+aeskeyfind \- Locates 128-bit and 256-bit AES keys in a captured memory image.
+.SH SYNOPSIS
+.B aesfix
+SCHEDULE-FILE
+.SH DESCRIPTION
+SCHEDULE-FILE
+The aesfix tool corrects bit errors in an AES key schedule read from the specified hex-encoded file.
+.PP
+This program is limited to AES-128 key schedules, and it can only correct unidirectional 1->0
+bit errors.  For the most part it has been optimized for readability
+rather than performance.
+.PP
+The algorithm has these major steps:
+.PP
+1. Given a key schedule containing bit errors, divide the schedule
+   into four 7-bit "slices", each of which should be uniquely
+   determined by its first four bits.
+.PP
+2. For increasing number of errors w to the key (round 0) bytes:
+.PP
+    a. List possible "decoded" values that could have suffered w
+       or fewer unidirectional errors to form the slice.
+.PP
+    b. Consider all the key schedules generated by combinations of
+       these decodings.  If one could have decayed into the key
+       schedule that we're trying to repair, output it and stop.
