| 19 | =head1 DESCRIPTION
|
|---|
| 20 |
|
|---|
| 21 | PKCS8_pkey_get0_attrs() returns a const STACK of X509_ATTRIBUTE present in
|
|---|
| 22 | the passed const PKCS8_PRIV_KEY_INFO structure B<p8>.
|
|---|
| 23 |
|
|---|
| 24 | PKCS8_pkey_add1_attr() adds a constructed X509_ATTRIBUTE B<attr> to the
|
|---|
| 25 | existing PKCS8_PRIV_KEY_INFO structure B<p8>.
|
|---|
| 26 |
|
|---|
| 27 | PKCS8_pkey_add1_attr_by_NID() and PKCS8_pkey_add1_attr_by_OBJ() construct a new
|
|---|
| 28 | X509_ATTRIBUTE from the passed arguments and add it to the existing
|
|---|
| 29 | PKCS8_PRIV_KEY_INFO structure B<p8>.
|
|---|
| 30 |
|
|---|
| 31 | =head1 RETURN VALUES
|
|---|
| 32 |
|
|---|
| 33 | PKCS8_pkey_add1_attr(), PKCS8_pkey_add1_attr_by_NID(), and
|
|---|
| 34 | PKCS8_pkey_add1_attr_by_OBJ() return 1 for success and 0 for failure.
|
|---|
| 35 |
|
|---|
| 36 | =head1 NOTES
|
|---|
| 37 |
|
|---|
| 38 | STACK of X509_ATTRIBUTE is present in many X509-related structures and some of
|
|---|
| 39 | them have the corresponding set of similar functions.
