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]);
}
