在swift中使用md5by 伍雪穎


在ProjectName-Bridging-Header.h中添加#import<CommonCrypto/CommonCrypto.h>extension String {    var MD5:String {
        let cString =self.cStringUsingEncoding(NSUTF8StringEncoding)
        let length =CUnsignedInt(
            self.lengthOfBytesUsingEncoding(NSUTF8StringEncoding)
        )
        let result =UnsafeMutablePointer<CUnsignedChar>.alloc(Int(CC_MD5_DIGEST_LENGTH))
        CC_MD5(cString!,length,result)
        returnString(format:"%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x",
        result[0],result[1],result[2],result[3],result[4],result[5],result[6],result[7],result[8],
            result[9],result[10],result[11],result[12],result[13],result[14],result[15])
    }}

使用:

println("rain".MD5)
