一、oracle中的加密函数encrypt_des

create or replace function encrypt_des(vi_data varchar2) return varchar2 is

--加密

vr_data varchar2(4000);

vr_enc varchar2(4000);

raw_input RAW(128);

key_input RAW(128);

decrypted_raw RAW(2048);

vr_key varchar2(64);

begin

if vi_data is null then

return null;

end if;

select MOBILEKEY

into vr_key

from CENKEY;

vr_data := rpad(vi_data, (trunc(length(vi_data) / 8) + 1) * 8, chr(0));

raw_input := UTL_RAW.CAST_TO_RAW(vr_data);

key_input := UTL_RAW.CAST_TO_RAW(vr_key);

dbms_obfuscation_toolkit.DESEncrypt(input => raw_input, key => key_input,

encrypted_data => decrypted_raw);

vr_enc := rawtohex(decrypted_raw);

dbms_output.put_line(vr_enc);

return vr_enc;

end;

下图是加密后的结果

将18693157906加密后的密文是 FAD42A3BB2A4B9A5B36847714A56FE65

二、java中对应的加密、解密方法

public class Utils {

#密钥

private static String key = "test#5&124*!de";

/**

* 加密

* @param inStr

* @return

*/

public static String ENCRYPT_DES(String inStr) {

DESKeySpec desKey;

SecretKey securekey;

Cipher cipher;

try {

desKey = new DESKeySpec(key.getBytes());

securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);

cipher = Cipher.getInstance("DES/CBC/NoPadding");

cipher.init(Cipher.ENCRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));

byte[] inBytes = new byte[((int) (inStr.length() / 8) + 1) * 8];

for (int i = 0; i < inStr.length(); i++) {

inBytes[i] = inStr.getBytes()[i];

}

byte[] enBytes = cipher.doFinal(inBytes);

String hexStr = DatatypeConverter.printHexBinary(enBytes);

return hexStr;

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return null;

}

/**

* 解密

* @param encryptStr

* @return

*/

public static String DECRYPT_DES(String encryptStr) {

DESKeySpec desKey;

SecretKey securekey;

Cipher cipher;

try {

desKey = new DESKeySpec(key.getBytes());

securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);

cipher = Cipher.getInstance("DES/CBC/NoPadding");

cipher.init(Cipher.DECRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));

byte[] decryptBytes = cipher.doFinal(Hex.decodeHex(encryptStr.toCharArray()));

return new String(decryptBytes).trim();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return null;

}

public static void main(String[] args) {

System.out.println("加密："+ENCRYPT_DES("18693157906"));

System.out.println("解密："+DECRYPT_DES("FAD42A3BB2A4B9A5B36847714A56FE65"));

}

}

三、运行代码得到结果

可以看到加密后的密文是FAD42A3BB2A4B9A5B36847714A56FE65

解密后的明文是18693157906

跟数据库加密一致
