iOS & Java (Android、Java Web...) encryption-decryption(AES,RSA,MD5) and coder-decoder(Base64).
code for iOS安全之路
##Usage
###MD5
NSString* testSalt = @"1234567890";
NSString* testString = @"123456";
NSLog(@"testString:%@",testString);
NSData* testData = [testString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"testData:%@",testData);
NSString* md5String = [CATSecurity md5StringWithData:testData];
NSLog(@"md5StringWithData:%@",md5String);
NSData* data = [CATSecurity md5DataWithData:testData];
NSLog(@"md5DataWithData:%@",data);
md5String = [CATSecurity md5StringWithString:testString];
NSLog(@"md5StringWithString:%@",md5String);
md5String = [CATSecurity md5StringWithString:testString salt:testSalt];
NSLog(@"md5StringWithString:salt: :%@",md5String);
md5String = [CATSecurity md5StringMultipleWithString:testString];
NSLog(@"md5StringMultipleWithString:%@",md5String);
md5String = [CATSecurity md5StringDisorderWithString:testString];
NSLog(@"md5StringDisorderWithString:%@",md5String);
###Base64
NSString* testString = @"123456";
NSLog(@"testString:%@",testString);
NSData* testData = [testString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"testData:%@",testData);
NSString* base64EncodedString = [CATSecurity base64EncodedStringWithData:testData];
NSLog(@"base64EncodedStringWithData:%@",base64EncodedString);
NSData* data = [CATSecurity dataWithBase64EncodedString:base64EncodedString];
NSLog(@"dataWithBase64EncodedString:%@",data);
base64EncodedString = [CATSecurity base64EncodedStringWithString:testString];
NSLog(@"base64EncodedStringWithString:%@",base64EncodedString);
NSString* str = [CATSecurity stringWithBase64EncodedString:base64EncodedString];
NSLog(@"stringWithBase64EncodedString:%@",str);
###AES
NSString* testKey = @"key1233215678987";
NSString* testString = @"123456";
NSLog(@"testString:%@",testString);
NSData* testData = [testString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"testData:%@",testData);
NSData* data = [CATSecurity aes256EncryptWithData:testData key:testKey];
NSLog(@"aes256EncryptWithData:key:%@",data);
//将加密好的data base64编码后传给java
NSString* base64EncodedString = [CATSecurity base64EncodedStringWithData:data];
NSLog(@"base64EncodedStringWithData:%@",base64EncodedString);
data = [CATSecurity aes256DecryptWithData:data key:testKey];
