About Hongkong Post e-Cert

Hongkong Post e-Cert - The Solution to Online Trading

We have all witnessed the explosion of Internet services and how they have integrated into our daily lives. People are now used to sending e-mail, exchanging electronic data and conducting commercial transactions over the Internet or other electronic means regularly.

Like a lot of us however, you probably still wonder how secure your online transactions are. Concerns arise as to whether:

  • a person is really who he/she claims to be;
  • your e-mail content has been tampered with; and
  • the privacy of your electronic communications with others can be protected.

That is why Hongkong Post built a Public Key Infrastructure ("PKI") in early 2000 and became the first public recognized certification authority ("CA") under the Electronic Transactions Ordinance ("ETO") (Cap. 553). As a recognized CA, Hongkong Post CA issues recognized digital certificates ("e-Cert") that comply with the provisions of the ETO. Under the ETO, digital signature supported by an e-Cert has the same legal status as a handwritten signature. Hongkong Post e-Cert is issued to individuals and businesses to authenticate the online identity of subscribers and to facilitate the conduct of online transactions in a secure and trusted environment. Hongkong Post CA also maintains a certificate repository and directory to allow the public to verify the validity of a particular Hongkong Post e-Cert.
