X509_REQ_ADD_EXTENSIONS(3) FreeBSD Library Functions Manual NAME X509_REQ_add_extensions, X509_REQ_add_extensions_nid, X509_REQ_get_extensions, X509_REQ_extension_nid - extensions in certification requests SYNOPSIS #include <openssl/x509.h> int X509_REQ_add_extensions(X509_REQ *req, STACK_OF(X509_EXTENSION) *extensions); int X509_REQ_add_extensions_nid(X509_REQ *req, STACK_OF(X509_EXTENSION) *extensions, int nid); STACK_OF(X509_EXTENSION) * X509_REQ_get_extensions(X509_REQ *req); int X509_REQ_extension_nid(int nid); DESCRIPTION X509_REQ_add_extensions() encodes the array of extensions using i2d_X509_EXTENSIONS(3) and adds a new X.501 Attribute object of the type NID_ext_req to req using the equivalent of X509_ATTRIBUTE_create_by_NID(3) with a type of V_ASN1_SEQUENCE. X509_REQ_add_extensions_nid() is identical except that the specified nid is used as the X.501 Attribute type instead of NID_ext_req. X509_REQ_get_extensions() retrieves the first value of the first X.501 Attribute of appropriate type. By default, the attribute types NID_ext_req and NID_ms_ext_req are considered appropriate. X509_REQ_extension_nid() checks whether X509_REQ_get_extensions() regards the nid argument as a type appropriate for storing extensions. RETURN VALUES X509_REQ_add_extensions() and X509_REQ_add_extensions_nid() returns 1 for success or 0 for failure. X509_REQ_get_extensions() returns a newly allocated array of ASN.1 Extension objects or NULL if req is NULL, does not contain CertificationRequestInfo, contains no attribute of an appropriate type, or if decoding or memory allocation fails. X509_REQ_extension_nid() returns 1 if nid is considered appropriate or 0 otherwise.
