Detailed Description

This class computes a CMS signature according to RFC 5652.

Constructor & Destructor Documentation

Load X.509 certificate and supply a ASN.1 DER encoded private key.

Parameters

cert	ASN.1 DER encoded X.509 certificate
pkey	ASN.1 DER encoded private key (PKCS#1 or PKCS#8) formats. It can be empty. In that case signing can be supplied by a signing service, or performing a deferred signing

Load a X.509 certificate without supplying a private key.

Parameters

cert	ASN.1 DER encoded X.509 certificate

Remarks: signing can be supplied by a signing service, or performing a deferred signing

void PdfSignerCms::AddAttribute	(	const std::string_view &	nid,
		const bufferview &	attr,
		PdfSignatureAttributeFlags	flags = `PdfSignatureAttributeFlags::None`
	)

Add a signature attribute with given identifier from the input.

Parameters

nid	the numerical identifier
attr	the attribute bytes. By default, the bytes are parsed for valid ASN.1 input

void PdfSignerCms::ReserveAttributeSize ( unsigned attrSize )

Reserve some size in the final signature.

It is used in dry-runs to enlarge the signature buffer
