NAME
     X509_CINF_new, X509_CINF_free, X509_VAL_new, X509_VAL_free,
     X509_CERT_AUX_new, X509_CERT_AUX_free - X.509 certificate information
     objects

SYNOPSIS
     #include <openssl/x509.h>

     X509_CINF *
     X509_CINF_new(void);

     void
     X509_CINF_free(X509_CINF *inf);

     X509_VAL *
     X509_VAL_new(void);

     void
     X509_VAL_free(X509_VAL *val);

     X509_CERT_AUX *
     X509_CERT_AUX_new(void);

     void
     X509_CERT_AUX_free(X509_CERT_AUX *aux);

DESCRIPTION
     X509_CINF_new() allocates and initializes an empty X509_CINF object,
     representing an ASN.1 TBSCertificate structure defined in RFC 5280
     section 4.1.  It is used inside the X509 object and holds the main
     information contained in the X.509 certificate including subject, public
     key, issuer, serial number, validity period, and extensions.
     X509_CINF_free() frees inf.

     X509_VAL_new() allocates and initializes an empty X509_VAL object,
     representing an ASN.1 Validity structure defined in RFC 5280 section 4.1.
     It is used inside the X509_CINF object and holds the validity period of
     the certificate.  X509_VAL_free() frees val.

     X509_CERT_AUX_new() allocates and initializes an empty X509_CERT_AUX
     structure.  It can be used inside an X509 object to hold optional non-
     standard auxiliary data appended to a certificate, for example friendly
     alias names and trust data.  X509_CERT_AUX_free() frees aux.

RETURN VALUES
     X509_CINF_new(), X509_VAL_new(), and X509_CERT_AUX_new() return the new
     X509_CINF, X509_VAL, or X509_CERT_AUX object, respectively, or NULL if an
     error occurs.
