[파이썬] 전체 바이너리에서 gzip 파일 찾아서 압축 해제하기

import sys, os, gzip filename=sys.argv[1] or_fd=open(filename,'rb') ch_filename = "change_"+filename+".gz" for i in range(0xb,os.path.getsize(filename)): # gzip Header Size = 0xa or_fd.seek(0) wr_fd = open(ch_filename,"wb") wr_fd.write(or_fd.read(i+0x8)) # gzip Footer Size = 0x8 wr_fd.close() with gzip.open(ch_filename, "rb") as f: #gzip Decompress -------- op=open("test_out.bin","wb") try: op.write(f.read()) # gzip Decompress ------------ op.close() print "SUCCESS!!!!" break except: # if ch_filename is not gzip... print str(i)+"/"+str(os.path.getsize(filename))+" ("+'{percent:.2%}'.format(percent=float(i)/float(os.path.getsize(filename)))+") : except" op.close() pass or_fd.close()

성공한다면, 

test_out.bin 이 압축 해제된 파일이다.
