Secure programming with the OpenSSL API First, Concept: 1. What is SSL.   SSL is an abbreviation, the full name is Secure Sockets Layer.   It is the standard that supports secure communication over the Internet and integrates data cryptography into

1 overview The time efficiency of the list lookup is O (N), and the log2n,b+ tree is log2n by the binary method, but the time efficiency of searching the hash list is O (1). Design efficient algorithms often need to use the hash list, the constant

BrieflyOpenSSL is a strong Secure Sockets Layer cipher library that includes key cryptographic algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides a rich set of applications for testing or other

OpenSSL encoding rules1. data encoding format Openssl data encoding rules are based on ans.1. What is ans.1? An Explanation on top of the project ASN.1 (Abstract Syntax Notation One) is a structured Description Language, which consists of two parts:

Prevent man-in-the-middle (mitm) Attacks Document options

  Hash function: an irreversible function. Its input can be a byte stream of any length. Its output is of a fixed size. The hash function is used to generate a digest for your file. It is unique. For example, y = f (x) x indicates that input y

The most frequently used data types in PHP are non-strings and arrays. PHP is easier to use and also benefits from the flexible array types. It is necessary to introduce the hash table (HashTable) before giving a detailed introduction to these data

Php kernel parsing: hash table in PHP. The most frequently used data types in PHP are non-strings and arrays. PHP is easier to use and also benefits from the flexible array types. Before getting a detailed description of these data types, PHP must
