 # aeskeyfind
 
-The aeskeyfind rpm package.
-
-This program illustrates automatic techniques for locating 128-bit and
-256-bit AES keys in a captured memory image.
-
-The program uses various algorithms and also performs a simple entropy
-test to filter out blocks that are not keys. It counts the number of
-repeated bytes and skips blocks that have too many repeats.
-
-This method works even if several bits of the key schedule have been
-corrupted due to memory decay.
-
-This package is useful to several activities, as forensics investigations.

aeskeyfind-30_big-files-support.patch

@@ -1,55 +0,0 @@
-Description: Support for files bigger than 4GB
- aeskeyfind has a bug where it fails to process a file larger than 4GB properly.
- Instead it will process only filesize & 0xffffffff. Sign confusion in entropy
- function can also lead to a crash when processing a large file. Finally, on
- 32-bit systems size parameter to mmap would get quietly truncated.
-
- PS. Due to the design limitations the application cannot scan very large files
- on 32-bit systems. This patch doesn't address that limitation, it however makes
- the application fail gracefully if the situation is met.
