Regular Expressions¶

Regular expressions are one of the effective means to achieve data security. In Guance, you can apply them to scenarios such as snapshot sharing and sensitive data masking. Guance not only provides a built-in regular expression template library but also supports custom creation of regular expressions, which can be saved as rule libraries for easy future use.

Customization¶

Navigate to Manage > Regular Expressions > Custom, and click Create Regular Expression on the right side:

Enter the current rule name and the regular expression, then click Preview to view the masking effect in advance. The original text will be masked with *** based on the matching results from the regular expression on the left.

After entering the name and pressing Enter, a rule is created; clicking Confirm will finalize the creation of the current rule.

On the customization page, you can view all custom regular expressions. You can perform the following operations on the list:

1. Filter: Filter rules based on the rule library;
2. Search: Quickly search and locate rules by name;
3. Clone: Click to quickly duplicate the current rule;
4. Edit: Click to edit the current rule again;
5. Delete: Supports direct deletion or batch deletion.

Template Library¶

In Manage > Regular Expressions > Template Library, you can see all the built-in regular expression templates provided by the system. Click the clone button under the operations on the right to use them.
