I am trying to convert base64 String to byte array but it is throwing following error
java.lang.IllegalArgumentException: Illegal base64 character 3a
I have tried following options userimage is base64 string
byte[] img1 = org.apache.commons.codec.binary.Base64.decodeBase64(userimage);`
/* byte[] decodedString = Base64.getDecoder().decode(encodedString.getBytes(UTF_8));*/
/* byte[] byteimage =Base64.getDecoder().decode( userimage );*/
/* byte[] byteimage = Base64.getMimeDecoder().decode(userimage);*/`
You can use java.util.Base64
package to decode the String to byte[]
.
Below code which I have used for encode and decode.
For Java 8 :
import java.io.UnsupportedEncodingException;
import java.util.Base64;
public class Example {
public static void main(String[] args) {
try {
byte[] name = Base64.getEncoder().encode("hello World".getBytes());
byte[] decodedString = Base64.getDecoder().decode(new String(name).getBytes("UTF-8"));
System.out.println(new String(decodedString));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
For Java 6 :
import java.io.UnsupportedEncodingException;
import org.apache.commons.codec.binary.Base64;
public class Main {
public static void main(String[] args) {
try {
byte[] name = Base64.encodeBase64("hello World".getBytes());
byte[] decodedString = Base64.decodeBase64(new String(name).getBytes("UTF-8"));
System.out.println(new String(decodedString));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
