WebDiffie-Hellman Algorithm in Java. Diffie-Hellman algorithm is one of the most important algorithms used for establishing a shared secret. At the time of exchanging data over a public network, we can use the shared secret for secret communication. We use an elliptic curve for generating points and getting a secret key using the parameters. WebDiffie-Hellman Standards []. There are a number of standards relevant to Diffie-Hellman key agreement. Some of the key ones are: PKCS 3 defines the basic algorithm and data formats to be used.; ANSI X9.42 is a later standard than PKCS 3 and provides further guidance on its use (note OpenSSL does not support ANSI X9.42 in the released …
