iOS 加密本地资源

直接上源码：

#import <Foundation/Foundation.h>
#import "DataEncryption.h"
/*
 思想：
 可以用归档输出需要加密的资源文件，要用资源文件时再进行解档。
 */

NSString * OutputFilePath(NSString *fileName) {
    NSString *outPutPath = [NSString stringWithFormat:@"/Users/#这里替换成你本机的用户名#/Desktop/Resource/%@%@",subPath,fileNam];
    return outPutPath;
}

NSString * InputFilePath(NSString *fileName) {
    //资源文件路径，其实就是那个 Resources 文件夹的路径
    return [NSString stringWithFormat:@"/Users/#这里替换成你本机的用户名#/Documents/ResourceEncryption/ResourceEncryption/Resource/%@", fileName];
}

/**归档二进制文件*/
void EncryptionDataFiles(NSArray *names) {
    [names enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSData *data = [NSData dataWithContentsOfFile:InputFilePath(obj)];
        [NSKeyedArchiver archiveRootObject:data toFile:OutputFilePath(obj)];
    }];
}

/**归档数组类型的Plist文件*/
void EncryptionArrayPlistFiles(NSArray *names) {
    [names enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        //原理同上
        NSArray *array = [NSArray arrayWithContentsOfFile:InputFilePath(obj)];
        [NSKeyedArchiver archiveRootObject:array toFile:OutputFilePath(obj)];
    }];
}

/**归档字典类型的Plist文件*/
void EncryptionDictionaryPlistFiles(NSArray *names) {
    [names enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        //原理同上
        NSDictionary *dic = [NSDictionary dictionaryWithContentsOfFile:InputFilePath(obj)];
        NSString *str = [DataEncryption convertToJsonData:dic];
        NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
        [NSKeyedArchiver archiveRootObject:data toFile:OutputFilePath(obj)];
    }];
}

int main(int argc, const char * argv[]) {
    @autoreleasepool {
       NSArray *names = @[@"aa.plist"];
       EncryptionDataFiles(names);
       EncryptionArrayPlistFiles(names);
       EncryptionDictionaryPlistFiles(names);
    }
    return 0;
}

PS:
解档的话，要保证需要解档的文件路径是完全没问题的，否则解不出来
