Hi, I am trying to encode data from flatfile and then to decode the encoded data to original form. Procedures that I followed:- 1. Encoded the field 'A_ID' using AES_ENCRYPT(A_ID,'abd') in the expression transformation. The A_ID got encoded in the output table(oracle) 2. To decode this back I used AES_DECRYPT(A_ID,'abd'). But after executing the workflow, I am not getting any data in output. can anybody tell me how to decrypt the encoded data back to original form ??
