A python SDK for Criipto Signatures.

Examples

Getting started

Requirements

This library supports python 3.13 and later.

Installation

The SDK is available on PYPI:

python3 -m pip install criipto-signatures

Configure the SDK

The SDK is available in both a sync and an async version

from criipto_signatures import (
  CriiptoSignaturesSDKAsync,
  CriiptoSignaturesSDKSync,
)
asyncClient = CriiptoSignaturesSDKAsync(
    '{YOUR_CRIIPTO_CLIENT_ID}',
    '{YOUR_CRIIPTO_CLIENT_SECRET}'
)
syncClient = CriiptoSignaturesSDKSync(
    '{YOUR_CRIIPTO_CLIENT_ID}',
    '{YOUR_CRIIPTO_CLIENT_SECRET}'
)

Overriding the GraphQL endpoint

By default the SDK targets https://signatures.idura.app/v1/graphql. You can override the endpoint by passing an endpoint argument to either client:

from criipto_signatures import CriiptoSignaturesSDKAsync

client = CriiptoSignaturesSDKAsync(
    '{YOUR_CRIIPTO_CLIENT_ID}',
    '{YOUR_CRIIPTO_CLIENT_SECRET}',
    endpoint='https://signatures.idura.app/v1/graphql',
)

Basic example

from criipto_signatures import CriiptoSignaturesSDKAsync
from criipto_signatures.models import (
    CreateSignatureOrderInput,
    DocumentInput,
    PadesDocumentInput,
    DocumentStorageMode,
    AddSignatoryInput,
    CloseSignatureOrderInput,
)

client = CriiptoSignaturesSDKAsync(
    '{YOUR_CRIIPTO_CLIENT_ID}',
    '{YOUR_CRIIPTO_CLIENT_SECRET}'
)

# Create signature order
signatureOrder = await client.createSignatureOrder(
    CreateSignatureOrderInput(
        documents=[
            DocumentInput(
                pdf=PadesDocumentInput(
                    title="My document",
                    blob=data, # bytes object, or a base64 encoded string
                    storageMode=DocumentStorageMode.Temporary,
                )
            )
        ]
    )
)

# Add signatory to signature order
signatory = await client.addSignatory(
    AddSignatoryInput(
        signatureOrderId=signatureOrder.id
    )
)
print(signatory.href)

# ... Wait for the signatory to sign

# And close the order
await client.closeSignatureOrder(
    CloseSignatureOrderInput(
        signatureOrderId=signatureOrder.id,
        retainDocumentsForDays=1
    )
)
