> Library to use eFirma (fiel) and CSD (sellos) from SAT

🇺🇸 The documentation of this project is in spanish as this is the natural language for intended audience.

🇲🇽 La documentación del proyecto está en español porque ese es el lenguaje principal de los usuarios.

Esta librería ha sido creada para poder trabajar con los archivos CSD y FIEL del SAT. De esta forma, se simplifica el proceso de firmar, verificar firma y obtener datos particulares del archivo de certificado así como de la llave pública.

- El CSD (Certificado de Sello Digital) es utilizado para firmar Comprobantes Fiscales Digitales.
- La FIEL (o eFirma) es utilizada para firmar electrónicamente documentos (generalmente usando XML-SEC) y está reconocida por el gobierno mexicano como una manera de firma legal de una persona física o moral.

Con esta librería no es necesario convertir los archivos generados por el SAT a otro formato, se pueden utilizar tal y como el SAT los entrega.
