Whenever I come to crypto reversing, my main problem is detecting the libraries.
I'm reversing this delphi program which uses big library (TLBRijndael, TLbBigInt,...).
some stream procedures like SetPos() or GetSize() are identified by IDA. the point is
before starting the main algorithm after calling near 20 library functions the program
throws an exception and skips the rest code. maybe its because of some division zero
or something else. but if I cannot detect the functions I must guess the problem.
have any of you guys tried reversing delphi's big library or know any sig for that?
I remember black-eye had some crypto/big sig but his website doesn't work atm.
googling gave me nothing and even worse the search section acts so weird, it even
returns "no match" for "Assembly" keyword let alone "Delphi" or "TLB"!!
