### Install PyZipper

Source: https://pypi.org/project/pyzipper

Install the pyzipper library using pip.

```bash
pip install pyzipper
```

--------------------------------

### Configure AES Encryption Strength and Create Zip File

Source: https://pypi.org/project/pyzipper

Use `setencryption()` to specify AES encryption strength (nbits) and `setpassword()` to set the password when creating an encrypted zip file. This example uses LZMA compression.

```python
import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                         'w',
                         compression=pyzipper.ZIP_LZMA) as zf:
    zf.setpassword(secret_password)
    zf.setencryption(pyzipper.WZ_AES, nbits=256)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")
```

--------------------------------

### Conditionally Include CRC32 Values

Source: https://pypi.org/project/pyzipper

Example of how to conditionally include CRC32 values for files with a minimum uncompressed size when creating an AES-encrypted ZIP archive. The minimum value for `min_bytes_to_include_crc` is 20.

```python
with pyzipper.AESZipFile(
    'new_test.zip',
    'w',
    compression=pyzipper.ZIP_LZMA,
) as zf:
    zf.setencryption(
        pyzipper.WZ_AES,
        conditionally_include_crc=True,
        min_bytes_to_include_crc=<minimum uncompressed bytes to include crc>,
    )
    ...
```

--------------------------------

### Configure AES Encryption Strength

Source: https://pypi.org/project/pyzipper/0.4.0

Use the setencryption() method to specify the AES encryption strength (nbits) when creating a zip file. The default is 256 bits. This example demonstrates creating a zip file with 256-bit AES encryption and writing a file to it, then reading it back.

```python
import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                         'w',
                         compression=pyzipper.ZIP_LZMA) as zf:
    zf.setpassword(secret_password)
    zf.setencryption(pyzipper.WZ_AES, nbits=256)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")

with pyzipper.AESZipFile('new_test.zip') as zf:
    zf.setpassword(secret_password)
    my_secrets = zf.read('test.txt')
```

--------------------------------

### Create and Read AES Encrypted ZIP

Source: https://pypi.org/project/pyzipper

Demonstrates how to create a new AES-encrypted ZIP file and then read a file from it. Ensure the password is provided in bytes.

```python
import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                         'w',
                         compression=pyzipper.ZIP_LZMA,
                         encryption=pyzipper.WZ_AES) as zf:
    zf.setpassword(secret_password)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")

with pyzipper.AESZipFile('new_test.zip') as zf:
    zf.setpassword(secret_password)
    my_secrets = zf.read('test.txt')
```

--------------------------------

### Create and Write to an AES Encrypted Zip File

Source: https://pypi.org/project/pyzipper/0.4.0

This snippet demonstrates how to create a new ZIP file with AES encryption and write data to it. It requires setting a password and specifying compression and encryption methods.

```python
import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                        'w',
                        compression=pyzipper.ZIP_LZMA,
                        encryption=pyzipper.WZ_AES) as zf:
    zf.setpassword(secret_password)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")
```

--------------------------------

### Read Encrypted Zip File with Password

Source: https://pypi.org/project/pyzipper

When reading an encrypted zip file, you must first set the password using `setpassword()` before attempting to read its contents.

```python
with pyzipper.AESZipFile('new_test.zip') as zf:
    zf.setpassword(secret_password)
    my_secrets = zf.read('test.txt')
```
