It can hold a pointer to an .Vt X509_REQ_INFO object discussed below together with a cryptographic signature and information about the signature algorithm used. .Fn X509_REQ_free frees .Fa req . If .Fa req is a .Dv NULL pointer, no action occurs. .Pp .Fn X509_REQ_INFO_new allocates and initializes an empty .Vt X509_REQ_INFO object, representing an ASN.1 .Vt CertificationRequestInfo structure defined in RFC 2986 section 4.1. It is used inside the .Vt X509_REQ object and can hold the subject and the public key of the requested certificate and additional attributes. .Fn X509_REQ_INFO_free frees .Fa req_info . If .Fa req_info is a .Dv NULL pointer, no action occurs. .Sh RETURN VALUES .Fn X509_REQ_new and .Fn X509_REQ_INFO_new return the new .Vt X509_REQ or .Vt X509_REQ_INFO object, respectively, or .Dv NULL if an error occurs. .Sh SEE ALSO .Xr d2i_X509_REQ 3 , .Xr PEM_read_X509_REQ 3 , .Xr X509_new 3 , .Xr X509_REQ_check_private_key 3 , .Xr X509_REQ_digest 3 , .Xr X509_REQ_get0_signature 3 , .Xr X509_REQ_get_pubkey 3 , .Xr X509_REQ_get_subject_name 3 , .Xr X509_REQ_get_version 3 , .Xr X509_REQ_sign 3 .Sh STANDARDS RFC 2986: PKCS #10: Certification Request Syntax Specification .Sh HISTORY .Fn X509_REQ_new , .Fn X509_REQ_free , .Fn X509_REQ_INFO_new , and .Fn X509_REQ_INFO_free first appeared in SSLeay 0.4.4 and have been available since .Ox 2.4 .
