Among the methods used for key exchange/agreement are: public and private keys generated with RSA (denoted TLS_RSA in the TLS handshake protocol), Diffie–Hellman (TLS_DH), ephemeral Diffie–Hellman (TLS_DHE), elliptic-curve Diffie–Hellman (TLS_ECDH), ephemeral elliptic-curve Diffie–Hellman (TLS_ECDHE), anonymous Diffie–Hellman (TLS_DH_anon), pre-shared key (TLS_PSK) and Secure …

Configure Oracle's JDK and JRE Cryptographic Algorithms Change default key size of the AlgorithmParameterGenerator and KeyPairGenerator implementations from 1024 to 2048 bits This change will update the JDK providers to use 2048 bits as the default key size for DSA, RSA, and DiffieHellman instead of 1024 bits when applications have not explicitly initialized the and objects ECC vs RSA: Comparing SSL/TLS Algorithms - Cheap SSL Security Dec 06, 2019 Disabling select TLS 1.2 ciphers

TLS defines the protocol that this cipher suite is for; it will usually be TLS. ECDHE_RSA indicates the key exchange algorithm being used. The key exchange algorithm is used to determine if and how the client and server will authenticate during the handshake.

Disabling select TLS 1.2 ciphers

TLS (Transport Layer Security) is a cryptographic protocol used to secure network communications.When hardening system security settings by configuring preferred key-exchange protocols, authentication methods, and encryption algorithms, it is necessary to bear in mind that the broader the range of supported clients, the lower the resulting security.

authentication - TLS-RSA vs TLS-ECDHE-RSA vs static DH In the "server key exchange" packet for TLS-ECDHE-RSA, there is a DH key with RSA signature. The RSA signature for the "dh key" and "certificate" is used for authentication purposes / digital signature for the server to prove it is who it claims to be. "RSA public key" in the certificate, for TLS-RSA, is used by the client to encrypt the PMS. Disabling TLSv1.0 protocol and 3DES cipher suite for May 17, 2019 What is the Windows default cipher suite order? - Nartac Every version of Windows has a different cipher suite order. Depending on what Windows Updates the server has applied, the order can be different even with the same version of Windows.
