Member Function Documentation

AddSignedTfd()

static int firmasat::Tfd::AddSignedTfd ( const std::string &  outFile, const std::string &  inputFile, const std::string &  keyFile, const std::string &  password, const std::string &  certFile  )

static

Add a signed Timbre Fiscal Digital (TFD) element to a CFDI document.

Parameters

outFile	Name of new file to be created.
inputFile	Name of existing CFDI file
keyFile	Name of private key file.
password	Password for private key file.
certFile	Name of PAC's X.509 certificate that matches the keyFile (required)

Returns

0 if successful or nonzero error code if failed.

Remarks

The inputFile must be a version 3.2/3.3 CFDi document already signed with a sello/Sello field and no existing TFD element. The TFD will be timestamped using the system clock and a fresh UUID will be generated. No other XML processing is carried out except inserting the TFD element.

Note

The SelloSAT value will be different each time.

ExtractDigestFromSignature()

static std::string firmasat::Tfd::ExtractDigestFromSignature ( const std::string &  xmlFile, const std::string &  certFile  )

static

Extract message digest from the selloSAT node in Timbre Fiscal Digital of CFDI document.

Parameters

xmlFile	Name of XML file to be processed (or a string containing XML data).
certFile	X.509 certificate file of PAC who signed the TFD (required).

Returns

Message digest in hex format or empty string on error.

MakeDigestFromXml()

static std::string firmasat::Tfd::MakeDigestFromXml ( const std::string &  xmlFile )

static

Form message digest of cadena original del Timbre Fiscal Digital del SAT (TFD piped string) from CFDI XML file.

Parameters

xmlFile

Name of XML file to be processed (or a string containing XML data).

Returns

Message digest in hex format or empty string on error.

MakePipeStringFromXml()

static std::string firmasat::Tfd::MakePipeStringFromXml ( const std::string &  xmlFile )

static

Create the cadena original del Timbre Fiscal Digital del SAT (TFD piped string) from CFDI XML file.

Parameters

xmlFile

Name of XML file to be processed (or a string containing XML data).

Returns

Piped string (UTF-8 encoded).

MakeSignatureFromXml()

static std::string firmasat::Tfd::MakeSignatureFromXml ( const std::string &  xmlFile, const std::string &  keyFile, const std::string &  password  )

static

Extract message digest from the selloSAT node in Timbre Fiscal Digital of CFDI document.

Parameters

xmlFile	Name of XML file to be processed (or a string containing XML data).
keyFile	Name of private key file or string with PEM representation.
password	Password for private key file.

Returns

Signature in base64 format or empty string on error.

VerifySignature()

static int firmasat::Tfd::VerifySignature ( const std::string &  xmlFile, const std::string &  certFile  )

static

Verify the selloSAT signature in CFDI XML document.

Parameters

xmlFile	Name of XML file to be processed (or a string containing XML data).
certFile	X.509 certificate file of PAC who signed the TFD (required).

Returns

Zero if signature is verified or a nonzero error code if failed.
