​
Note

Replaces LocalSecurityGenerateSHA512.

​
Function Syntax

long SecurityLocalGenerateSHA512(byte data[], dword dataLength, byte sha512[], dword sha512Length)

​
Description

Generates a SHA512 hash for the given data and using the given key.

​
Parameters

  • byte data[]: The data to encrypt.
  • dword dataLength: The length of the data to encrypt.
  • byte sha512[] [Out]: The generated SHA512 hash.
  • dword sha512Length [In/Out]: The length of the generated SHA512 hash (64 bytes).

​
Return Values

  • 1: Success. A value of 1 means that the action was successful.
  • <= 0: Error. A value less than or equal to 0 means error.

​
Example

byte data[3] = { 0x61, 0x62, 0x63 };
byte refOutput[64] ={
  0xdd, 0xaf, 0x35, 0xa1, 0x93, 0x61, 0x7a, 0xba,
  0xcc, 0x41, 0x73, 0x49, 0xae, 0x20, 0x41, 0x31,
  0x12, 0xe6, 0xfa, 0x4e, 0x89, 0xa9, 0x7e, 0xa2,

};

dword refOutputLength = 64;
byte output[64];
dword outputLength = 64;
dword result = 255;
dword counter = 0;
result = SecurityLocalGenerateSHA512(data, elCount(data), output, outputLength);
