kettle-使用 java 脚本 对某个字段进行 AES 解密

 

 kettle 加解密 java 脚本

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import com.sun.jersey.core.util.Base64;
import java.io.UnsupportedEncodingException;


import java.util.*;
public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException {
  if (first) {
    first = false;

  }

  Object[] r = getRow();

  if (r == null) {
    setOutputDone();
    return false;
  }
    r = createOutputRow(r, data.outputRowMeta.size());
  //解密 NAME
    String sSrc_NAME = get(Fields.In, "NAME").getString(r);
	String dSrc_NAME = decrypt(sSrc_NAME);
 	get(Fields.Out, "NAME").setValue(r, dSrc_NAME);
	
  //解密 PHONE
    String sSrc_PHONE = get(Fields.In, "PHONE").getString(r);
	String dSrc_PHONE = decrypt(sSrc_PHONE);
 	get(Fields.Out, "PHONE").setValue(r, dSrc_PHONE);
	

	putRow(data.outputRowMeta, r);
    return true;

}


public static String decrypt(String sSrc) {

	try {
		SecretKeySpec skeySpec = new SecretKeySpec("AEA密钥".getBytes("UTF-8"), "AES");
		Cipher cipher = Cipher.getInstance("AES/ECB/NoPadding");//"算法/模式/补码方式"  
		cipher.init(javax.crypto.Cipher.DECRYPT_MODE, skeySpec);
		byte[] encrypted1 = Base64.decode(sSrc);
		byte[] original = cipher.doFinal(encrypted1);
		String encoded = new String(original, "UTF-8").trim();
		return encoded;
	} catch (Exception e) {
		return "";
	}
}

base64 工具类

        <dependency>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-core</artifactId>
            <version>1.19.1</version>

另外附AES对称加解密工具类
