This feature is new in the Solaris 9 12/02 release.
Password encryption protects passwords from being read by intruders. Three strong password encryption modules are now available in the software:
A version of Blowfish that is compatible with Berkeley Software Distribution (BSD) systems
A version of Message Digest 5 (MD5) that is compatible with BSD and Linux systems
A stronger version of MD5 that is compatible with other Solaris systems
For information on how to protect your user passwords with these new encryption modules, see the System Administration Guide: Security Services. For information on the strength of the modules, see the crypt_bsdbf(5), crypt_bsdmd5(5), and crypt_sunmd5(5) man pages.
