Subject: [PATCH] winpr/ssl: Load legacy provider when initializing OpenSSL 3.0
|
|
|
4cd190 |
|
|
|
4cd190 |
With OpenSSL 3.O, FreeRDP log contains errors like:
|
|
|
4cd190 |
|
|
|
4cd190 |
```
|
|
|
4cd190 |
4036740A4C7F0000:error:0308010C:digital envelope routines:
|
|
|
4cd190 |
inner_evp_generic_fetch:unsupported:crypto/evp/evp_fetch.c:346:
|
|
|
4cd190 |
Global default library context, Algorithm (MD4 : 85), Properties ()
|
|
|
4cd190 |
```
|
|
|
4cd190 |
|
|
|
4cd190 |
This leads to connection failures in some cases. This is because algorithms
|
|
|
4cd190 |
like MD4 are now part of the legacy provider, which is not loaded by
|
|
|
4cd190 |
default. Let's explicitly load that provider. With this change, also the
|
|
|
4cd190 |
other provides has to be explicitely loaded.
