The PKI file extension is associated with Entrust public key infrastructure software. These files are used by applications that manage certificates and perform related operational or ancillary PKI tasks.
A PKI file can contain PKI messages exchanged through certificate management protocols defined by the IETF PKIX Working Group. Entrust applications can use these messages with e-mail or HTTP transport, including protected or encrypted security data.
MIME type:
application/pkixcmp
Open or import a PKI file with the Entrust PKI application or security product that created it. The file is normally processed as part of an Entrust certificate-management or PKI communication workflow, not opened in a text editor.
If the file does not open, the required Entrust software or access to the corresponding PKI system may be missing. Do not edit the file manually, because this can invalidate its security data.
A PKI file is a protocol or security message, not a document format that can usually be converted directly. Keep it in its original form when it is needed for an Entrust PKI workflow.
