Bugfix
|
||||
* Support re-assembly of fragmented handshake messages in TLS (both
|
||||
1.2 and 1.3). The lack of support was causing handshake failures with
|
||||
some servers, especially with TLS 1.3 in practice. There are a few
|
||||
limitations, notably a fragmented ClientHello is only supported when
|
||||
TLS 1.3 support is enabled. See the documentation of
|
||||
mbedtls_ssl_handshake() for details.
