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 type:

pip install pycryptosimple-aes

Code examples

Automated key generation:

from pycryptosimple_aes 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 pycryptosimple_aes 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 pycryptosimple_aes import *

key = keyGenerator()
IV = ivGenerator()

aes = simpleAES(key, IV)

path = "key.key"

aes.extractKey(path)

Store the key to an encrypted file:

from pycryptosimple_aes 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 pycryptosimple_aes 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)
