1.引入CJMD5三方库
#import <CommonCrypto/CommonDigest.h>
3.32位的加密方法
- (NSString *)getMd5_32Bit_String:(NSString *)srcString{
const char *cStr = [srcString UTF8String];
unsigned char digest[CC_MD5_DIGEST_LENGTH];
CC_MD5( cStr, strlen(cStr), digest );
NSMutableString *result = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)
[result appendFormat:@"%02x", digest[i]];
return result;
}
NSString *md5 = [self getMd5_32Bit_String:_keyTextField.text];
