Question

Here are my Encryptor class methods:

    public String encrypt(String str){ 
        if(str == null || str.equals("")){
            str = "";
        }
        else{
            StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
            encryptor.setPassword(mpCryptoPassword);
            str = encryptor.encrypt(str);
        } 
    return str;
    }
    public String decrypt(String str){
        if(str == null || str.equals("")){
            str = "";
        }
        else{
            StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor();
            decryptor.setPassword(mpCryptoPassword);
            str = decryptor.decrypt(str);
        }
    return str;
    }

I am trying to encrypt as following:

String encryptedToken   = "";
//preparing token email + time
Date now            = new Date();               
String prepareToken = "email="+email+"&tokenTime="+now.getTime();

//encrypt url value
Encryptor enc       = new Encryptor();
encryptedToken      = enc.encrypt(prepareToken);

and I am decrypting like:

Encryptor enc           = new Encryptor();
String decryptedToken   = enc.decrypt(encryptedToken);

Then its throwing error:

Update
I noticed its working sometime but not working when there is + sign in the encrypted string as its getting + as space

The problem that I found is plus + sign in encrypted string. When I was decrypting it was getting + as white space from URL.

encryptedToken = encryptedToken.replaceAll(" ","+");

solve this problem
