Commonly used hash encryption functions in php

$hash_list=hash_algos(); //Return the registered hash rule list

print_r($hash_list); //Display the results

Create a file to calculate the hash value: file_put_contents('example.txt', 'the quick brown fox jumped over the lazy dog.');

Output hash value information:

echo hash_file('md5', 'example.txt');

$str="the quick brown fox jumped over the lazy dog."; //Define string

echo hash('ripemd160',$str); //Generate hash value

$ctx=hash_init('md5'); //Initialize a hash value

hash_update($ctx,'the quick brown fox'); //Pour data into the hash value

hash_update($ctx,'jumped over the lazy dog.'); //Pour data into the hash value

echo hash_final ($ctx);                   // Output the final result

 

$str="the quick brown fox jumped over the lazy dog.";         // Define the string

$fp=tmpfile();                               File ifwrite ($ FP, $ STR); // Write the string into temporary files

rewind ($ fp); // back to the position of the file pointer

$ ctx = hash_init ('md5'); //Initialize a hash value

hash_update_stream($ctx,$fp); brown fox jumped over the lazy dog."; //Define string

echo hash_hmac('ripemd160',$str,'secret'); //Generate a hash value containing the key

/*Create a file And write the string into it */

$file="example.txt"; //Define the file name

$str=" the quick brown fox jumped over the lazy dog."; //Define the string

file_put_contents($file,$str); //Write a string to the file

echo hash_hmac_file('md5',$file,'secret'); //Generate a hash value containing the key

$ ctx=hash_init('sha1'); //Define the string

hash_update($ctx,'the quick brown fox jumped over the lazy dog.'); //Pour data into the hash value

echo hash_final($ ctx); //Output results
