Azure Key Vault Import Certificate
See more Azure Key Vault Examples
Imports a certificate into a specified Azure key vault.Imports an existing valid certificate, containing a private key, into Azure Key Vault. The certificate to be imported can be in either PFX or PEM format. If the certificate is in PEM format the PEM file must contain the key as well as x509 certificates. Key Vault will only accept a key in PKCS#8 format.
