ECDHE_RSA with P 256

At the time of writing this blog - Election week 2020, Confluent Cloud Shema Registry using Let's Encrypt to sign the certificates for Schema Registry (HTTPS endpoint), it uses TLS 1.2, ECDHE_RSA with P-256, and AES_256_GCM. And it's not working with SAP PO 7.5 latest SP 19. There is a list of default cipher suites, but it's not including the one above. For more information or those steps below not working, refer to this not ECDHE-RSA uses Diffie-Hellman on an elliptic curve group while DHE-RSA uses Diffie-Hellman on a modulo-prime group. What upsides has ECDHE-RSA over DHE-RSA? There is a well-known attack that works for conventional DH but not for ECDH. As a result to get the same level of assumed security* DH needs a much bigger group than ECDH. That means slower computations and more network traffic

ECDHE RSA is a method to exchange secret keys over an insecure channel in order to start encrypted communication. AES 256 GCM is an encryption (cipher) method , using the 256 bit key learned over the TLS 1.2 connection using ECDHE RSA. Advanced Encryption Standard with 256bit key in Cipher Block Chaining mode (AES 256 CBC) Cipher Block Chaining: In 2013, researchers demonstrated a timing attack against several TLS implementations using the CBC encryption algorithm (see isg.rhul.ac.uk ). Additionally, the CBC mode is vulnerable to plain-text attacks in TLS 1.0, SSL 3.0 and lower

ECDHE, the numbers correspond to the NIST P-256 curve (OpenSSL development version of OpenSSL; September 9, 2013, configured with 'enable-ec_nistp_64_gcc_128'). Note that the ECDHE+ECDSA combination provides 128 bits of security, and the other combinations pro-vide only 112 bits. For comparison, the rightmost (green) bar shows the performance of th The connection to this site is encrypted and authenticated using TLS 1.2, ECDHE_RSA with P-384, and AES_128_CBC with HMAC-SHA1. AES_128_CBC is obsolete. Enable an AES-GCM-based cipher suite. The server signature uses SHA-1, which is obsolete. Enable a SHA-2 signature algorithm instead. (Note this is different from the signature in the certificate.

Obsolete connection settings The connection to this site uses TLS 1.0 (an obsolete protocol), ECDHE_RSA with P-256 (a strong key exchange), and AES_256_CBC with HMAC-SHA1 (an obsolete cipher). Wie kann man das fixxen Using ECDHE-RSA-AES128-SHA cipher suite (with P-256 for example) is already a huge speed improvement over DHE-RSA-AES128-SHA thanks to the reduced size of the various parameters involved. Web browsers only support a handful of well-defined elliptic curves, chosen to ease an efficient implementation. Bodo Möller, Emilia Käsper and Adam Langley have provided 64-bit optimized versions of NIST P-224, P-256 and P-521 for OpenSSL. To get even more details on the matter, you can read. Looking at what Windows Server 2012 R2 actually supports on ciphers you'll find that it does not support CHACHA20_POLY1305 and that it supports GCM ciphers only with ECC certificates, i.e. it implements ciphers like TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256_P256 but not ciphers like TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 I get below error when I try to run that application, when I contacted the client they just asked to update JCE with 8 , I did below steps.

Same for Blockciphers (namely AES and Camellia, but only Camellia is just used by a few sites) in GCM or CCM mode (again, CCM is not used often, in fact I have never seen it outside of the specs)

TLS1-ECDHE-RSA-DES-CBC3-SHA TLS1-ECDHE-RSA-AES128-SHA TLS1-ECDHE-RSA-AES256-SHA. ECDHE ciphers should be configured along ECC curve P_256. To unbind and bind an ECC curve to an SSL virtual server, use the following commands: unbind ssl vserver <vServerName> -eccCurveName ALL bind ssl vserver <vServerName> -eccCurveName P_256. After performing the preceding steps and performing a security scan.
