Decrypts data using a key.
Object Oriented Interface
public function doDecrypt($keyname, $versionid);
Procedural Interface
cloudkeys_googlekms_do_decrypt($res, $keyname, $versionid);
Remarks
This method decrypts data using the key specified by KeyName and (for asymmetric keys) VersionId.
The data to decrypt is taken from the the specified InputFile or the InputData property. The decrypted data is output to the the specified OutputFile or the OutputData property.
For symmetric keys, VersionId must be empty; the server automatically detects which version of the symmetric key to use for decryption.
For asymmetric keys, VersionId must be specified.
