presidio-hardened-requests

A 100% drop-in replacement for the Python requests library with automatic Presidio security hardening (v0.2.1).

# Before (plain requests — no security hardening)
import requests

# After (Presidio hardening — zero code changes needed)
import presidio_requests as requests

Every call you already make — requests.get(), requests.post(), Session(), etc. — keeps working exactly the same, with security hardening applied transparently underneath.

Security Features (v0.2.0)

Installation

pip install presidio-hardened-requests

For development (includes pip-audit):

git clone https://github.com/presidio-v/presidio-hardened-requests.git
cd presidio-hardened-requests
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"

v0.2.1 Highlights

• Security patch: requires certifi>=2026.10.19, so verify=True no longer trusts emSign ECC Root CA - G3 (eMudhra intermediates with trivially recoverable keys, Mozilla bug 2083449). requests does not check revocation, so only the bundle removal protects callers.

v0.2.0 Highlights

• Sink-enforced secret redaction via RedactingFilter (installed automatically on the logger).
• Improved redaction coverage in request logging (params, data, json bodies).
• pip-audit added to dev extras and CI pipeline.
• Dependency floors raised; docs aligned with actual implementation (TLS 1.2+, pinning limitations noted).
• All core Presidio security extensions from PRESIDIO-REQ.md now delivered or clearly documented.

Usage

Basic — Zero Code Changes

import presidio_requests as requests

# All your existing code works unchanged
resp = requests.get("https://httpbin.org/get")
print(resp.json())

Secret Redaction in Action

import logging
import presidio_requests as requests

logging.basicConfig(level=logging.DEBUG)

# The Bearer token is automatically redacted in all logs
resp = requests.get(
    "https://httpbin.org/get",
    headers={"Authorization": "Bearer sk-proj-SUPER_SECRET_KEY"},
)
# Log output shows: Authorization: Bearer ***REDACTED***

Compared to Plain requests

# --- Plain requests (INSECURE) ---
import requests

# ✗ No TLS enforcement — silently allows http://
requests.get("http://api.example.com/data")

# ✗ Secrets visible in logs
requests.get("https://api.example.com?api_key=sk_live_abc123")

# ✗ No rate limiting — can overwhelm servers
for i in range(10000):
    requests.get("https://api.example.com/data")

# --- presidio-hardened-requests (SECURE) ---
import presidio_requests as requests

# ✓ Auto-upgrades to https://
requests.get("http://api.example.com/data")

# ✓ api_key redacted in all logs
requests.get("https://api.example.com?api_key=sk_live_abc123")

# ✓ Per-host rate limiting with backoff
for i in range(10000):
    requests.get("https://api.example.com/data")

Advanced — HardenedSession

from presidio_requests import HardenedSession, SecretRedactor, RateLimiter

session = HardenedSession(
    redactor=SecretRedactor(placeholder="[SCRUBBED]"),
    rate_limiter=RateLimiter(max_requests_per_second=5.0),
    pinned_certs={"api.example.com": "abcdef1234567890..."},
    enforce_tls=True,
)

resp = session.get("https://api.example.com/v1/users")

CVE Quick-Check

from presidio_requests import check_cve

warnings = check_cve()
if warnings:
    for w in warnings:
        print(f"⚠ {w}")
else:
    print("✓ Installed requests version is clean")
