PKCS8_pkey_add1_attr(3)             OpenSSL            PKCS8_pkey_add1_attr(3)



NAME
       PKCS8_pkey_get0_attrs, PKCS8_pkey_add1_attr,
       PKCS8_pkey_add1_attr_by_NID, PKCS8_pkey_add1_attr_by_OBJ - PKCS8
       attribute functions

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/x509.h>

        const STACK_OF(X509_ATTRIBUTE) *
        PKCS8_pkey_get0_attrs(const PKCS8_PRIV_KEY_INFO *p8);
        int PKCS8_pkey_add1_attr(PKCS8_PRIV_KEY_INFO *p8, X509_ATTRIBUTE *attr);
        int PKCS8_pkey_add1_attr_by_NID(PKCS8_PRIV_KEY_INFO *p8, int nid, int type,
                                        const unsigned char *bytes, int len);
        int PKCS8_pkey_add1_attr_by_OBJ(PKCS8_PRIV_KEY_INFO *p8, const ASN1_OBJECT *obj,
                                       int type, const unsigned char *bytes, int len);

DESCRIPTION
       PKCS8_pkey_get0_attrs() returns a const STACK of X509_ATTRIBUTE present
       in the passed const PKCS8_PRIV_KEY_INFO structure p8.

       PKCS8_pkey_add1_attr() adds a constructed X509_ATTRIBUTE attr to the
       existing PKCS8_PRIV_KEY_INFO structure p8.

       PKCS8_pkey_add1_attr_by_NID() and PKCS8_pkey_add1_attr_by_OBJ()
       construct a new X509_ATTRIBUTE from the passed arguments and add it to
       the existing PKCS8_PRIV_KEY_INFO structure p8.

RETURN VALUES
       PKCS8_pkey_add1_attr(), PKCS8_pkey_add1_attr_by_NID(), and
       PKCS8_pkey_add1_attr_by_OBJ() return 1 for success and 0 for failure.

NOTES
       STACK of X509_ATTRIBUTE is present in many X509-related structures and
       some of them have the corresponding set of similar functions.
