Encrypting Custom Fields
Encryption for Jira allows you to create three types of custom fields specifically for encryption: a single-line and multi-line encrypted text field and an encrypted password field. Once you have created these fields, you can set the permissions using the visibility restrictions in Encryption for Jira.
Create New Custom Fields for Encryption
Creating a new custom field for encryption purposes is performed like any other custom field in Jira. These custom fields are text and password-type fields, and you can find them in the Jira Administration menu under Issues.
Once created, the text field's value is encrypted within the Jira database.
Filtering Encrypted Custom Fields
By default, encrypted custom fields have the Encrypted Custom Field Searcher template.
Users can search for texts as they do with Jira's native text custom fields.
To make a change, click the Three-dot menu next to the desired custom encrypted field, then select Edit details.
Make your desired changes on the Edit Custom Field Details screen, then click Update.
Basic filter
Advanced filter
To be able to index the fields, Lucene stores the decrypted values. Therefore, a user with access to the file system could access the Lucene indexes and see the values of the fields. If this is a problem, you can unlink the field from the searcher by selecting None from the Search Template dropdown menu in the Edit Custom Field Details screen. This way, Lucene will not store any decrypted value, and no user can search by this custom field in a filter.
