nonce

In the "Hbase-0.98.6 source analysis--put Writing client end Process" This article, we introduced the put write operation in the client side of the operation process, in the introduction of the Submit () method, there is a strange noun--nonce mechanism, Today, we will introduce the indispensable management mechanism of the nonce. HBase has a very strong fault-tolerant characteristics, and in the network wor

Brief introduction The nonce value exists primarily because it is account-based and differs from the Utxo-based bitcoin. Nonce values are primarily used to prevent replay attacks. An external account is sent a nonce plus one per transaction. Each contract account creates a nonce plus one. The value of the

Digest access authenticationHttps://en.wikipedia.org/wiki/Digest_access_authentication Digest access authentication is one of the Agreed-upon methods a Web server can use to negotiate credentials, suc H as username or password, with a user ' s web browser. This can is used to confirm the identity of a user before sending sensitive information, such as online banking transactio N history. It applies a hash function to the username and password before sending them over the Network. In con
