Build the Template & Run

Prepare a template:

{
   "authorization":{
      "query":"[^\\w\\d\\n]+(?:basic|bearer)\\ .+",
      "ignorecase":true,
      "search":true
   },
   "variable":{
      "query":"(?:access|account|admin|basic|bearer|card|conf|cred|customer|email|history|id|info|jwt|key|kyc|log|otp|pass|pin|priv|refresh|salt|secret|seed|setting|sign|token|transaction|transfer|user)[\\w\\d]*(?:\\\"\\ *\\:|\\ *\\=).+",
      "ignorecase":true,
      "search":true
   },
   "comment":{
      "query":"[^\\w\\d\\n]+(?:bug|comment|fix|issue|note|problem|to(?:\\_|\\ |)do|work)[^\\w\\d\\n]+.+",
      "ignorecase":true,
      "search":true
   },
   "url":{
      "query":"\\w+\\:\\/\\/[\\w\\-\\.\\@\\:\\/\\?\\=\\%\\&\\#]+",
      "unique":true,
      "collect":true
   },
   "ip":{
      "query":"(?:\b25[0-5]|\b2[0-4][0-9]|\b[01]?[0-9][0-9]?)(?:\\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){3}",
      "unique":true,
      "collect":true
   },
   "base64":{
      "query":"(?:[a-zA-Z0-9\\+\\/]{4})*(?:[a-zA-Z0-9\\+\\/]{4}|[a-zA-Z0-9\\+\\/]{3}\\=|[a-zA-Z0-9\\+\\/]{2}\\=\\=)",
      "minimum":8,
      "decode":"base64",
      "unique":true,
      "collect":true
   },
   "hex":{
      "query":"(?:(?:0x|(?:\\\\)+x)[a-fA-F0-9]{2})+|[a-fA-F0-9]+",
      "minimum":12,
      "decode":"hex",
      "unique":true,
      "collect":true
   },
   "cert":{
      "query":"-----BEGIN (?:CERTIFICATE|PRIVATE KEY)-----[\\s\\S]+?-----END (?:CERTIFICATE|PRIVATE KEY)-----",
      "decode":"cert",
      "unique":true,
      "collect":true
   }
}

Make sure your regular expressions return only one capturing group, e.g., [1, 2, 3, 4]; and not a touple, e.g., [(1, 2), (3, 4)].

Make sure to properly escape regular expression specific symbols in your template file, e.g., make sure to escape dot . as \\., and forward slash / as \\/, etc.
