Indonesia is the 4th most populous country in the world with around 277 million people and tens of millions if not hundreds of millions of them have active secure personal document signing certificates.

Indonesian law separates electronic signature into 2 groups: a) Uncertified and b) Certified

Law text is available online at

Uncertified electronic signatures have low value and can be almost anything. They can be verified only in court with additional evidence and some use cases, which you might not know, are not permitted at all.

Exact wording about electronic signature in the law is “22. Electronic Signature means a signatures comprising Electronic Information attached to, associated with, or related to other Electronic Information, which is used as a verification and authentication tool” and in original Indonesian “Tanda Tangan Elektronik adalah tanda tangan yang terdiri atas Informasi Elektronik yang dilekatkan, terasosiasi atau terkait dengan Informasi Elektronik lainnya yang digunakan sebagai alat verifikasi dan autentikasi.”

Certified electronic signatures are created PKI X509 by certificates issued using Certificate Authorities approved by Penyelenggara Sertifikasi Elektronik (PSrE). 

Certified electronic signatures can easily be verified if you upload the document into this government validator . Since there are standard procedures and validation then it is much safer than any nonstandard uncertified signature.

Currently there are 9 certified CA-s as can be seen from
