SSL Certificate Temporary Folder Management Utility

cert2temp

SSL Certificate Temporary Folder Management Utility

Problem Solved

Solves SSL certificate verification failures caused by non-ASCII characters (Korean, spaces, special characters) in certificate file paths. Automatically creates safe ASCII-only temporary folders for each platform to copy certificates.

Supported Platforms

• Windows: C:\Temp (always ASCII)
• Linux: /tmp (already ASCII)
• macOS: /tmp (already ASCII)
• Others: System default temporary directory

Installation

pip install cert2temp

Usage

Basic Usage

from cert2temp import get_safe_cert_path, cleanup_temp_cert

# Copy certificate file to safe path
safe_cert_path = get_safe_cert_path(original_cert_path)

# Use for SSL requests
import requests
response = requests.get(url, verify=safe_cert_path)

# Clean up after use
cleanup_temp_cert(safe_cert_path)

Using with requests Session

from cert2temp import get_requests_session_with_safe_cert

# Create requests session with safe certificate
session = get_requests_session_with_safe_cert()
response = session.get(url)

Using with Yahoo Finance API

import yfinance as yf
from cert2temp import get_requests_session_with_safe_cert

# Bypass Yahoo Finance 429 errors with curl_cffi session
session = get_requests_session_with_safe_cert()
ticker = yf.Ticker("AAPL", session=session)
data = ticker.history(period="1mo")

API Reference

get_safe_cert_path(cert_path=None)

Copy certificate file to temporary folder and return safe path.

Parameters:

• cert_path (str, optional): Original certificate file path. Uses default certificate if None

Returns:

• Safe certificate file path (str)

cleanup_temp_cert(cert_path)

Clean up temporary certificate file.

Parameters:

• cert_path (str): Temporary certificate file path

Returns:

• True if cleanup successful, False otherwise (bool)

cleanup_all_temp_certs()

Clean up all temporary certificate files.

Returns:

• Number of files cleaned up (int)

get_requests_session_with_safe_cert(cert_path=None)

Create a requests session using safe certificate path.

Parameters:

• cert_path (str, optional): Original certificate file path

Returns:

• requests.Session object

get_platform_safe_temp_dir()

Returns a safe ASCII-only temporary directory path for each platform.

Returns:

• Platform-specific safe temporary directory Path object

Advanced Features

Smart Folder Cleanup

cert2temp handles temporary folder cleanup intelligently:

• Original folders: Preserved (user folders)
• Empty folders we created: Removed (automatic cleanup)

Multi-platform Support

Works with the same API on all major platforms:

# Windows uses C:\Temp
# Linux/macOS uses /tmp
safe_dir = get_platform_safe_temp_dir()

Caching Feature

Copies and reuses the same certificate file only once:

# First call: File copy
path1 = get_safe_cert_path("cert.pem")

# Second call: Return cached path
path2 = get_safe_cert_path("cert.pem")
assert path1 == path2  # True
