To strengthen security encryption, the Informatica installer now generates a unique site key when you install the Informatica services. You cannot generate the site key again. Previously you could regenerate the encryption site key using a keyword and domain name in the

GenerateEncryptionKey

command.

After you upgrade to Informatica 10.5, migrate the site key to the new unique site key.

For a multinode domain, copy the unique site key to each node or save the unique site key at a shared location that can be accessed by each node.

You can use transformation language encoding functions,

AES_ENCRYPT

and

AES_DECRYPT

to encrypt or decrypt storage tables with 256-bit encoding. Use the new argument,

keySize

to enable AES 256-bit encryption.
