Des decryption, but key is 36 bytes, how to handle?

And the Java side of the docking, I use PHP decryption, key is 36 bytes, so there is no clue. I wonder if there's a generic way to convert these 36 bytes into 16 or 32 bytes? Thank you all first.

Here is the code snippet for Java:

public static String DES_KEY="36位的key";

Execution method:

DesUtil.decrypt(rs.getString(i+1),Global.DES_KEY );

Class:

    public class Desutil {private final static String des = "des";             Private final static String padding= "Des/ecb/pkcs5padding";             Private final static Log log= logfactory.getlog (desutil.class); public static byte[] Encrypt (byte[] src, byte[] key) throws Exception {securerandom sr = new Secureran                    Dom ();                     Deskeyspec DKs = new Deskeyspec (key);                     Secretkeyfactory keyfactory = secretkeyfactory.getinstance (DES);                     Secretkey SecureKey = Keyfactory.generatesecret (DKS);                     Cipher Cipher = cipher.getinstance (PADDING);                     Cipher.init (Cipher.encrypt_mode, SecureKey, SR);                  return cipher.dofinal (SRC); } public static byte[] Decrypt (byte[] src, byte[] key) throws Exception {SecureRandom s                     R = new SecureRandom ();             Deskeyspec DKs = new Deskeyspec (key);       Secretkeyfactory keyfactory = secretkeyfactory.getinstance (DES);                     Secretkey SecureKey = Keyfactory.generatesecret (DKS);                     Cipher Cipher = cipher.getinstance (PADDING);                   Cipher.init (Cipher.decrypt_mode, SecureKey, SR);                  return cipher.dofinal (SRC);                           Public final static string decrypt (string data,string key) {try {                 return new String (Decrypt (Base64.decode (Data.getbytes ()), key.getbytes ());                       }catch (Exception e) {log.error ("Exception-->desutil");                 E.printstacktrace ();               } return null;                           Public final static string decrypt (string data,string key, String charset) {try { return new String (Decrypt (Base64.decode (Data.getbytes ()), Key.getbyTES ()), CharSet);                          }catch (Exception e) {log.error ("Exception-->desutil");                 E.printstacktrace ();               } return null;  Public final static string encrypt (String code,string key) {try {return                 Base64.encodebytes (Encrypt (code.getbytes ("Utf-8"), Key.getbytes ());                          }catch (Exception e) {log.error ("Exception-->desutil");                 E.printstacktrace ();               } return null; }/* public static void Main (string[] args) {/** * Convert byte[] String * * @param sr c * @return */public static String bytesto16hexstring (byte[] src) {stringbuild                   Er stringBuilder = new StringBuilder (""); if (src = = NULL | | src.length <= 0) {REturn "";                            } for (int i = 0; i < src.length; i++) {int v = src[i] & 0xFF;                            String HV = integer.tohexstring (v);                            if (Hv.length () < 2) {stringbuilder.append (0);                   } stringbuilder.append (HV);         } return stringbuilder.tostring (); }}

Complete up to 48 bytes with redundant characters.
