AES 加密 PHP 和 JAVA 互通

PHP代码: <?phpclass Security {public static function encrypt($input, $key) {$size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);$input = Security::pkcs5_pad($input, $size);$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, '');$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);mcrypt_generic_init($td, $key, $iv);$data = mcrypt_generic($td, $input);mcrypt_generic_deinit($td);mcrypt_module_close($td);$data = base64_encode($data);return $data;} private static function pkcs5_pad ($text, $blocksize) {$pad = $blocksize - (strlen($text) % $blocksize);return $text . str_repeat(chr($pad), $pad);} public static function decrypt($sStr, $sKey) {$decrypted= mcrypt_decrypt(MCRYPT_RIJNDAEL_128,$sKey,base64_decode($sStr),MCRYPT_MODE_ECB); $dec_s = strlen($decrypted);$padding = ord($decrypted[$dec_s-1]);$decrypted = substr($decrypted, 0, -$padding);return $decrypted;}}   $key = "1234567891234567";$data = "example"; $value = Security::encrypt($data , $key );echo $value.'<br/>';echo Security::decrypt($value, $key ); ---------------java 代码   import javax.crypto.Cipher;import javax.crypto.spec.SecretKeySpec; import org.apache.commons.codec.binary.Base64; public class Security {public static String encrypt(String input, String key){byte[] crypted = null;try{SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES");Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");cipher.init(Cipher.ENCRYPT_MODE, skey);crypted = cipher.doFinal(input.getBytes());}catch(Exception e){System.out.println(e.toString());}return new String(Base64.encodeBase64(crypted));} public static String decrypt(String input, String key){byte[] output = null;try{SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES");Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");cipher.init(Cipher.DECRYPT_MODE, skey);output = cipher.doFinal(Base64.decodeBase64(input));}catch(Exception e){System.out.println(e.toString());}return new String(output);} public static void main(String[] args) {String key = "1234567891234567";String data = "example";System.out.println(Security.encrypt(data, key));System.out.println(Security.decrypt(Security.encrypt(data, key), key));}}
