Additional authentication data (AAD) used in GCM mode.
Data Type
StringDefault Value
""Remarks
This setting optionally specifies additional authentication data. The data specified must be hex encoded. This is only applicable when CipherMode is set to 6 (cmGCM). This may be set prior to encryption or decryption.
Note that AAD data is authenticated but not encrypted, so it is not included in the output message.
