The encryption and decryption function in PHP and the example usage of DES encryption and decryption
This article introduces the knowledge of "the encryption and decryption function in PHP and the example usage of DES encryption and decryption". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
This paper gives an example of the application of encryption and decryption function in PHP and DES encryption and decryption, which is shared for your reference. The details are as follows:
Example, example of php encryption and decryption
Encryption function:
The copy code is as follows:
/ *
* function: encrypt strings
* Parameter 1: content to be encrypted
* Parameter 2: key
, /
Function passport_encrypt ($str,$key) {/ / encryption function
Srand ((double) microtime () * 1000000)
$encrypt_key=md5 (rand (0, 32000))
$ctr=0
$tmp=''
For ($iSuppli
The following are the test results:
The copy code is as follows:
$str = '12345678'
$key = '1234abcd'
$crypt = new DES ($key)
$mstr = $crypt- > encrypt ($str)
$str = $crypt- > decrypt ($mstr)
Echo $str.''. $mstr
Example 2
The code is as follows:
The copy code is as follows:
/ * *
* encrypt the parameters that need to be passed in url by get
, /
Function args_encode ($data) {
If (is_array ($data)) {
$string = http_build_query ($data)
Return base64_encode ($string)
} else {
Return false
}
}
/ * *
* get the parameters passed by get in url
, /
Function getargs () {
$string = base64_decode ($_ GET ['args'])
Parse_str ($string,$g)
Return $g
}
