Apple Submit for review : encryption features

[soriyanykeo]

Hello there,
I planed to submit my app for review but there is a question about encryption features. I am not sure I should answer Yes/No. In the app i am using crc32 and password. Should i need to get a properly authorized encryption features to submit first?

sample code:
NSString _fileName = [strTokenString lastObject];
NSData *dataObj = [NSData dataWithContentsOfFile:str];
NSString *fileNameString = [NSString stringWithFormat:@"%@", fileName];
unsigned long result = crc32(0, dataObj.bytes, (unsigned int)dataObj.length);
ZipWriteStream_stream = [zipefile writeFileInZipWithName:fileNameString fileDate:[NSDate date] compressionLevel:ZipCompressionLevelDefault password:@"EtoxpxizuAYK3MV7XcyTC" crc32:result];
[stream writeData:dataObj];
[stream finishedWriting];

Thanks-
