Get Text Certificate Extensions by OID

See more Certificates Examples

Demonstrates how to get text certificate extensions by OID. In this example, we have a certificate with the following OID extensions: 1.3.6.1.4.1.49952.5.8.5, 1.3.6.1.4.1.49952.5.8.6, 1.3.6.1.4.1.49952.5.8.7.

Most certificate extensions have values that are ASN.1 (binary). For the majority of cases, an application should call GetExtensionAsXml. For extensions known to have text values (such as the OIDs listed above), an application can instead call GetExtensionAsText.
