how to parse unicode characters #4

Open carlesreig opened 3 years ago

carlesreig commented 3 years ago

When I try to encode this character "ú" (latin) it returns an error about encoding;

File "DahuaHash.py", line 45, in dhash m.update(passw.encode("ascii")) UnicodeEncodeError: 'ascii' codec can't encode character '\xfa' in position 0: ordinal not in range(128)

Is there some way to pass non ascii code to generate it's hash with this script?

You need to modify the script to accept the encoding used, so change

dhash m.update(passw.encode("ascii")) to

dhash m.update(passw.encode("iso-8859-1"))

It might work with utf-8, but i'm not sure how the multibyte encoding would affect the hashing algorithm. I assume that once it goes through the md5 hash, that it wouldn't affect anything else, but I haven't tested that. I have not made this a permanent change because it seems to be system specific.
