Character Set Password Validator
The Character Set Password Validator determines whether a proposed password is acceptable by checking whether it contains a sufficient number of characters from one or more user-defined character sets and ranges.
For example, the validator can ensure that passwords must have at least one lowercase letter, one uppercase letter, one digit, and one symbol.
Parent
The Character Set Password Validator object inherits from Password Validator.

allow-unclassified-characters
Synopsis |
Indicates whether this password validator allows passwords to contain characters outside of any of the user-defined character sets and ranges. |
Description |
If this is "false", then only those characters in the user-defined character sets and ranges may be used in passwords. Any password containing a character not included in any character set or range will be rejected. |

character-set
Synopsis |
Specifies a character set containing characters that a password may contain and a value indicating the minimum number of characters required from that set. |
Description |
Each value must be an integer (indicating the minimum required characters from the set which may be zero, indicating that the character set is optional) followed by a colon and the characters to include in that set (for example, "3:abcdefghijklmnopqrstuvwxyz" indicates that a user password must contain at least three characters from the set of lowercase ASCII letters). Multiple character sets can be defined in separate values, although no character can appear in more than one character set. |
Default value |
If no sets are specified, the validator only uses the defined character ranges. |
Allowed values |
A string. |

character-set-ranges
Synopsis |
Specifies a character range containing characters that a password may contain and a value indicating the minimum number of characters required from that range. |
Description |
Each value must be an integer (indicating the minimum required characters from the range which may be zero, indicating that the character range is optional) followed by a colon and one or more range specifications. A range specification is 3 characters: the first character allowed, a minus, and the last character allowed. For example, "3:A-Za-z0-9". The ranges in each value should not overlap, and the characters in each range specification should be ordered. |
Default value |
If no ranges are specified, the validator only uses the defined character sets. |
Allowed values |
A string. |

min-character-sets
Synopsis |
Specifies the minimum number of character sets and ranges that a password must contain. |
Description |
This property should only be used in conjunction with optional character sets and ranges (those requiring zero characters). Its value must include any mandatory character sets and ranges (those requiring greater than zero characters). This is useful in situations where a password must contain characters from mandatory character sets and ranges, and characters from at least N optional character sets and ranges. For example, it is quite common to require that a password contains at least one non-alphanumeric character as well as characters from two alphanumeric character sets (lower-case, upper-case, digits). In this case, this property should be set to 3. |
Default value |
The password must contain characters from each of the mandatory character sets and ranges and, if there are optional character sets and ranges, at least one character from one of the optional character sets and ranges. |
Allowed values |
An integer. Lower limit: 0. |
