Replaces LocalSecurityEncryptAES128ECB.

​
Function Syntax

long SecurityLocalEncryptAES128ECB(byte key[], dword keyLength, byte data[], dword dataLength, byte cipheredData[], dword cipheredDataLength)

​
Description

Encrypts data with a given key using AES128 (ECB), Padding Mode PKCS5.

​
Parameters

  • byte key[]
    The key to be used for AES (128 bit).
  • dword keyLength
    16 (bytes).
  • byte data[]
    The data to encrypt.
  • dword dataLength
    The length of the data to encrypt.
  • byte cipheredData [] [Out]
    The buffer in which the ciphered data is stored.
  • dword cipheredData Length [In/Out]
    The length of the buffer. Typically this buffer has to be 16 bytes longer than the length of the data to encrypt.

​
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

void Encrypt1(byte E1[])
{
  byte BaseKey[16] = {0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};
  byte Data[16] = {0x01,0x23,0x45,0x67,0x89,0xAB,0xCD,0xEF,0x01,0x23,0x45,0x67,0x89,0xAB,0xCD,0xEF};
  byte Result[32];
  dword length = elCount(Result);
  int i;
  dword res;

  res = SecurityLocalEncryptAES128ECB(BaseKey, elCount(BaseKey), Data, elCount(Data), Result, length);

  write("SecurityLocalEncryptAES128ECB Result: %d", res);
  for(i = 0; i < length; i++) write("Result Byte %d : %x", i, Result[i]);
}
