Search for Digital e-Signatures Leave feedback
GroupDocs.Signature provides the ability to search for digital electronic signatures in documents. Digital signatures provide a way to verify the authenticity and integrity of a document by using cryptographic techniques.
The Signature class provides the Search method which allows you to search for digital signatures in documents. Here’s how to use it:
- Create a new instance of the Signature class and pass the source document path as a parameter.
- Create an instance of DigitalSearchOptions class.
- Call the Search method of the Signature class instance and pass the search options to it.
- Process the search results.
Here’s an example of how to search for digital signatures in a document:
from groupdocs.signature import Signature
from groupdocs.signature.options import DigitalSearchOptions
from groupdocs.signature.domain import DigitalSignature
# Initialize Signature with input document
with Signature("sample.pdf") as signature:
# Create search options
search_options = DigitalSearchOptions()
# Search for signatures
result = signature.search(search_options)
# Process found signatures
print(f"Found {len(result)} digital signatures")
for digital_signature in result:
print(f"Subject: {digital_signature.subject}")
print(f"Issuer: {digital_signature.issuer}")
print(f"Valid From: {digital_signature.valid_from}")
print(f"Valid To: {digital_signature.valid_to}")
You can customize the search process by setting specific options:
from groupdocs.signature import Signature
from groupdocs.signature.options import DigitalSearchOptions
from groupdocs.signature.domain import DigitalSignature
# Initialize Signature with input document
with Signature("sample.pdf") as signature:
# Create search options
search_options = DigitalSearchOptions()
# Set search criteria
search_options.subject = "John Doe" # Search for specific subject
search_options.issuer = "Certificate Authority" # Search for specific issuer
# Search for signatures
result = signature.search(search_options)
# Process found signatures
print(f"Found {len(result)} digital signatures")
for digital_signature in result:
print(f"Subject: {digital_signature.subject}")
print(f"Issuer: {digital_signature.issuer}")
print(f"Valid From: {digital_signature.valid_from}")
print(f"Valid To: {digital_signature.valid_to}")
