pip install ez-crypt-tool

USE

ez_crypt_tool

Option	Description
--genkey	Generates a key, that can be used for encryption and decryption.
--genkeyfile	Will generate a key and put it in the DEFAULT_KEY_FILE: ~/.ezcrypt/.ezcrypt.key.
--keyfile:	Is supplied, will be used for Fernet key.
--encrypt:	Uses the key in the KEY_FILES to encrypt a clear text string.
--decrypt	Uses the key in the KEY_FILES to decrypt a cipher string.

KEY_FILES: ['.ezcrypt.key', './conf/.ezcrypt.key', '~/.ezcrypt/.ezcrypt.key'] ENV: Environment can be used, skipping key file. Example: export EZCRYPT_KEY=

Step 1: Generate Key or Key File

ez_crypt_tool --genkey
NQYiJixqOhkFWOESyttUvP4ChIcNehpTiyXMGA0eifA=

or

ez_crypt_tool --genkeyfile
NQYiJixqOhkFWOESyttUvP4ChIcNehpTiyXMGA0eifA=

Step 2: Place key in file

Place the key into the ezcrypt.key file, then put the file in one of the 3 locations listed above in KEY_FILES.

Step 3: Use command to encrypt password

ez_crypt_tool --encrypt mypassword
Encrypted:gAAAAABi6DbHCEwLiKHIrolX_oUGA9k-3RjB08-5VW0-lg4FdvGgsiwe1HriMkhLfWRFnMJsbJRvmpULEHbu2Q_EQbFDWaPBxA==

Step 4: Store encrypted password

Place encrypted password in configuration file that can be retrieved by the application.

See example under ./sandbox directory.

Notes

• A prefix of "fenc:" can be prepended to key, to denote encrypted string. Not required.
• This project uses an example example test key.
• The key file [.ezcrypt.key] is in the conf directory.
• Its only for this example and can be used by others to decyrpt your informaiton.

!!! DO NOT REUSE THE INCLUDED KEY !!! GENERATE A NEW KEY BEFORE USING EzCryptTool in your environment

Prerequisites (IMPORTANT)

Code Examples

EzCryptTool Python Code

---

# Import EzCrypt
from ez_crypt_tool.ez_crypt_tool import EzCryptTool

# Initialize the EzCryptTool
ezc = EzCryptTool.get_instance()

# Starting with clear text string
clear_text_pw = "MyCoolPassword"
print(f"Clear Text: {clear_text_pw}")

# Encrypting the string
crypted_password = ezc.encrypt(clear_text_pw)
print(f"Encrypted: {password}")

# decrypting the string
clear_text_pw = ezc.decrypt(crypted_password)
print(f"Decrypted: {clear_text_pw}")

Output

Clear Text: MyCoolPassword
Encrypted: fenc:gAAAAABjk4vdeenLsvEp_WXKCD_pw2a0oNaSI11l-5WLIdAJH4X579N8GOyYHefEPeR03yJymwoViqba9jBWucKHc4ffoev7Eyyn3O7wx3LmyUqRznut8Cw=
Decrypted: MyCoolPassword
