Updating the Password Encryption Algorithm

Updating the Password Encryption Algorithm

Data Archive user passwords and source and target connection passwords are encrypted and stored in the AMHOME tables. The passwords are encrypted with the RC4 algorithm.
You can change the algorithm used to encrypt the passwords to the AES256 algorithm. The AES256 algorithm adds an additional layer of encryption with the master key. By default, the master key is stored in a key.file in the Data Archive installation directory. You can change the name and location of the file if required.
You need the master key to decrypt and access the host key which provides access to the passwords. You cannot decrypt the passwords if you lose or edit the master key. Take a backup of the file and store the file in a secure location.
Use the AESEncryptionUtility to encrypt passwords with the AES256 algorithm and to update password encryption when required.
After each successful run of the encryption utility, users must download Enterprise Data Manager.
