Welcome to PyEncryption this is a encryption.

This is used to encrypt all the files and directories using AES256

Python Libraries Needed:

optparse
Crypto
hashlib
base64

It is used to encrypt files and folders

Usage:

python3 pyencrypt.py [options]

Options:
    -h, --help                              show this help message and exit
    -f FILE, --file=FILE                    File to Encrypt
    -d DIRECTORY, --directory=DIRECTORY     Directory to Encrypt
    -k KEY_FILE, --key=KEY_FILE             Key file (without the extension of .key) to encrypt, defaults to key.key
    -p PATH, --path=PATH  path where the target file/directory is located (Eg., /home/Desktop if the file to encrypt is sample.txt in /home/Desktop/sample.txt)
    -e, --encrypt                           Encrypt the file/directory
    -u, --decrypt                           decrypt the file/directory
    -v, --verbose                           Verbosity of the Actions
    -l KEY_PATH, --key_path=KEY_PATH        Path where the key is located (Eg., /home/Desktop if the key is in /home/Desktop directory)

Example:

Encryption

To Encrypt sample.txt file in current directory as the encrypt.py python file

1. python3 encrypt.py -e -f sample.txt 

by default this generates the key "key.key" in current directory of the encrypt.py.

To Encrypt all files of sampledir directory in current directory as the encrypt.py python file

2. python3 encrypt.py -e -f sampledir

by default this generates the key "key.key" in current directory of the encrypt.py.

To Encrypt /home/user/sample.txt file in /home/user directory

3. python3 encrypt.py -e -f sample.txt -p /home/user

by default this generates the key "key.key" in current directory of the encrypt.py.

To Encrypt /home/user/sampledir directory in /home/user directory

4. python3 encrypt.py -u -f sampledir -p /home/user

by default this uses the key "key.key" in current directory of the encrypt.py.

Decryption

To Decrypt sample.txt file in current directory as the encrypt.py python file

5. python3 encrypt.py -u -f sample.txt 

by default this uses the key "key.key" in current directory of the encrypt.py.

To Decrypt all files of sampledir directory in current directory as the encrypt.py python file

6. python3 encrypt.py -u -f sampledir

by default this uses the key "key.key" in current directory of the encrypt.py.

To Decrypt /home/user/sample.txt file in /home/user directory

7. python3 encrypt.py -u -f sample.txt -p /home/user

by default this uses the key "key.key" in current directory of the encrypt.py.

To Decrypt /home/user/sampledir directory in /home/user directory

8. python3 encrypt.py -u -f sampledir -p /home/user

by default this uses the key "key.key" in current directory of the encrypt.py.

To use separate key, use the -k argument.

Example:

To Decrypt /home/user/sampledir directory in /home/user directory using key key2.key

9. python3 encrypt.py -u -f sampledir -p /home/user -k key2

by default this uses the key "key2.key" in current directory of the encrypt.py. Notice that the ".key" extension is not specified here. Only specify the prefix.

If you want to use the key file from some other location, then use

10. python3 encrypt.py -u -f sampledir -p /home/user -k key2 -l /home/user

This execution will use /home/user/key2.key to encrypt the files in /home/user/sampledir

To Encrypt /home/user/sample.txt directory in /home/user directory using key key2.key

11. python3 encrypt.py -e -f sample.txt -p /home/user -k key2

by default this uses the key "key2.key" in current directory of the encrypt.py. Notice that the ".key" extension is not specified here. Only specify the prefix.

If you want to see the Descriptions, use -v argument

12. python3 encrypt.py -u -f sample.txt -p /home/user -k key2 -l /home/user -v

This execution will use /home/user/key2.key to encrypt the file in /home/user/sample.txt This will print verbose output

Normal Usage

13. python3 encrypt.py -[u/e] -[f/d] [file/dir] [[-p /home/user] / blank] [[-k key2] / blank] [[-l /home/user] / blank]

Here the blank denotes that this argument is not needed if the files are in the current directory

Please store the key file somewhere safely. If lost, then it is nearly Impossible to recover the encrypted data.

UPDATE

Now inorder to avoid the problem of forgetting the key files, I've Included the functionality, that encrypts and decrypts with password.
