Simple AES

Find more information about this library HERE

An easy way to use the aes CBC mode of pycryptodome. To use this library just drag and drop the 'simpleAES.py' file into your work bench and import it to your program.

Dependencies


Check your pip version with:

pip --version

if it is for python3 then use the following command.

pip install pycryptodome

else try to use the pip3 comand:

pip3 install pycryptodome

Code examples

Automated key generation:

from simpleAES import *

key = keyGenerator()
IV = ivGenerator()

aes = simpleAES(key, IV)

text = "This is a test".encode()

ciphertext = aes.encrypt(text)
plaintext = aes.decrypt(ciphertext)

print("This is the ciphertext:", ciphertext)
print("This is the plaintext:", plaintext.decode())

Setup custom keys:

from simpleAES import *

key = "This is a key".encode()
iv = "This is an IV".encode()
salt = "This is a salt".encode()

# The hash option will hash the key with the sha256 algorithm
# and the IV with the md5 algorithm with the salt to
# prevent brute force attacks 

aes = simpleAES(key, iv, hash=True, salt=salt)

text = "This is a text".encode()

ciphertext = aes.encrypt(text)
plaintext = aes.decrypt(ciphertext)

print("ciphertext:", ciphertext)
print("plaintext:", plaintext.decode())

Store the key to a file:

from simpleAES import *

key = keyGenerator()
IV = ivGenerator()

aes = simpleAES(key, IV)

path = "key.key"

aes.extractKey(path)

Store the key to an encrypted file:

from simpleAES import *

key = keyGenerator()
iv = ivGenerator()

aes = simpleAES(key, iv)

key2 = "abcde".encode()
iv2 = "12345".encode()
salt = "qwerty".encode()

aes2 = simpleAES(key, iv , hash=True, salt=salt)

path="encryptedKey.key"

#It will encrypt the file with the 'aes2' object.

aes.extractEncryptedKey(aes2, path)

Load the key from file:

from simpleAES import *

path = "key.key"

data = loadKeyFromFile(path)

key = data[0]
IV = data[1]

# When you load a key from file do not set the 
# hash value to True or use the salt option,
# because in the file are stored the hashed values and not
# the original keywords.

aes = simpleAES(key, IV)

Load the key from encrypted file:

key = "abcde".encode()
iv = "12345".encode()
salt = "qwerty".encode()

aes = simpleAES(key, iv, hash=True, salt=salt)

path="encryptedKey.key"

data = loadKeyFromEncryptedFile(aes, path)

key = data[0]
iv = data[1]

aes = simpleAES(key, iv)
