What is it?

A fast and unbreakable encrytion system. This library has 4 functions, makeid, encrypt, decrypt, and bitarray_to_text.

makeid will generate a long, virtually collision-proof identifier.

These tools can be very useful in login systems.

It also includes a (probably insecure) custom hash function in PCSS.hash.

Installation

You can install it with pip. pip install Projxon-Cyber-Security-System

Usage

Encrypt and Decrypt

from PCSS import encrypt, decrypt, makeid, bitarray_to_text
from PCSS.hash import hash

print(f"""
Hash of Hi!: {hash("Hi!", 256)}
Hash of Hello_World!: {hash("Hello_World!", length=256)}
Hash of Hello_World! : {hash("Hello_World! ", length=256)}
Hash of Hello World: {hash("Hello World", length=256)}
Hash of Password#123: {hash("Password#123", length=256)}
Hash of AAAAAAAAAAAA: {hash("AAAAAAAAAAAA", length=256)}
Hash of AAAAAAAAAAAB: {hash("AAAAAAAAAAAB", length=256)}
Hash of !#!#!#!#!#!#!#!#: {hash("!#!#!#!#!#!#!#!#", length=256)}
""")

# Output:

## Encryption

text = "Hello World!"
key = "key"

# Encrypt the text
encrypted_bitarray = encrypt(text, key)
print(encrypted_bitarray)

# Decrypt the bitarray
decrypted_bitarray = decrypt(encrypted_bitarray, key)

# Convert it back to a string.
decrypted_text = bitarray_to_text(decrypted_bitarray)

print(decrypted_text, text == decrypted_text)

Generate id

from PCSS import makeid

print(makeid())

# ids will vary.

These ids are garunteed to be unique; the chance of collision is about 1 / (2.42721841x10^229). For reference, the number of atoms in the universe is estimated to be 10^78.

Documentation:

PCSS

encrypt(data: Union[str, bytes, bitarray], key: Union[str, bytes, bitarray, None]=None, final_key: Union[bitarray, None]=None, rounds=None, salt=None) -> bitarray

Encrypts data using an advanced method including XOR encrytion and byte and bit reversal. salt will defualt to the key.

decrypt(encrypted_data: Union[str, bytes, bitarray], key: Union[str, bytes, bitarray, None]=None, final_key: Union[bitarray, None]=None, rounds=None, salt=None) -> bitarray

Decrypts data that was encrypted using the PCSS.encrypt function. Parameters that do not match will generate an incorrect output.

makeid()

Generates a long and secure id. These ids are garunteed to be unique; the chance of collision is about 1 / (2.42721841x10^229). For reference, the number of atoms in the universe is estimated to be 10^78.

bitarray_to_text(data: bitarray) -> str

Converts a bitarray to a string.

PCSS.hash

hash(data: Union[str, int, bitarray, bytes], length: int = 256, block_size: int = 2, affected_area: int = 0.5, output: str = "hex") -> Union[bitarray, str, int, bytes]

Hashes data using the hashing PCSS algorithm. The length of the hash is supplied as the length arguemnt and it must be divisible by the block size (which defaults to 4). An increased block size results in increased randomness.

affected_area is the number of input blocks used in the output block calculation. If it is an integer, it represents a concrete value, and if it is between 0 and 1 it is proportional to the number of blocks. This value is very particular, be careful!

Output can be "hex", "bitarray", "bytes", "base64", "base64-bytes", or "int".
