Common hash encryption functions in php

Common hash encryption functions in php $ hash_list = hash_algos (); // return the registered hash rule list

Print_r ($ hash_list); // display the result

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 a string

Echo hash ('ripmd160 ', $ str); // Generate a hash value

$ Ctx = hash_init ('md5'); // initialize a hash value.

Hash_update ($ ctx, 'The quick brown Fox'); // injects data into the hash value

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

Echo hash_final ($ ctx); // output the final result

$ Str = "the quick brown fox jumped over the lazy dog."; // define a string

$ Fp = tmpfile (); // create a temporary file

Fwrite ($ fp, $ str); // write a string to a temporary file

Rewind ($ fp); // The position of the inverted file pointer

$ Ctx = hash_init ('md5'); // initialize a hash value.

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

Echo hash_final ($ ctx); // output the result

$ Str = "the quick brown fox jumped over the lazy dog."; // define a string

Echo hash_hmac ('ripmd160 ', $ str, 'secret'); // Generate the hash value containing the key

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

$ File = "example.txt"; // defines the file name.

$ Str = "the quick brown fox jumped over the lazy dog."; // define a 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'); // defines the string

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

Echo hash_final ($ ctx); // output the result
