/*

* `rsa_pss_rsae_*` MUST BE PUT ARTER `rsa_pkcs1_*` before below compitable fixed
|
||||
* The compitable issue is When
|
||||
* - GnuTLS/OpenSSL is configured as tls12 server with rsa key
|
||||
* - `mebedTLS` is configured as hybrid mode.
|
||||
* - The order is `rsa_pss_rsae_*`, `rsa_pkcs1_*`.
|
||||
* GnuTLS/OpenSSL will return `rsa_pss_rsae_*` which are not supported by
|
||||
* TLS 1.2 in mbedTLS.
|
||||
* When GnuTLS/Openssl server is configured in TLS 1.2 mode with a certificate
|
||||
* declaring an RSA public key and Mbed TLS is configured in hybrid mode, if
|
||||
* `rsa_pss_rsae_*` algorithms are before `rsa_pkcs1_*` ones in this list then
|
||||
* the GnuTLS/Openssl server chooses an `rsa_pss_rsae_*` signature algorithm
|
||||
* for its signature in the key exchange message and as Mbed TLS 1.2 does not
|
||||
* support them, the handshake fails.
