我正在尝试从.net函数编写用于在目标中创建sha512字符串的函数,该函数是
public static string GetSHA512(string strPlain)
{
UnicodeEncoding UE = new UnicodeEncoding();
byte[] HashValue = null;
byte[] MessageBytes = UE.GetBytes(strPlain);
System.Security.Cryptography.SHA512Managed SHhash = new System.Security.Cryptography.SHA512Managed();
string strHex = string.Empty;
HashValue = SHhash.ComputeHash(MessageBytes);
foreach (byte b in HashValue)
{
strHex += String.Format("{0:x2}", b);
}
return strHex;
}
这给出了结果
input : pass123
output: 2a6353744cc2914c602265f50d2e413d0561368775756392517abb340ef75d52ee0c5d3623ddd1826fd768a13dca8961f5957c75df0d793b9d7537aabe050705
我尝试过的如下
-(NSString *)createSHA512:(NSString *)string
{
const char *cstr = [string cStringUsingEncoding:NSUTF8StringEncoding];
NSData *data = [NSData dataWithBytes:cstr length:string.length];
uint8_t digest[CC_SHA512_DIGEST_LENGTH];
CC_SHA512(data.bytes, data.length, digest);
NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA512_DIGEST_LENGTH];
for(int i = 0; i < CC_SHA512_DIGEST_LENGTH; i++)
[output appendFormat:@"%02x", digest[i]];
return output;
}
结果如下
input : pass123
output: fd37ca5ca8763ae077a5e9740212319591603c42a08a60dcc91d12e7e457b024f6bdfdc10cdc1383e1602ff2092b4bc1bb8cac9306a9965eb352435f5dfe8bb0
谁能建议我做错了什么?
为什么这两个值不同?
请纠正我的错误。
编辑
意思是虽然我尝试将编码更改为NSUTF16StringEncoding
,NSUnicodeStringEncoding
但结果仍然不同,如下所示
input : pass123
output: 514331e3f7ca0a295539347ebccc4e4f095fe5f3c1df10d43b4d550144c7b30ba9507831893ea63ea22e62e993be529b0d14be7800a90aa0de199d6be62a5f1b
