human-short-code 1.0.1

Replace long, unreadable ids with short human-readable code ids

Human Short Code

Encode integers into compact, human-readable codes and decode them reliably.
Useful for generating invitation codes, referral links, tracking IDs, or session tokens.

Features

• Encode numbers into fixed-length readable codes
• Decode codes back to original numbers
• Validate code format
• Customizable alphabet and length
• Mid-string hyphen for clarity

Installation

pip install human-short-code

Or install from source:

git clone https://github.com/yourusername/human-short-code.git
cd human-short-code
python -m build
pip install dist/*.whl

Usage

from human_short_code import encode, decode, verify

number = 123456789

# Encode number
code = encode(number)
print(code)  # e.g. 'QIUN-ESAD'

# Decode code
original = decode(code)
print(original)  # 123456789

# Verify code format
print(verify(code))  # True

API

encode(id_number: int, alphabet: str = ..., length: int = ...) -> str

Convert an integer into a short, fixed-length alphanumeric code.

• id_number — Integer to encode
• alphabet — Optional custom alphabet (default: "ASDEIUNWRQXBOKH")
• length — Total code length excluding hyphen (default: 8)

Returns a code string with a hyphen inserted at the center.

decode(code: str, alphabet: str = ..., length: int = ...) -> int

Decode a code string back into the original integer.

• code — Code string to decode
• alphabet — Optional custom alphabet used in encoding
• length — Expected code length excluding hyphen

Raises ValueError if invalid input.

verify(code: str, alphabet: str = ..., length: int = ...) -> bool

Check if a code is valid for the given alphabet and length.

• code — Code string to verify
• alphabet — Optional alphabet to validate against
• length — Maximum code length excluding hyphen

Returns True if valid, False otherwise.

Customization

custom_alphabet = "ABCDEFGHJKLMNPQRSTUVWXYZ"
custom_length = 6

code = encode(987654, custom_alphabet, custom_length)
print(code)  # e.g. 'BAC-DEF'

number = decode(code, custom_alphabet, custom_length)
print(number)  # 987654
