[archive] Field level data encryption
[Migrated content. Thread originally posted on 23 March 2005]We need to encrypt data within a record. Our environment is AcuCobol 5.2.1 on an AIX box.
I believe we need an external utility / copybook that can be called to encrypt prior to writing and decrypt after read, depending upon a users security privleges. An unprivileged user would see garbled data, a person with the need to know the data would see the text. I am comfortable that we can keep the encryption key secure using the underlying OS security, but am unaware of a tool to perform the encryption/decryption.
Has anyone any experience with this?
