【脱壳】【申请邀请码】研究HASP HL Envelope的脱壳

近在研究HASP HL Envelope的脱壳，搜索到一个好用的HASP HL Envelope IAT Fixer，已经成功用于修复我的程序的IAT。原作者为s0cpy。
lostdongle在网上发了一个hasp srm的脱壳视频，里面用的hasp srm Envelope iat fixer和这个一样，仅仅将“find prtc_sec, #FFFF82D18BE55DC3#”，修改为:"find prtc_sec,  #66C1E7??5E5B8BE566C1E6??5DC3#"，这个需要根据hasp srm Envelope 的版本来修改。这段代码对应一个retn的位置（.protect 区段），在这里esp中有需恢复的API函数的地址。

代码:

/*
/////////////////////////////////////////////////////////////////////////////////
HASP_HL Envelop 1.2x/1.3x import resolver script v0.1a
Author: s0cpy
Email : s0cpy.store@gmail.com
OS    : WinXP SP2, Ollydbg 1.1, ODbgScript 1.65.4
Date  : 2008-01-12
                Action: Fix IAT, but not fix emulated functions.
Config: Ignore all exceptions, start from OEP.
Some emulated functions need to be resolved manually:
    GetCommandLineA
    GetProcAddress
    GetCurrentProcess
    GetStartupInfoA
    GetCurrentProcessId
    GetCurrentThreadId
