Simple encryption of an email address that will be in my querystring

The goal of this is not for security, but for obscurity so the casual user will not be able to determine what the email address is.

I don't want to display an email address in the URL like:

www.example.com/[email protected]

I would like to encrypt the email address, with the goal of:

  1. the encrypted text should be encodable to be in a querystring
  2. the length should be as short as possible
  3. should not be easily decryptable e.g. using md5
  4. I can decrypt the value back

Can someone suggest an ecryption algorith that would meet the above criteria?

When you talk about encryption you would have bytes, and not characters. Bu you can encode those bytes as characters using Base64. For example:

import javax.xml.bind.DatatypeConverter;

// Encrypt if you really need to encrypt it
// I am assuming you have a method that receive a String, encrypt it and return the byte[] encrypted.
// If you don't know how to encrypt, just ask a new question about how to do it in Java.
byte[] b = encrypt( "[email protected]" );
String encoded = DatatypeConverter.printBase64Binary( b );

// Otherwise, just encode it
b = "email.example.com".getBytes(java.nio.charset.StandardCharsets.UTF_8);
encoded = DatatypeConverter.printBase64Binary( b );

If your aim is not to deal with Security aspect of it then you can achieve it through Base64 encoding and decoding of String

 final String encodedValue =  new BASE64Encoder().encode("[email protected]".getBytes());
System.out.println("encodedValue = "+encodedValue );
final String decodedValue =  new String(new BASE64Decoder().decodeBuffer(encodedValue));
System.out.println("decodedValue = "+decodedValue);
