About pyhaveibeenpwned

Python library to query breach data providers through a unified interface. The package supports:

• haveibeenpwned (official HIBP v3 API)
• dehashed

The legacy PyHaveIBeenPwned client remains available for backward compatibility.

Release 0.3.2

• Add a provider-model API with BreachLookupClient, SearchRequest, and normalized provider results.
• Add built-in providers for haveibeenpwned and dehashed with per-provider credentials/criteria.
• Consolidate package internals into dedicated modules and use a package VERSION file as the single version source of truth.
• Update DeHashed integration to v2 API (POST /v2/search, DeHashed-Api-Key header).
• Move HIBP to direct requests.Session calls (no scraper dependency) while keeping legacy compatibility.
• Add HIBP request pacing (queries_per_second), improved optional-endpoint handling, and descriptive default User-Agent.
• Add a tracked sample client (examples/sample_client.py) with consolidated JSON reporting (--output-format json).
• Keep legacy PyHaveIBeenPwned usage available for backward compatibility.

Requirements

• Python 3.9–3.12
• Provider API keys (for example, HIBP API key and/or DeHashed API key)
• Runtime dependency: requests (installed automatically via pip)

Installation

pip3 install pyhaveibeenpwned

Sample Client Script

A tracked sample client is included at examples/sample_client.py for live checks against one provider or both providers in the same run.

Example (both providers):

HIBP_API_KEY='your_hibp_key' \
DEHASHED_API_KEY='your_dehashed_key' \
python examples/sample_client.py \
  --provider both \
  --email "[e-mail]" \
  --hibp-qps 0.15

Structured JSON output (tool-consumable):

HIBP_API_KEY='your_hibp_key' \
DEHASHED_API_KEY='your_dehashed_key' \
python examples/sample_client.py \
  --provider both \
  --email "[e-mail]" \
  --hibp-qps 0.15 \
  --output-format json \
  --output-file findings.json

JSON report top-level keys:

• schema_version
• generated_at
• target_email
• providers_requested
• provider_results
• scope
• account_hits

Example JSON output (trimmed for readability):

Usage (Provider Model)

from pyhaveibeenpwned import (
    BreachLookupClient,
    ProviderCredentials,
    SearchRequest,
    __version__,
)

print(__version__)

request = SearchRequest(
    target_email="[e-mail]",
    providers=["haveibeenpwned", "dehashed"],
    credentials_by_provider={
        "haveibeenpwned": ProviderCredentials(
            api_key="your-hibp-api-key",
            user_agent="my-company-security-tool/1.0 (+https://example.com/security-contact)",
        ),
        "dehashed": ProviderCredentials(
            api_key="your-dehashed-api-key",
            user_agent="my-company-app/1.0",
        ),
    },
    criteria_by_provider={
        "haveibeenpwned": {
            "domain": "example.com",
            "queries_per_second": 5,
        },
        "dehashed": {
            "query": r"email:{target_email}",
            "page": 1,
            "size": 100,
            "regex": False,
            "wildcard": False,
            "de_dupe": False,
        },
    },
)

response = BreachLookupClient().search(request)
hibp_result = response.results["haveibeenpwned"]
dehashed_result = response.results["dehashed"]

print(hibp_result.ok, len(hibp_result.findings))
print(dehashed_result.ok, len(dehashed_result.findings))

Notes:

• Results are returned per provider so one provider failure does not block other provider results.
• Each provider result includes normalized findings and raw provider payload.
• A global request timeout can be supplied via SearchRequest(timeout=...).
• The HIBP API requires both an API key and a User-Agent header for authenticated endpoints.
• HIBP applies strict rate limits; enabling include_pastes and include_data_classes adds extra API calls.
• HIBP provider calls are rate-paced using queries_per_second (default: 5).

Legacy Usage (Backward Compatible)

from pyhaveibeenpwned import PyHaveIBeenPwned, PyHaveIBeenPwnedError

client = PyHaveIBeenPwned(
    api_key="your-hibp-api-key",
    user_agent="my-company-security-tool/1.0 (+https://example.com/security-contact)",
)

try:
    breaches = client.get_account_breaches("[e-mail]")
except PyHaveIBeenPwnedError as exc:
    print(f"API error: {exc}")

Deprecations

Release 0.2 moves all public methods to snake_case to comply with PEP 8. Legacy camelCase helpers remain available for now and emit DeprecationWarning; update your code to use the new names before the next major release.
