如何将加密数据转换为字符串
我已经使用 任何用于 AES 加密的可可源代码中发布的代码对 NSData 进行了加密解密?(由 Rob Keniger 回答)。现在我需要检查加密是否正确。为此,我使用代码将加密的 NSData 转换为 NSString,
NSString *string=[[NSString alloc]initWithBytes:[cipherData bytes] length:[cipherData length] encoding:NSUTF8StringEncoding];
但是当 NSLog 编辑时,它显示 (null)。我的疑问是 crypt() 函数是否以不同的编码而不是 NSUTF8StringEncoding 加密数据?
I have encrypted NSData using the code posted in Any cocoa source code for AES encryption decryption? (Answered by Rob Keniger). Now I need to check the encryption is correct or not. For that I converted encrypted NSData to NSString, using the code
NSString *string=[[NSString alloc]initWithBytes:[cipherData bytes] length:[cipherData length] encoding:NSUTF8StringEncoding];
but when NSLog ed, it shows (null). My doubt is does the crypt() function encrypt data in different encoding rather than NSUTF8StringEncoding?

总的来说,NSData不能直接转NSString,我有个建议,你可以把这个NSData转Base64 NSString,如果你不想转回来,那就用Base64从NSString转NSData,找到一个“GTMBase64.h” ,这将帮助您

Overall,NSData can't directly transfer to NSString,I have a suggestion,you can make this NSData to Base64 NSString,and if you wan't to covert back,then use Base64 from NSString to NSData,find A "GTMBase64.h",that will help you
