iOS加密之MD5加密

话不多说，上代码！

MyMD5.h里面

#import <Foundation/Foundation.h>

@interface MyMD5 : NSObject {

}

+(NSString *) md5: (NSString *) inPutText ;

@end

MyMD5.m里面

#import "MyMD5.h"
#import "CommonCrypto/CommonDigest.h"

@implementation MyMD5

+(NSString *) md5: (NSString *) inPutText
{
    const char *cStr = [inPutText UTF8String];
    unsigned char result[CC_MD5_DIGEST_LENGTH];

    CC_MD5(cStr, strlen(cStr), result);

    return [[NSString stringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",
             result[], result[], result[], result[],
             result[], result[], result[], result[],
             result[], result[], result[], result[],
             result[], result[], result[], result[]
             ] lowercaseString];
}

@end
