为目标C中的字符串生成sha256哈希,相当于C#,而不使用键
在c#中,我正在做为目标C中的字符串生成sha256哈希,相当于C#,而不使用键,c#,objective-c,hash,sha256,C#,Objective C,Hash,Sha256,在c#中,我正在做 HashAlgorithm hash=SHA256.create(); string myHash = Convert.ToBase64String( hasher.ComputeHash(Encoding.UTF8.GetBytes("hello"))); const unsigned char arr[32]; CC_SHA256([@"hello" UTF8String], 32, &arr); NSMutableDa
HashAlgorithm hash=SHA256.create();
string myHash = Convert.ToBase64String( hasher.ComputeHash(Encoding.UTF8.GetBytes("hello")));
const unsigned char arr[32];
CC_SHA256([@"hello" UTF8String], 32, &arr);
NSMutableData *HM = [NSData dataWithBytes:(const void *)arr length:32];
NSLog(@"macHah %@",[HM base64EncodingWithLineLength:0]);
在目标c中,我正在做
HashAlgorithm hash=SHA256.create();
string myHash = Convert.ToBase64String( hasher.ComputeHash(Encoding.UTF8.GetBytes("hello")));
const unsigned char arr[32];
CC_SHA256([@"hello" UTF8String], 32, &arr);
NSMutableData *HM = [NSData dataWithBytes:(const void *)arr length:32];
NSLog(@"macHah %@",[HM base64EncodingWithLineLength:0]);
但这两种方法都会生成不同的散列请尝试使用以下方法:
- (NSData *)sha256:(NSData *)data
{
unsigned char hash[CC_SHA256_DIGEST_LENGTH];
if ( CC_SHA256([data bytes], [data length], hash) )
{
NSData *hashData = [NSData dataWithBytes:hash length:CC_SHA256_DIGEST_LENGTH];
return hashData;
}
return nil;
}
尝试使用以下方法:
- (NSData *)sha256:(NSData *)data
{
unsigned char hash[CC_SHA256_DIGEST_LENGTH];
if ( CC_SHA256([data bytes], [data length], hash) )
{
NSData *hashData = [NSData dataWithBytes:hash length:CC_SHA256_DIGEST_LENGTH];
return hashData;
}
return nil;
}
