Hello I am building a simple file encryption software and I am facing
issues with files larger than 200KB not being fully uploaded but resulting
in success. I am running nginx server / web2py. However I am pretty sure
it's configuration is set up correctly
Perhaps some one could take a look at my code and offer some advice.
upload_file controller
if form.process(onvalidation=encryptUpload).accepted:
session.file_id = form.vars.id
return XML('ajax("%s",[],"status");' % URL('default',
'encrypt_file.load'))
encryptUpload - OnValidation
def encryptUpload(form):
#validator.validate(form.vars.file_upload.file)
# on success set hidden fields
#tmppath = os.path.join(request.folder, 'uploads', 'tmpupf%f.temp.w2p'
% random.random())
filename = form.vars.file_upload.file
#filepath = open(tmppath, 'wb')
#shutil.copyfileobj(filename, filepath)
#filepath.close()
#in_filename = str(tmppath)
outfile = cStringIO.StringIO()
iv = ''.join(random.choice('0123456789ABCDEF') for i in range(16))
key =
''.join(random.choice('0123456789!@#$%^&*()ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstufwxyz')
for i in range(32))
aes = AES.new(key, AES.MODE_CBC, iv)
chunksize = 64 * 1024
filename.seek(0, os.SEEK_END)
filesize = filename.tell() #os.path.getsize(str(tmppath))
filename.seek(0)
#with open(in_filename, 'rb') as infile:
outfile.write(struct.pack('<Q', filesize))
outfile.write(iv)
while True:
chunk = filename.read(chunksize)
if len(chunk) == 0:
break
elif len(chunk) % 16 != 0:
chunk += " " * (16 - len(chunk) % 16)
outfile.write(aes.encrypt(chunk))
outfile.seek(0)
form.vars.file_upload.file = outfile
#os.system("srm %s" % tmppath)
#os.rename(out_filename, filename)
session.key = key
Any advice is appreciated.
*cheers
