List of decompressed attributes.
Parameters
Decompression Parameters
Attributes to Decompress
After connecting the transformer, click the browse button to select the attributes to Decompress.
Character Encoding for Decompressed Attributes
The decompression/decryption algorithms produce a string of bytes. Use this parameter to instruct the transformer how to interpret those bytes. If an encoded attribute was compressed in the AttributeCompressor transformer, this parameter should be set to the same encoding.
Decryption Parameters
Encryption Type
Use this parameter to select an encryption type. Currently, only the AES-256 encryption algorithm is supported.
Password
If encryption is being used, the value of this parameter will be used to generate an encryption key. This must be the same value used to encrypt the attribute values in the AttributeCompressor transformer.
Usage Notes
The AttributeDecompressor uses the zlib library to provide basic compression, and the OpenSSL library to provide encryption.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
