使用 python regex 從此字符串中提取證書、私鑰和證書鏈

Question

我有這個字符串（顯然我從所有 3 行中剪掉了一些行，以免暴露自己）。 我希望 python 從中提取：

中級證書

鑰匙

公開證書

並將它們寫入 3 個單獨的文件，如上命名。

我正在嘗試使用這個正則表達式，但它將所有這些都結合在一起。

match1 = re.findall(r"Intermediate cert((.|\\n)*)(-----END CERTIFICATE-----)",strsecret,re.MULTILINE)

    (GetSecretResult){
Errors = ""
Secret =
  (Secret){
     Name = "new cert"
     Items =
        (ArrayOfSecretItem){
           SecretItem[] =
              (SecretItem){
                 Value = "new cert"
                 Id = 1470
                 FieldId = 334
                 FieldName = "E-Mail"
                 IsFile = False
                 IsNotes = False
                 IsPassword = False
                 FieldDisplayName = "E-Mail"
              },
              (SecretItem){
                 Value = "no password"
                 Id = 1471
                 FieldId = 335
                 FieldName = "Password"
                 IsFile = False
                 IsNotes = False
                 IsPassword = True
                 FieldDisplayName = "Password"
              },
              (SecretItem){
                 Value = None
                 Id = 1472
                 FieldId = 336

                 IsFile = False
                 IsNotes = False
                 IsPassword = False
                 FieldDisplayName = "Account ID"
              },
              (SecretItem){
                 Value = None
                 Id = 1473
                 FieldId = 337
                 FieldName = "Sign-in Link"
                 IsFile = False
                 IsNotes = False
                 IsPassword = False
                 FieldDisplayName = "Sign-in Link"
              },

Answer 1

試試下面的正則表達式： (-----BEGIN .+?-----(?s).+?-----END .+?-----) 。 你可以在這里試一試。 這通過在開始和結束之后進行延遲匹配以及在兩者之間進行延遲匹配來實現。
