Public Shared Function OpenPublicKeyFromEngine (engineName As String, keyId As String) As SafeEvpPKeyHandle

Parameters

engineName: String

The name of the ENGINE to process the public key open request.

keyId: String

The name of the key to open.

Returns

SafeEvpPKeyHandle

The opened key.

Attributes: UnsupportedOSPlatformAttribute

Exceptions

ArgumentNullException

engineName or keyId is null.

ArgumentException

engineName or keyId is the empty string.

CryptographicException

the key could not be opened via the specified ENGINE.

Remarks

This operation will fail if OpenSSL cannot successfully load the named ENGINE, or if the named ENGINE cannot load the named key.

Not all ENGINEs support loading public keys, even ones that support loading private keys.

The syntax for keyId is determined by each individual ENGINE.
