Hello,
I'm trying to force grpc (C++) to use only TLS 1.3 ciphers via the
environment variable:
export GRPC_SSL_CIPHER_SUITES=TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256
However, when I try to run the grpc server it errors out:
E1210 14:02:58.379895519 2232804 ssl_transport_security.cc:828] Invalid
cipher list: TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256.
E1210 14:02:58.379963852 2232804 ssl_security_connector.cc:268] Handshaker
factory creation failed with TSI_INVALID_ARGUMENT.
E1210 14:02:58.380010816 2232804 server_secure_chttp2.cc:124]
{"created":"@1639173778.379988900","description":"Unable to create secure
server with credentials of type
Ssl","file":"_deps/grpc-src/src/core/ext/transport/chttp2/server/secure/server_secure_chttp2.cc","file_line":104}
Is there anything specific I need to set when generating my TLS
certificates?
