AdES

A C++ library for Windows to create CAdES (B,T,C,X,XL), XAdES (B-T,C,X,XL) and PAdES (B-B,B-T,B-XL) messages. Also supports ASiC-S and ASiC-E with both CAdES and XAdES. 100% ETSI Compliant.

CAdES

Quick guide:

HRESULT Sign(LEVEL lev,const char* data,DWORD sz,const std::vector<CERT>& Certificates, SIGNPARAMETERS& Params,std::vector<char>& Signature);
HRESULT Verify(const char* data, DWORD sz, LEVEL& lev,const char* omsg = 0,DWORD len = 0,std::vector<char>* msg = 0,std::vector<PCCERT_CONTEXT>* Certs = 0,VERIFYRESULTS* vr = 0);

Where

• lev, enumeration from LEVEL: CMS,B,T,C,X or XL
• data/sz, the data to sign
• Certificates, a list of certificates to use for signing. Each CERT contains the certificate, CRLs, and more validation certificates
• Params, additional parameters, including timestamp server, policy, commitment type, attach method etc.

In Verify()

• data/sz, the signature to verify
• lev, gets the detected level
• omsg/len, the original data if the signature was detached
• msg/certs/results, returned message, certificates used, and other data (policy, commitment type etc)

XAdES

Quick guide:

struct FILEREF
{
	const char* data = 0; // pointer to data
	DWORD sz = 0; // size, or 0 if null terminated XML
	const char* ref = 0;
	std::string mime = "application/octet-stream";
};
HRESULT XMLSign(LEVEL lev, std::vector<FILEREF>& data,const std::vector<CERT>& Certificates,SIGNPARAMETERS& Params, std::vector<char>& Signature);

// Currently XMLDSIG only
HRESULT XMLVerify(const char* xmldata, LEVEL& lev, ATTACHTYPE& att, const char* omsg, DWORD len, bool WasDetachedCanonicalized,std::vector<PCCERT_CONTEXT> * Certs, VERIFYRESULTS * vr);

PAdES

Quick guide:

HRESULT PDFSign(LEVEL lev,const char* data,DWORD sz,const std::vector<CERT>& Certificates, SIGNPARAMETERS& Params,std::vector<char>& Signature);

ASiC

Quick guide:

HRESULT ASiC(ALEVEL alev,ATYPE typ, LEVEL lev,std::vector<FILEREF>& data,std::vector<CERT>& Certificates, SIGNPARAMETERS& Params, std::vector<char>& fndata);

EXE

Quick guide:

HRESULT PESign(LEVEL lev,const char* data,DWORD sz,const std::vector<CERT>& Certificates, SIGNPARAMETERS& Params,std::vector<char>& Signature);
