End Header: it contains link to Compressed Metadata Block. Note: If 7z archive contains only one file without encryption, 7-Zip stores Metadata for that file in End Header in uncompressed form, and there 7 zip data error the archive is corrupted are only 3 main blocks in that case. Archive example Archive example: a.7z (3740 bytes) that contains 5 files compressed with LZMA method.

I can create them and open them fine when building as a 64 bit Mac app. However when trying to open them in the 32 bit iOS simulator I have problems. data error The zip opens fine, but the password-protected file cannot be extracted and it gives an error: Error reading ‘file’ in the zipfile The zip that is created on the 64 bit Mac app also has the same problems when attempting to be opened by 7-zip on Windows: Data error in encrypted file ‘file’. Wrong password? There are no problems if I don’t password-protect the zip and in this case they can be passed zip data error between 64 bit and 32 bit iOS and Mac systems and also Windows. Although, curiously, I cannot double-click and extract the zips in the Finder - I get a .cpgz file created instead. There were many compiler warnings about loss of precision from longs to ints when using XCode 5.1. I can silence the compiler with casts in the code, but the issues above remain whether I add the casts or leave the code as it is. I am using XCode 5.1 on OS X 10.9.2 and version 0.8.3 of Objective-Zip. Hope you can help Thanks bcyng commented Sep 20, 2014 i get the same problem. if i encrypt a file on a 32 bit device and open on a 64bit device it fails or vice versa. RyouZhang commented Sep 29, 2014 when change the code in crypt.h, the problem fixed #define CRC32(c, b) ((*(get_crc_table()+(((int)(c) ^ (b)) & 0xff))) ^ ((c) >> 8)) Sign up for free to join this conversation on GitHub.
