ciphyrs 2.0.0

Python SDK for the Ciphyrs PII Shield API

Ciphyrs — PII Shield for AI Workflows

Intercept, mask, and restore PII before it reaches any LLM. Works with LangChain, CrewAI, or any Python application.

Install

pip install ciphyrs                  # core SDK
pip install 'ciphyrs[langchain]'     # + LangChain integration
pip install 'ciphyrs[crewai]'        # + CrewAI integration
pip install 'ciphyrs[all]'           # everything

Quick Start

from ciphyrs import CiphyrsClient

client = CiphyrsClient(
    api_key="cyp_live_...",
    base_url="https://www.ciphyrs.com"
)

# Mask PII
result = client.mask("Contact Praveen at 9876125640 and [e-mail]")
print(result.masked_text)
# "Contact XXXX_a1b2c3 at XXXX_d4e5f6 and XXXX_g7h8i9"

# Restore PII
restored = client.restore(result.masked_text, result.session_id)
print(restored.restored_text)
# "Contact Praveen at 9876125640 and [e-mail]"

Authentication

All API calls require an x-api-key header. Get your API key from the Ciphyrs Dashboard.

1. Register at ciphyrs.com/register
2. Go to Settings > API Keys
3. Click Generate API Key
4. Copy the key (starts with cyp_live_)

LangChain Integration

Option 1: Callback Handler (auto-masks all LLM calls)

from langchain_openai import ChatOpenAI
from ciphyrs.integrations.langchain import CiphyrsPIICallback

callback = CiphyrsPIICallback(api_key="cyp_live_...")
llm = ChatOpenAI(model="gpt-4o", callbacks=[callback])

# PII is automatically masked before reaching OpenAI
# and restored in the response
result = llm.invoke("Hi, I'm Praveen Kumar, my phone is 9876125640")

Option 2: LCEL Runnables (pipe operator)

from ciphyrs.integrations.langchain import CiphyrsMaskRunnable, CiphyrsRestoreRunnable

session = {}
mask = CiphyrsMaskRunnable(api_key="cyp_live_...", session_store=session)
restore = CiphyrsRestoreRunnable(api_key="cyp_live_...", session_store=session)

# Build pipeline: mask -> prompt -> llm -> restore
chain = mask | prompt_template | llm | restore
result = chain.invoke({"input": "Call Praveen at 9876125640"})

Option 3: Shield Wrapper (wrap any chain)

from ciphyrs.integrations.langchain import CiphyrsShield

shield = CiphyrsShield(api_key="cyp_live_...")
safe_chain = shield.wrap(my_existing_chain)
result = safe_chain.invoke({"input": "Praveen's email is [e-mail]"})

Async Support

from ciphyrs import AsyncCiphyrsClient

async with AsyncCiphyrsClient(api_key="cyp_live_...") as client:
    result = await client.mask("Contact Praveen at [e-mail]")
    restored = await client.restore(result.masked_text, result.session_id)
