编码
public String decrypt(String CipherText) {
try {
byte[] raw = decoder.decodeBuffer(CipherText);
byte[] stringBytes = decrypt_cipher.doFinal(raw);
String PlainText = new String(stringBytes, "UTF8");
return PlainText;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
public String encrypt(String PlainText) {
try {

在server端是这样的，每个thread有一个单独的加密的Crypto class,不过变量都是独
立的，这样也会出问题吗？那应该怎么解决呢？整个类的代码如下
public class Crypto{
private SecretKeySpec skey;
private Cipher encrypt_cipher;
private Cipher decrypt_cipher;
private BASE64Decoder decoder;
private BASE64Encoder encoder;
public Crypto(String str_key) {
try {
BASE64Decoder b64decoder = new BASE64Decoder();
this.skey=new SecretKeySpec(b64decoder.decodeBuffer(str_skey),"
AES");
this.encrypt_cipher = C

Are all these variables assigned on a per-thread basis?
