Wallets are used on public chains such as Bitcoin/Ethereum. Wallets are primarily used to manage the user's private key, and the user's digital currency on the chain, which is the signature of the transaction with the private key. The private key

The DH key exchange of SSH is a set of key exchange algorithms for several complex algorithms. The algorithm called Diffie-hellman-groupx-exchange-shax in RFC4419 (there is another simple Rsax-shax switching algorithm). This paper takes
