Memilih Serifikat SSL

Kalau berkunjung ke situs-situs yang menjual serifikat SSL, akan dibuat bingung, mana SSL yang harus dibeli. Sebelum membeli SSL, coba cek SSL yangs udah dipakai selama ini. Misal untuk server siren, simonev, insentif, surat, dan webmail. Rata-rata menggunakan GeoTrust DV SSL CA. Ada juga yang pakai RapidSSL CA. Ada 3 macam GeoTrust DV SSL CA, yaitu GeoTrust DV SSL CA dan GeoTrust DV SSL CA - G3, dan GeoTrust DV SSL CA - G4. Saya sendiri tidak tahu persis perbedaaannya. Apakah ada hubungan dengan tahun release-nya.
