class HexaPDF::DigitalSignature::Handler

Parent	Object

The base signature handler providing common functionality.

Specific signature handlers need to override methods if necessary and implement the needed ones that don’t have a default implementation.

signature_dict[R]¶

The signature dictionary used by the handler.

new(signature_dict)¶

Creates a new signature handler for the given signature dictionary.

certificate_chain()¶

Returns the certificate chain.

Needs to be implemented by specific handlers.

signer_certificate()¶

Returns the certificate used for signing.

Needs to be implemented by specific handlers.

signer_name()¶

Returns the common name of the signer (/Name field of the signature dictionary).

signing_time()¶

Returns the time of signing (/M field of the signature dictionary).

verify(store, allow_self_signed: false)¶

Verifies general signature properties and prepares the provided OpenSSL::X509::Store object for use by concrete implementations.

Needs to be called by specific handlers.

check_certified_signature(result)¶

Sets an informational message on result whether the signature is a certified signature.

store_verification_callback(result, allow_self_signed: false)¶

Returns the block that should be used as the OpenSSL::X509::Store verification callback.

result: The VerificationResult object that should be updated if problems are found.
allow_self_signed: Specifies whether self-signed certificates are allowed.

verify_signing_time(result)¶

Verifies that the signing time was within the validity period of the signer certificate.
