X509_REQ_NEW(3) FreeBSD Library Functions Manual X509_REQ_NEW(3) NAME X509_REQ_new, X509_REQ_dup, X509_to_X509_REQ, X509_REQ_free, X509_REQ_INFO_new, X509_REQ_INFO_free - PKCS#10 certification requests SYNOPSIS #include <openssl/x509.h> X509_REQ * X509_REQ_new(void); X509_REQ * X509_REQ_dup(X509_REQ *req); X509_REQ * X509_to_X509_REQ(X509 *x, EVP_PKEY *pkey, const EVP_MD *md); void X509_REQ_free(X509_REQ *req); X509_REQ_INFO * X509_REQ_INFO_new(void); void X509_REQ_INFO_free(X509_REQ_INFO *req_info); DESCRIPTION X509_REQ_new() allocates and initializes an empty X509_REQ object, representing an ASN.1 CertificationRequest structure defined in RFC 2986 section 4.2. It can hold a pointer to an X509_REQ_INFO object discussed below together with a cryptographic signature and information about the signature algorithm used. X509_REQ_dup() creates a deep copy of req using ASN1_item_dup(3), setting the reference count of the copy to 1. X509_to_X509_REQ() allocates a new certification request object, copies the subject name and the public key into it from the certificate x, and sets the version to zero. Unless pkey is NULL, it also signs the request with X509_REQ_sign(3) using pkey and md. X509_REQ_free() frees req. If req is a NULL pointer, no action occurs. X509_REQ_INFO_new() allocates and initializes an empty X509_REQ_INFO object, representing an ASN.1 CertificationRequestInfo structure defined in RFC 2986 section 4.1. It is used inside the X509_REQ object and can hold the subject and the public key of the requested certificate and additional attributes. X509_REQ_INFO_free() frees req_info. If req_info is a NULL pointer, no action occurs. RETURN VALUES X509_REQ_new(), X509_REQ_dup(), X509_to_X509_REQ(), and X509_REQ_INFO_new() return the new X509_REQ or X509_REQ_INFO object, respectively, or NULL if an error occurs.
