Struct SignatureVerifier 

pub struct SignatureVerifier { /* private fields */ }

Available on crate feature signatures only.

Verifier for PDF digital signatures.

Implementations

impl SignatureVerifier

pub fn new() -> Self

Create a new signature verifier.

pub fn add_trusted_root(&mut self, cert_der: Vec<u8>)

Add a trusted root certificate.

pub fn add_trusted_roots(&mut self, certs: Vec<Vec<u8>>)

Add multiple trusted root certificates.

pub fn load_system_roots(&mut self) -> Result<usize>

Load system root certificates.

pub fn extract_signature_info(&self, sig_dict: &Object) -> Result<SignatureInfo>

Extract signature information from a signature dictionary.

pub fn verify( &self, pdf_data: &[u8], sig_dict: &Object, contents: &[u8], ) -> Result<VerificationResult>

Verify a signature end-to-end.

Runs the RSA-PKCS#1 v1.5 signer-attributes check and the messageDigest content-integrity check (via crate::signatures::verify_signer_detached), then enriches the result with certificate trust, expiration, and DN metadata extracted from the embedded signer certificate.

Digest algorithm is driven by the CMS blob’s signer.digest_alg (SHA-1 / SHA-256 / SHA-384 / SHA-512), so PDFs that don’t use SHA-256 — still common with PAdES — are covered.

pub fn quick_check(&self, sig_dict: &Object) -> Result<bool>

Quick check if a signature appears valid (without full cryptographic verification).

Trait Implementations

impl Default for SignatureVerifier

fn default() -> Self

Returns the “default value” for a type.
