LibFcrypt

Simple, symmetric encryption. Courtesy of cryptography and Fernet.

Functions

Base

• base.check_key(key): Check a key's (bytes) validity, returns a boolean.
• base.gen_key(): Generate a bytes object key.
• base.passwd_gen_key(passwd): Generate a bytes object key derived from a string.
• base.encrypts(key,string): Encrypt a string using a key (bytes), returns a bytes object.
• base.encryptb(key,dataBytes): Encrypt a bytes object using a key (bytes), returns a bytes object.
• base.decrypts(key,string): Decrypt a bytes object using a key (bytes), returns a string.
• base.decryptb(key,byteString): Decrypt a bytes object using a key (bytes), returns a bytes object.

File

• file.encryptf(key,filePtr): Encrypt the contents of a file using a key (bytes), returns a bytes object.
• file.encryptbf(key,filePtr): Encrypt the contents of a file using a key (bytes), returns a bytes object.
• file.decryptf(key,filePtr): Decrypt the contents of a file using a key (bytes), returns a string.
• file.decryptbf(key,filePtr): Decrypt the contents of a file using a key (bytes), returns a bytes object.

Variables

• VERSION: Module version information, string.
• LICENSE: Module licensing information, string.

Errors

• errors.InvalidKey: Should be raised when base.check_key() returns False.

Installation

Git

git clone https://www.github.com/SrFluff/libfcrypt
cd libfcrypt
cp -r libfcrypt $PYTHONPATH

Pip

pip install libfcrypt

import libfcrypt

# Generate a key
key = libfcrypt.base.gen_key()

# Generate a key from a password
other_key = libfcrypt.base.passwd_gen_key("Password123")

# Encrypt a string
secrets = libfcrypt.base.encrypts(key,"I have so many secrets muahaha!")

# Encrypt a bytes object
bSecrets = libfcrypt.base.encryptb(key,b'ID3')

# Write secrets to a file
with open("Secrets.txt","wb") as f:
    f.write(secrets)

# Read secrets from a file

f = open("Secrets.txt","rb")
spilled_secrets = libfcrypt.file.decryptf(key,f)

# Spill secrets!

print(spilled_secrets)
