| 13 | The following algorithms are available in the FIPS provider as well as the
|
|---|
| 14 | default provider:
|
|---|
| 15 |
|

| 16 | =over 4
|
|---|
| 17 |
|
|---|
| 18 | =item "DES-EDE3-ECB" or "DES-EDE3"
|

|
|---|
| 21 |
|

| 22 | =back
|
|---|
| 23 |
|
|---|
| 24 | The following algorithms are available in the default provider, but not the
|
|---|
| 25 | FIPS provider:
