| 17 | =head1 DESCRIPTION
|
|---|
| 18 |
|
|---|
| 19 | EVP_PKEY2PKCS8() converts a private key I<pkey> into a returned PKCS8 object.
|
|---|
| 20 |
|
|---|
| 21 | EVP_PKCS82PKEY_ex() converts a PKCS8 object I<p8> into a returned private key.
|
|---|
| 22 | It uses I<libctx> and I<propq> when fetching algorithms.
|
|---|
| 23 |
|
|---|
| 24 | EVP_PKCS82PKEY() is similiar to EVP_PKCS82PKEY_ex() but uses default values of
|
|---|
| 25 | NULL for the I<libctx> and I<propq>.
|
|---|
| 26 |
|
|---|
| 27 | =head1 RETURN VALUES
|
|---|
| 28 |
|
|---|
| 29 | EVP_PKEY2PKCS8() returns a PKCS8 object on success.
|
|---|
| 30 | EVP_PKCS82PKEY() and EVP_PKCS82PKEY_ex() return a private key on success.
|
|---|
| 31 |
|
|---|
| 32 | All functions return NULL if the operation fails.
