Base64 Decode

Introduction

This valve decodes item properties encoded in base 64. The decoded value can replace the source value or replace/create a new named property.

Note that items only support string properties. This means that the binary result of the decode operation is used to create a string that can be added to an item. Real binary data (like PDF documents or images) must be externally encoded/decoded when using it with items.

Note

This valve is a part of the item iteration API meaning that it operates on the current item set. For more information on item iteration, see Item.

Configuration

Note

Valve name: Base64Decode

Caution

The properties of this valve has changed to better reflect how the valve actually works.

value (previously called src) must be an expression expanding to the value to encode (or a static value).

name (previously called dest) must be the name of the property to set with the resulting base64 value.

Properties

Name	Description	Default	Mandatory	Expanded

value	Name of the item property containing base 64 encoded data to decode. (compat: src)

  "name" : "Base64Decode",
