Jul 14, 2017 · I've written some Word VBA programs (Word 2016) and signed them with my Digital Certificate (issued by DigiCert, valid until 2020). They work fine on other machines with Word 2016. However, when I try them on machines with Office-365 (MS-Office 2016), they don't run as macros are disabled.

In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates.A digital certificate certifies the ownership of a public key by the named subject of the certificate. Jan 03, 2017 · A digital certificate binds a public key with an identity and plays an essential role in securing communications over the internet and other networks. This enables a user or device to verify with How does a Wildcard certificate work? Our DigiCert Wildcard SSL Certificate provides SSL protection for unlimited first-level sub-domains of the domain name you specify in your Certificate Signing Request (CSR). For example, you get a DigiCert SSL Wildcard Certificate for *.your_domain.com. With this certificate, you can secure unlimited first The digital certificate ranges between $90 and $119 bepending on the vendor you choose to use. There are several methods of payment which depend on the vendor you choose to work with. The payment method is spelled out on each vendors website. The application process takes approximately 2 weeks. How SSL Certificates Work. A browser or server attempts to connect to a website (i.e. a web server) secured with SSL. The browser/server requests that the web server identify itself. The web server sends the browser/server a copy of its SSL certificate. The browser/server checks to see whether or not it trusts the SSL certificate. the certificate is signed, and that signature itself is enough proof that the certificate is valid because the client can make sure, by his own, and without contacting the issuer's server, that that certificate is authentic. A digital certificate binds a user, computer, or service’s identity to a public key by providing information about the subject of the certificate, the validity of the certificate, and applications and services that can use the certificate.

It is hard to explain the role of digital certificates if you don't understand public key cryptography and the concept of a signing authority. So allow a short analogy: A digital certificate is an electronic document that says you are who you sa These solutions include certificate signatures that let you sign PDF files with a certificate-based digital ID. Certificate signatures are also known as digital signatures. Acrobat lets you create your own certificate ID. However, the more common approach is to work with a certificate ID that a trusted third-party certificate authority issued.
