Decode Base64 fields
editDecode Base64 fields
editThe decode_base64_field
processor specifies a field to base64 decode.
The field
key contains a from: old-key
and a to: new-key
pair. from
is
the origin and to
the target name of the field.
To overwrite fields either first rename the target field or use the drop_fields
processor to drop the field and then rename the field.
processors: - decode_base64_field: field: from: "field1" to: "field2" ignore_missing: false fail_on_error: true
In the example above: - field1 is decoded in field2
The decode_base64_field
processor has the following configuration settings:
-
ignore_missing
-
(Optional) If set to true, no error is logged in case a key
which should be base64 decoded is missing. Default is
false
. -
fail_on_error
-
(Optional) If set to true, in case of an error the base64 decode
of fields is stopped and the original event is returned. If set to false, decoding
continues also if an error happened during decoding. Default is
true
.
