# 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

# 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.
