Use the Character classes tab to specify which characters are permitted for a password.
Table 28: Character classes for passwords
|
Required number of character classes |
Number of rules for character classes that must be fulfilled so that a password adheres to the password policy. The following rules are taken into account for Min. number letters, Min. number lowercase, Min. number uppercase, Min. number digits, and Min. number special characters.
That means:
-
Value 0: All character class rules must be fulfilled.
-
Value >0: Minimum number of character class rules that must be fulfilled. At most, the value can be the number of rules with a value >0.
NOTE: Generated passwords are not tested for this. |

You can implement custom scripts for testing and generating passwords if the password requirements cannot be mapped with the existing settings options. Scripts are applied in addition to the other settings.
Detailed information about this topic
You can implement a script if additional policies need to be used for checking a password that cannot be mapped with the available settings.
Syntax of check scripts
Public Sub CCC_CustomPwdValidate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
With parameters:
policy = password policy object
spwd = password to check
TIP: To use a base object, take the Entity property of the PasswordPolicy class.
Example: Script that checks a password
A password cannot start with ? or ! . The password cannot start with three identical characters. The script checks a given password for validity.
Public Sub CCC_PwdValidate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
Dim pwd = spwd.ToInsecureArray()
If pwd.Length>0
If pwd(0)="?" Or pwd(0)="!"
Throw New Exception(#LD("Password can't start with '?' or '!'")#)
End If
End If
If pwd.Length>2
If pwd(0) = pwd(1) AndAlso pwd(1) = pwd(2)
Throw New Exception(#LD("Invalid character sequence in password")#)
End If
End If
End Sub
To use a custom script for checking a password
-
In the Designer, create your script in the Script Library category.
-
Edit the password policy.
-
In the Designer, select the Base data > Security settings > Password policies category.
-
In the List Editor, select the password policy.
-
On the Scripts tab, enter the name of the script to be used to check a password in the Check script field.
-
Save the changes.

You can implement a generating script if additional policies need to be used for generating a random password, which cannot be mapped with the available settings.
Syntax for generating script
Public Sub CCC_PwdGenerate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
With parameters:
policy = password policy object
spwd = generated password
TIP: To use a base object, take the Entity property of the PasswordPolicy class.
Example: Script that generates a password
In random passwords, this script replaces the invalid characters ? and ! at the beginning of a password with _.
Public Sub CCC_PwdGenerate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
Dim pwd = spwd.ToInsecureArray()
' replace invalid characters at first position
If pwd.Length>0
If pwd(0)="?" Or pwd(0)="!"
spwd.SetAt(0, CChar("_"))
End If
End If
End Sub
