Dear Serhiy, in the case of correct password, the program works well:

OACD PACD QACD RACD SACD TACD UACD VACD WACD XACD YACD ZACD ABCD Password found:ABCD

for five characters:

RRJBA Traceback (most recent call last): File "p33.py", line 54, in zf.extractall( pwd=password.encode('cp850','replace')) File "/usr/lib/python3.5/zipfile.py", line 1347, in extractall self.extract(zipinfo, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1335, in extract return self._extract_member(member, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1399, in _extract_member shutil.copyfileobj(source, target) File "/usr/lib/python3.5/shutil.py", line 73, in copyfileobj buf = fsrc.read(length) File "/usr/lib/python3.5/zipfile.py", line 844, in read data = self._read1(n) File "/usr/lib/python3.5/zipfile.py", line 934, in _read1 self._update_crc(data) File "/usr/lib/python3.5/zipfile.py", line 862, in _update_crc raise BadZipFile("Bad CRC-32 for file %r" % self.name) zipfile.BadZipFile: Bad CRC-32 for file '11_02_2019.pdf'

specially for RRJBA AAAAA Traceback (most recent call last): File "p33.py", line 54, in zf.extractall( pwd=password.encode('cp850','replace')) File "/usr/lib/python3.5/zipfile.py", line 1347, in extractall self.extract(zipinfo, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1335, in extract return self._extract_member(member, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1399, in _extract_member shutil.copyfileobj(source, target) File "/usr/lib/python3.5/shutil.py", line 73, in copyfileobj buf = fsrc.read(length) File "/usr/lib/python3.5/zipfile.py", line 844, in read data = self._read1(n) File "/usr/lib/python3.5/zipfile.py", line 934, in _read1 self._update_crc(data) File "/usr/lib/python3.5/zipfile.py", line 862, in _update_crc raise BadZipFile("Bad CRC-32 for file %r" % self.name) zipfile.BadZipFile: Bad CRC-32 for file '11_02_2019.pdf'

for six characters:

KMQAAA LMQAAA MMQAAA NMQAAA OMQAAA PMQAAA QMQAAA RMQAAA SMQAAA TMQAAA UMQAAA VMQAAA WMQAAA XMQAAA YMQAAA ZMQAAA ANQAAA Traceback (most recent call last): File "p33.py", line 54, in zf.extractall( pwd=password.encode('cp850','replace')) File "/usr/lib/python3.5/zipfile.py", line 1347, in extractall self.extract(zipinfo, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1335, in extract return self._extract_member(member, path, pwd) File "/usr/lib/python3.5/zipfile.py", line 1399, in _extract_member shutil.copyfileobj(source, target) File "/usr/lib/python3.5/shutil.py", line 73, in copyfileobj buf = fsrc.read(length) File "/usr/lib/python3.5/zipfile.py", line 844, in read data = self._read1(n) File "/usr/lib/python3.5/zipfile.py", line 934, in _read1 self._update_crc(data) File "/usr/lib/python3.5/zipfile.py", line 862, in _update_crc raise BadZipFile("Bad CRC-32 for file %r" % self.name) zipfile.BadZipFile: Bad CRC-32 for file '11_02_2019.pdf'

It seems that after certain attempts command produces different behaviour as in the previous attemts to call zf.extractall( pwd=password.encode('cp850','replace'))

Best regards

Jozef

Do you get an error when try to extract the file using the valid password?
