PHP加密函数
<?php
$str = 'This is an example!';
echo '1:'.$str.'<br>';
$crypttostr = crypt($str);
echo '2:'.$crypttostr.'<br>';
?>
1:Thisisanexample! .
2:$1$WQ1.nK..$sYGDz2NVVKAPeQT3J1OKw/
F5刷新每次都不一样，因为密码随机，下面是固定密码
<?php
$str = 'This is an example!';
echo '1:'.$str.'<br>';
$crypttostr = crypt($str ,'ma');
echo '2:'.$crypttostr.'<br>';
?>
<?php
$str = 'Thisisanexample!';
echo '1:'.$str.'<br>';
$crypttostr = md5($str);
echo '2:'.$crypttostr.'<br>';
?>
1:Thisisanexample!
2:ef7e5805358cf0c1e8b5beab5b025d0e
<?php
$str = 'Thisisanexample!';
echo '1:'.$str.'<br>';
$crypttostr = sha1($str);
echo '2:'.$crypttostr.'<br>';
?>
1:Thisisanexample!

Mcrypt双向加密
获取算法和模式
<?php
$en_dir = mcrypt_list_algorithms();
echo 'Mcrypt Algorithm:';
foreach($en_dir as $en_value){
echo $en_value.",";
}
echo '<br>';
$en_mo = mcrypt_list_modes();
echo 'Mcrypt Modes:';
foreach($en_mo as $en_value){
echo $en_value.",";
}
?>
执行结果
McryptAlgorithm:
cast-128,gost,rijndael-128,twofish,cast-256,loki97,rijndael-192,saferplus,wake,blowfish-compat,des,rijndael-256,serpent,xtea,blowfish,enigma,rc2,tripledes,arcfour,
Mcrypt Modes:
cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream,
加解密（Mcrypt）：
<?php
$str = "JiaMiZhiQian";
$key = "111";
$cipher = MCRYPT_DES;
$modes = MCRYPT_MODE_ECB;
$iv = mcrypt_create_iv(mcrypt_get_iv_size($cipher ,$modes) ,MCRYPT_RAND);
echo 'JMQ:'.$str.'<br>';
$str_encrytp = mcrypt_encrypt($cipher,$key,$str ,$modes ,$iv);
echo 'JMH:'.$str_encrytp.'<br>';
$str_decrypt = mcrypt_decrypt($cipher,$key,$str_encrytp ,$modes ,$iv);
echo 'HY:'.$str_decrypt.'<br>';
?>
Mhash扩展库
<?php
$num = mhash_count();
echo 'Mhash Algorithm:<br>';
for($i = 0 ;$i < $num ;$i ++){
echo $i."=>".mhash_get_hash_name($i)." ";
}
?>
Mhash Algorithm:
0=>CRC32 1=>MD5 2=>SHA1 3=>HAVAL256 4=> 5=>RIPEMD160 6=> 7=>TIGER 8=>GOST 9=>CRC32B 10=>HAVAL224 11=>HAVAL192 12=>HAVAL160 13=>HAVAL128 14=>TIGER128 15=>TIGER160 16=>MD4 17=>SHA256 18=>ADLER32 19=>SHA224 20=>SHA512 21=>SHA384 22=>WHIRLPOOL 23=>RIPEMD128 24=>RIPEMD256 25=>RIPEMD320 26=> 27=>SNEFRU256 28=>MD2 29=>FNV132 30=>FNV1A32 31=>FNV164 32=>FNV1A64

$str_mhash = bin2hex(mhash($hash ,$str ,$key));
echo $str_mhash;
