| 7 | =head1 DESCRIPTION
|
|---|
| 8 |
|
|---|
| 9 | The EVP_KDF-X942-CONCAT algorithm is identical to EVP_KDF-X963. It is
|
|---|
| 10 | used for key agreement to derive a key using input such as a shared secret key
|
|---|
| 11 | and shared info.

|
|---|
| 15 | "X942KDF_CONCAT" is the name for this implementation; it
|
|---|
| 16 | can be used with the EVP_KDF_fetch() function.
