                PHP dan GPG
              
          
    Pengenalan

Terdapat 2 pihak iaitu pihak A dan pihak B. Pihak A ingin menghantar encrypted data pada pihak B dan pada masa yang sama pihak B juga ingin menghantar encrypted data pada pihak A. Bagi menyelesaikan masalah ini kita boleh menggunakan asymmetric cryptography seperti library GnuPG (GPG).
Di dalam asymmetric cryptography, pihak A dan pihak B perlu mempunyai sepasang kekunci yang dipanggil sebagai Public Key dan Private Key. Public Key dan Private Key ini mempunyai tujuan masing-masing:

Public Key digunakan untuk encrypt data. Jadi, Public Key boleh diberikan kepada siapa-siapa yang diinginkan.
Private Key digunakan untuk decrypt data. Jadi, Private Key perlu disimpan dengan selamat dan tidak boleh diberikan kepada sesiapa.


Untuk pengetahuan anda, Private Key dan Secret Key adalah sama.
