Commonly used hash encryption functions in PHP

$hash _list=hash_algos (); Returns the list of registered hash rules

Print_r ($hash _list); Show results

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

Output hash Value information:

echo hash_file (' MD5 ', ' example.txt ');

$str = "The quick brown fox jumped over the lazy dog."; Defining strings

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

$ctx =hash_init (' MD5 '); Initialize a hash value

Hash_update ($ctx, ' The quick brown fox '); Pouring data into a hash value

Hash_update ($ctx, ' jumped over the lazy dog '); Pouring data into a hash value

echo hash_final ($CTX); Output the final result

$str = "The quick brown fox jumped over the lazy dog."; Defining strings

$FP =tmpfile (); Create a temporary file

Fwrite ($fp, $STR); Writes a string to a temporary file

Rewind ($FP); Rewind the position of the file pointer

$ctx =hash_init (' MD5 '); Initialize a hash value

Hash_update_stream ($ctx, $fp); Pouring data into the data stream

echo hash_final ($CTX); Output results

$str = "The quick brown fox jumped over the lazy dog."; Defining strings

echo Hash_hmac (' ripemd160 ', $str, ' secret '); Generate a hash value that contains the key

/* Create a file and write the string to it */

$file = "Example.txt"; Define file name

$str = "The quick brown fox jumped over the lazy dog."; Defining strings

File_put_contents ($file, $STR); Writing a string to a file

echo hash_hmac_file (' MD5 ', $file, ' secret '); Generate a hash value that contains the key

$ctx =hash_init (' SHA1 '); Defining strings

Hash_update ($ctx, ' The quick brown fox jumped over the the lazy Dog. '); Pouring data into the hash value

echo hash_final ($CTX); Output results
