Evaluate the compatibility with the des encryption and decryption functions or classes of PHP5.5 and 5.6

 Key = $ key; if ($ iv = 0) {$ this-> iv = $ key;} else {$ this-> iv = $ iv; // mcrypt_create_iv (encrypt (MCRYPT_DES, decrypt), MCRYPT_DEV_RANDOM) ;}} function encrypt ($ str) {// encrypted, returns an uppercase hexadecimal string $ size = encrypt (MCRYPT_DES, MCRYPT_MODE_CBC); $ str = $ this-> pkcs5Pad ($ str, $ size); return strtoupper (bin2hex (mcrypt_cbc (MCRYPT_DES, $ this-> key, $ str, MCRYPT_ENCRYPT, $ This-> iv);} function decrypt ($ str) {// decrypt $ strBin = $ this-> hex2bin (strtolower ($ str )); $ str = mcrypt_cbc (MCRYPT_DES, $ this-> key, $ strBin, MCRYPT_DECRYPT, $ this-> iv); $ str = $ this-> pkcs5Unpad ($ str ); return $ str;} function hex2bin ($ hexData) {$ binData = ""; for ($ I = 0; $ I <strlen ($ hexData); $ I + = 2) {$ binData. = chr (hexdec (substr ($ hexData, $ I, 2);} return $ binData ;} Function pkcs5Pad ($ text, $ blocksize) {$ pad = $ blocksize-(strlen ($ text) % $ blocksize); return $ text. str_repeat (chr ($ pad), $ pad);} function pkcs5Unpad ($ text) {$ pad = ord ($ text {strlen ($ text)-1 }); if ($ pad> strlen ($ text) return false; if (strspn ($ text, chr ($ pad), strlen ($ text)-$ pad )! = $ Pad) return false; return substr ($ text, 0,-1 * $ pad) ;}$ my_encrypt = new DES ('qwertyuiop '); echo $ my_encrypt-> encrypt ('20140901 ');

None of the above found on the Internet is correct. it seems that there are also various errors in testing due to the PHP version. I don't know how to change it.

Php5.6.3 passed
It is said to be compatible with java

Your Deprecated: Function mcrypt_cbc () is deprecated
Obviously, it cannot be used.
