Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and

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

SSH Chinese documentsSSH is a security protocol created on the application layer and transport layer, which is used to replace the poor security telnet and secure login.SSH is currently a more reliable protocol that provides security for Telnet

I. openvpn introduction openvpn is an SSL-based vpn. it uses the industrial standard SSL/TLS protocol to implement the Layer 2 and Layer 3 secure data link VPN. it has the following advantages: 1. based on the SSL protocol, security, and using a

Use require (' crypto ') to invoke the cryptographic module. The encryption module requires the support of the underlying system to provide OpenSSL. It provides a way to encapsulate security credentials and can be used for HTTPS secure networks and

It is important to understand the following for encryption and decryption:The two sides want to communicate, the middle connection may be bugged or even tampered with. The solution is to encrypt the contents of the transmission, using ciphertext to

The former concept of KeyStore is the place where the app is signed, and if you check Android KeyStore, the information is how to generate signatures for the app, but the meaning here is different. The Android KeyStore system allows you to store

1. SSL version Problems The credit for HTTPS encrypted transmission is TLS. SSL is the predecessor of TLS. The final version of SSL is 3.0, and the latest version of TLS is 1.3. The encryption function of TLS depends on the public/private key
