### Mostly get help by help( ... ) in ipython

*Example*

```
In [9]: from fastutils import strutils

In [10]: help(strutils.random_string)
Help on function random_string in module fastutils.strutils:

random_string(length, choices='abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ')

```

### Some function using *args, **kwargs paramters, see help below.

### cipherutils.IvCipher

*Instance Init Parameters*

- password: required.

### cipherutils.IvfCipher

*Instance Init Parameters*

- password: required.
- result_encoder: default to cipherutils.RawDataEncoder(), choices are: cipherutils.HexlifyEncoder(), cipherutils.Base64Encoder(), cipherutils.SafeBase64Encoder().
- kwargs: dict type.
   - int_digits: default to 12
   - float_digits: default to 4

*Note*

- When float_digits=0, the plain number is treat as integer value.

### cipherutils.AesCipher

*Instance Init Parameters*

- password: required.
- result_encoder: default to cipherutils.RawDataEncoder(), choices are: cipherutils.HexlifyEncoder(), cipherutils.Base64Encoder(), cipherutils.SafeBase64Encoder(), cipherutils.Utf8Encoder(),

   - mode: default to AES.MODE_ECB (from Crypto.Cipher import AES).

*Example*

```shell
In [1]: from fastutils import cipherutils

In [2]: cipher = cipherutils.AesCipher(password="testpwd", result_encoder=cipherutils.HexlifyEncoder(), kwargs={"key": cipherutils.mysql_aes_key}, force_text=True)
   ...:

In [3]: text1 = "test content"

In [4]: text2 = cipher.encrypt(text1)

In [5]: print(text2)
299aa4e15a40d69e56674a94d9b66cc3
