+The `--hide` flag can be used multiple times to hide sensitive data.  
+As these obfuscators are based on regex, you must add a regex pattern that meets your requirements.
 
-`# support-collector --hide "Secret:.*" --hide "Password:.*"`

+This will replace:

 In addition, files and folders that follow a specific pattern are not collected. This affects all files that correspond to the following filters:  
 `.*`, `*~`, `*.key`, `*.csr`, `*.crt`, and `*.pem`
