"Java" (1) BASE64 encryption technology

1. JDK

/** * Use JDK to implement Base64 encryption */public static void JdkBase64 () {try {Base64encoder encoder = new Base64encoder (); String encode = Encoder.encode (Src.getbytes ()); System.out.println ("Encode:" + encode); Base64decoder decoder = new Base64decoder (); System.out.println ("Decode:" + New String (Decoder.decodebuffer (encode));} catch (IOException e) {e.printstacktrace ();}}

In the case of using this method, there may be a situation where base64encoder cannot be found, which resolves:

2. Commons Codec

/** * Use Commonscodes to implement Base64 encryption */public static void CommonsCodesBase64 () {byte[] encodebytes = base64.encodebase64 ( Src.getbytes ()); System.out.println ("Encode:" + new String (encodebytes)); byte[] decodebytes = base64.decodebase64 (encodebytes); System.out.println ("Decode:" + new String (decodebytes));}

3. Bouncy Castle

/** * Use Bouncycastle to implement Base64 encryption */public static void BouncyCastleBase64 () {byte[] encodebytes = Org.bouncycastle.util.encoders.Base64.encode (Src.getbytes ()); System.out.println ("Encode:" + new String (encodebytes)); byte[] Decodebytes = Org.bouncycastle.util.encoders.Base64.decode (encodebytes); System.out.println ("Decode:" + new String (decodebytes));}
