Retrieve information stored in an X509 certificate.

Number of items stored in the array or -1 in case of error.

The example below shows how to display the properties of a certificate:

declarations
 info:array(S:set of string) of text
end-declarations

if x509getinfo("srv.crt",info)<1 then
 writeln("Failed to load certificate")
else
 forall(s in S | exists(info(s)))
  writeln("   ", s, ":", info(s))
end-if

This function retrieves some of the information recorded in an X509 certificate. The data is recorded in the provided array indexed by the labels of the records in the certificate. The possible labels are:

Version	Format version of the certificate
Serial	Serial number
Issuer	Issuer of the certificate
Subject	Entity associated to the public key stored in the certificate
NotBefore	Valid after this date
NotAfter	Valid until this date
SgnAlg	Algorithm used to sign the certificate

A self-signed certificate (such as those created with x509newcrt) will have identical values for Issuer and Subject.
