hbcxx:使用“#!/ usr / bin / env hbcxx”使C ++源代码可执行-开源
该代码通过异或解密和base64解码得到一个Python代码对象,然后使用marshal模块的loads函数将其转换为可执行的代码对象。最后通过exec函数执行该代码对象。
根据给定的密钥,我们可以使用Sympy库计算出一个积分值,并将其与给定的检查值进行比较,如果相等,则可以进行解密操作。以下是解密代码:
```
import base64
import marshal
encoded_data = b'#VVVVVVVVVVVVVVVVVVVVVSVVVVFVVVV_YZVVVVMVU|VNFV@pU|V{xUMVYvVzBSMVDSVFRVMFDSV\\VQMV@%7fVAxPMFU{V@BPp]vU%B_MF]eVy]VMFY|UxZUVFUbTPBSMVrSVFRVMV%7fCVT|]N^VVVVVVVVVVVVVVVpVVVVPVVVVFVVV_GFVVVVsVU'V@FUpPSVO\'TMV].V$FUMVPSVBFVOC".U_SqV]/UU|VQU/V_RsV]/V^ZUQpVMVUtVMVR@V_'SqV]/Vo|VqV]/UU|VVpU/VyRGVU/VySGVUoPPFTUVU.U_'SsVXSV_'QqVQRVQ&pqFM/UPFSQU|VENVqFE/V$TqVFMVUtVMVR@V_'SqV]/Vo|VqV]/UU|VVpU/VyRGVU/VySGVU/VyTqVFMV_TqVZMVUtVMVR@VU|VqFs/UvVRqVM/U'RVxFRUV_QfqVACVT|RCb|VVFVV!FVVVVSgVFVVVT|Q%pEdvOY'%pAnN@"yMsxSuPAb%p{~rOE{NO]nNOyvUzQtPAbMT|^%pYeMO{vTOUdN@{bsPA#sYxUB.xUvcxUvAx\\N%{vPAnsPA#sYxRN%%7f%7ftcxUv!|Vtp/VVVS!UzM&u~"rsx[tzZ\'O%AbN$]"t_FUVVVVtoVVVVVVFUUV^ZVDVU_V^^VFNTTVRZVEVUPpRNVEVTt%7fRVVVUmTVVVPA#N@&uPAqv%A"tnxVVVSN{U!ez%M\'!&&VP ez!UZmA.\'X"g^\'/NUcvXd.TPRTTD!&UB\\dT.R}Q{!QQUdr~UguyU&sTU"u$An^PMdN@t!rpA&sPNcXQxSr@Am@p]bu\'#gT_^EVVVVtp|VVVUvU@YxM@Ye%pAtz{bsYxQv@"sOCvUzAbN%.|MsxRMzo%7fM&x]M@"}ty{sPA|tp/VVVUnSVVV_^GVVVVt%7fVVVVSvTSocu%E&uPB<VFVVV_ZFVVVVTUFRVFFTTVRZVpxTTVR\Vp**'
xor_key = int(input('Plz input key (0<key<100):'))
# 计算积分值
integral_value = (xor_key ** 2) / 2 + xor_key + 2/3
check_value = 13024
if integral_value * 3 == check_value:
# 异或解密
xor_decoded_data = bytes([byte ^ xor_key for byte in encoded_data])
# base64解码
decoded_data = base64.b64decode(xor_decoded_data)
# 反序列化为可执行代码对象
code_obj = marshal.loads(decoded_data)
# 执行代码
exec(code_obj)
else:
print('Wrong!!')
```
输入密钥后,程序将计算出积分值,并与给定的检查值进行比较,如果相等,则进行解密操作,并最终执行解密后的代码对象。
