Description:
Password strength checking for Kerberos KDCs
krb5-strength provides a password quality plugin for the MIT Kerberos KDC (specifically the kadmind server), an external password quality program for use with Heimdal, and a per-principal password history implementation for Heimdal. Passwords can be tested with CrackLib, checked against a CDB or SQLite database of known weak passwords with some transformations, checked for length, checked for non-printable or non-ASCII characters that may be difficult to enter reproducibly, required to contain particular character classes, or any combination of these tests. . No dictionary is shipped with this package. A CrackLib dictionary can be created with the tools in cracklib-runtime, a CDB or SQLite database can be created from a password list (obtained separately) using the tools included in this package, or both. . The recommended packages are needed to generate CDB or SQLite databases and for the password history implementation for Heimdal.
