sha算法 哈希算法_SHA1哈希算法教程及其用法示例
sha算法 哈希算法
SHA1 is a hash algorithm that is created by the National Security Agency (NSA). SHA1 hash algorithm is generally used in security and data integrity applications. SHA-1 is created in 1995 as the successor of the SHA-0. Both SHA1 and SHA-1 refer to each other.
SHA1是由國家安全局(NSA)創建的哈希算法。 SHA1哈希算法通常用于安全性和數據完整性應用程序中。 SHA-1于1995年創建，是SHA-0的后繼產品。 SHA1和SHA-1互相引用。
安全哈希算法1或SHA1 (Secure Hash Algorithm 1 or SHA1)
SHA1 is in a hash or message digest algorithm where it generates 160-bit unique value from the input data. The input data size doesn’t matter as SHA1 always generates the same size message digest or hash which is 160 bit. This can be seen very confusing but the algorithm is designed for this.
SHA1在散列或消息摘要算法中，在其中它從輸入數據生成160位唯一值。 輸入數據的大小無關緊要，因為SHA1總是生成相同大小的消息摘要或160位的哈希值。 可以看出這很令人困惑，但是算法是為此目的而設計的。
SHA1不再安全 (SHA1 Is Not Secure Anymore)
SHA1 is used for data integrity and security. Especially after 2005, there are a lot of different attacks against the SHA1 algorithm to prevent it is not secure. The first public collusion published in 2017 where SHA1 is not considered secure after that time. Currently, SHA2 family algorithms are invented to be used for security. A collision attack is simply a different input value that can generate the same output hash value which will fake the security systems.
SHA1用于數據完整性和安全性。 特別是在2005年之后，針對SHA1算法的安全性有很多不同的攻擊，以防止它不安全。 2017年發布了第一個公共合謀，在那之后SHA1被認為不安全。 當前，發明了SHA2系列算法以用于安全性。 沖突攻擊只是一個不同的輸入值，它可以生成相同的輸出哈希值，這將偽造安全系統。
SHA1工具 (SHA1 Tools)
Currently, there are a lot of tools where some of them online to create SHA1 hash values. In the following address, there is a tool which supports a lot of different type of hash and encoding algorithms.

Linux SHA1使用 (Linux SHA1 Usage)
Linux distributions like Ubuntu, Debian, Mint, Kali, Fedora, and CentOS provide sha1sum command which can calculate the SHA1 sum of the given file.
Linux發行版(例如Ubuntu，Debian，Mint，Kali，Fedora和CentOS)提供了sha1sum命令，該命令可以計算給定文件的SHA1和。
$ sha1sum password.txtPHP SHA1的用法 (PHP SHA1 Usage)
PHP programming language provides a SHA1 calculation function named sha1() as builtin. We just need to provide the data or text we can to calculate its hash. In this example, we will calculate the hash of the “crackme123”.
PHP編程語言提供了一個內置的名為sha1()的SHA1計算功能。 我們只需要提供可以計算其哈希值的數據或文本即可。 在此示例中，我們將計算“ crackme123”的哈希。
$str="crackme123";$str_hash = sha1($str);echo $str_hash; PHP SHA1 UsagePHP SHA1的用法Python SHA1用法(Python SHA1 Usage)
Python also provides the SHA1 hash algorithm support with the hashlib module/library. We will first import hashlib and then use the sha1() function by providing the data or text we want to calculate the hash. In this example, we will calculate the hash of “crackme”.
Python還為hashlib模塊/庫提供SHA1哈希算法支持。 我們將首先導入hashlib，然后通過提供我們要計算哈希的數據或文本來使用sha1()函數。 在此示例中，我們將計算“ crackme”的哈希。
import hashlibstr="crackme"str_hash=hashlib.sha1(str.encode())print(str_hash)print(str_hash.hexdigest()) Python SHA1 UsagePython SHA1用法SHA1和MD5(SHA1 vs MD5)
MD5 is another popular hash algorithm that is created before the SHA1. But they are used in the 1990s and 2000s and were an alternative for each other. In this part, we will compare the SHA1 and MD5 hash algorithms.
MD5是在SHA1之前創建的另一種流行的哈希算法。 但是它們分別在1990年代和2000年代使用，并且彼此替代。 在這一部分中，我們將比較SHA1和MD5哈希算法。
- `Speed`: MD5 has fewer complex algorithms which make it faster than SHA1 速度：MD5的復雜算法更少，比SHA1更快
- `Security`: SHA1 has a more complex algorithm which makes is more secure than MD5.安全性：SHA1具有更復雜的算法，因此比MD5更安全。
- `Name`: SHA1 stands for `Secure Hash Algorithm` where MD5 stands for `Message Digest`. 名稱：SHA1代表安全哈希算法，其中MD5代表消息摘要。
- `Hash Size`: SHA1 creates a 160-bit long hash/message digest where MD5 creates a 128-bit hash/message digest. 散列大小：SHA1創建一個160位長的散列/消息摘要，其中MD5創建一個128位散列/消息摘要。
- `Popularity`: MD5 was more popular then SHA1 but in the last decade it losing its popularity 人氣：MD5比SHA1更為流行，但在最近十年中，它失去了流行性
- `Usage Cases`: MD5 is generally used in hardware restricted devices like a switch, router where SHA1 is used in more stronger devices like computers.使用案例：MD5通常用于受硬件限制的設備(如交換機，路由器)中，而SHA1用于更強大的設備(如計算機)中。
