. However, I can also confirm that a large portion of the keychain data is still intact.

While I realize that Apple is not responsible for the performance of developmental software like this, I would greatly appreciate it if somebody over at Apple would put me in touch with a Keychain software engineer who might provide more information on the file format and/or how I could achieve at least a partial http://bottomstack.com/best-paper-shredders/ recovery of the critical contents of my keychain. I have some very important information in there and was caught at an inopportune time due to my backup issues.
