I’ll briefly explain how to generate the signature file for a given library in order to import it from IDA Pro and get the library functions identified by the disassembler (which can save you hours from digging into ‘well-known’ functions).
Requirements: FLAIR tools installed.
Execute the COFF parser
> pcf ms32.lib miracl
ms32.lib: skipped 0, total 432
>sigmake miracl miracl
You might get collision errors here:
See the documentation to learn how to resolve collisitions.
: modules/leaves: 9021136/432, COLLISIONS: 382
At this point, just edit the .exc file, remove the comments in the first lines and re-execute the sigmake command.
Now you’ll see a miracl.sig ready to be imported from the FLIRT signatures window in IDA Pro.
