## Member Function Documentation

## ◆ Initialize()

CertificateSecurityHandler.Initialize | ( | encrypt_data | ,
|  | encrypt_key |
| ) |  |

Initialize current certificate security handler.

Parameters

  [in] | encrypt_data | A certificate encrypt data object. In the encryption data, cipher type should not be SecurityHandler.e_CipherNone.
  [in] | encrypt_key | The key for encryption. For SecurityHandler.e_CipherRC4 cipher, the length of encryption key should be between 5 and 16. For SecurityHandler.e_CipherAES cipher, the length of encryption key should be 16 or 32.

Returns
  true means success, while false means failure.
