Encrypting Storage Tables for Substitution Masking
Encrypting Storage Tables for Substitution Masking
You can use transformation language encoding functions to encrypt storage tables. You need to encrypt storage tables when you have enabled storage encryption.
Create a mapping with the IDM_SUBSTITUTION_STORAGE storage table as source.
Create a Data Masking transformation.
Apply the substitution masking technique on the input value and the masked value ports.
Use the following expression on the INPUTVALUE port:
Enc_Base64(AES_Encrypt(INPUTVALUE, Key))
Use the following expression on the MASKEDVALUE port:
