Use a Created Key with AMPscript

Use AMPscript functions to encrypt and decrypt information stored in a custom data extension. The necessary AMPscript includes the EncryptSymmetric() and DecryptSymmetric() functions.

  1. Create the necessary keys.
  2. Create the information in the data extension you wish to encrypt.
  3. Include the AMPscript to perform the necessary encryption.
Example
Example

This example encrypts the plain text value ExampleData using provided values and then decrypts that variable. The @null variable represents an undeclared variable.

%%[
SET @encData=EncryptSymmetric("ExampleData", "AES", @null, "password", @null, "0000000000000000", @null, "00000000000000000000000000000000")
SET @clearData=DecryptSymmetric(@encData, "AES", @null, "password", @null, "0000000000000000", @null, "00000000000000000000000000000000")
]%%

This example accomplishes the same task using external keys instead of provided values.

%%[
SET @encData=EncryptSymmetric("ExampleData", "AES", "passwordExternalKey", @null, "saltExternalKey", @null, "IVExternalKey", @null)
SET @clearData=DecryptSymmetric(@encData, "AES", "passwordExternalKey", @null, "saltExternalKey", @null, "IVExternalKey", @null)
]%%
