Base64 Java encode and decode a string [duplicate]
You can use following approach: import org.apache.commons.codec.binary.Base64; // Encode data on your side using BASE64 byte[] bytesEncoded = Base64.encodeBase64(str.getBytes()); System.out.println(“encoded value is ” + new String(bytesEncoded)); // Decode data on other side, by processing encoded data byte[] valueDecoded = Base64.decodeBase64(bytesEncoded); System.out.println(“Decoded value is ” + new String(valueDecoded)); Hope this answers your doubt.
