<Result> = CertificateSignFile(<File path> , <Certificate> [, <Signature file>])
<Result>: Buffer
Signature of the file. This buffer can be used later by CertificateCheckBufferSignatureFile to check the correspondence between the signature and the file.
<File path>: Character string (with quotes)
Name and full (or relative) path of the file for which a signature will be created.
<Certificate>: Certificate variable
Name of Certificate variable containing the certificate that will be used to create the signature of the file.
<Signature file>: Optional character string (with quotes)
Name and full (or relative) path of the file containing the signature. This file can be used later by CertificateCheckFileSignatureFile to check the correspondence between the signature and the file.

Validity of certificate

Before signing a file, it is advisable to check the validity of the Certificate (Property ValidForSignature of the Variable type Certificate). This property is used to find out whether the certificate owns a private key as well as all the characteristics required to perform a signature. CertificateSignFile returns an error if this property is set to False.
