Convert IDA signature to code signature and vice versa

ida2sig

Convert IDA signature to code signature and vice versa.

Description

Simple C program for converting an IDA pattern (89 04 24 FF 92 ? ? ? ? 89 34 24) into a code pattern (\x89\x04\x24\xFF\x92????\x89\x34\x24) or vice versa.

The code patterns are meant to be used with a signature scanning library such as 8dcc/libsigscan. See also my Signature scanning in C blog entry.
