The PowerBuilder 11.5.1 development environment meets the encryption requirements of the Federal Information Processing Standard (FIPS) as outlined in Publication 140-2 of the United States government's National Institute of Standards and Technology. To meet these standards, PowerBuilder embeds the Certicom 5.x cryptographic modules. Support is certified for the PowerBuilder development environment only, not for runtime applications that are built with PowerBuilder. The FIPS 140-2 standard requires that passwords be encrypted. The PowerBuilder 11.5.1 user interface displays all passwords as strings of asterisks. Some files with passwords, such as database profiles, that you export from PowerBuilder 11.5.1, cannot be correctly imported into earlier versions of PowerBuilder because of the enhanced password protection. However you can still import files containing unencrypted passwords from earlier versions of PowerBuilder. When you save these files in or export them from PowerBuilder 11.5.1, the passwords are encrypted using a FIPS compatible method.
