Kā pārvērst stringu uz byteArray?

[fjckls]

Man ir jāatrisina šāds te:

Before calculating the MD5 hash, string should most likely be converted to a byte array: when doing so, it should be treated as 7-bit ASCII. After calculating the MD5 hash, the resulting byte array containing the hash is base-64 encoded.

For example:

BASE64(MD5(TEST1234|MM00402320|MDB@INTERMEZZOGROUP.COM|PREVIEW)) = zqdmWws60Bq80I2RFkgW1Q==

 

Izmeklējos un netieku gudrs kā iespējams "string should most likely be converted to a byte array",

Pagaidu kods, kas nestrādā:

 

<?php

$one = "TEST1234";
$two = "MM00402320";
$three = "MDB@INTERMEZZOGROUP.COM";
$four = "PREVIEW))";
$strng = $one . "|" . $two . "|" . $three . "|" . $four;

$hash = base64_encode(md5($strng));

echo $hash;
// NjNhZjFmN2NmMGY1NjU0NjE1MmZlMTIyMzRkZjdkMGY= bet jaabuut zqdmWws60Bq80I2RFkgW1Q==
?>

 

Hmm.. kādas idejas?

PAldies!

Hmm, man liekas, ka tas nav iespejams.

md5 atgriež 32 simbolus, base64 overheads ir ~33% Nav iespējams iegūt īsāku virkni par to, kas tiek dota.

1) $four ir jābūt bez ))

2) md5($str, true);

string md5 ( string $str [, bool $raw_output = false ] )
