I have used the Apache Commons StringEscapeUtils.unescapeHtml4() for this: Unescapes a string containing entity escapes to a string containing the actual Unicode characters corresponding to the escapes. Supports HTML 4.0 entities.
Assuming the image data is already in the format you want, you don’t need ImageIO at all – you just need to write the data to the file: // Note preferred way of declaring an array variable byte[] data = Base64.decodeBase64(crntImage); try (OutputStream stream = new FileOutputStream(“c:/decode/abc.bmp”)) { stream.write(data); } (I’m assuming you’re using Java … Read more
Here I can see problems on both sides. Please keep in mind that what you get when encoding is not string, but rather an array of bytes. So in PHP you don’t need to urlencode cyphertext. base64 encoding is all you need. When you open base64_encode help you see base64_encode Encodes the given data with … Read more
There are many similar questions and useful answers in stackoverflow but I can’t find a way works both on browsers and Node.js. So I’d like to share my opinion. For html codes like < > ' and even Chinese characters. I suggest to use this function. (Inspired by some other answers) function decodeEntities(encodedString) { … Read more

You can try the following steps and code using qrtools: Create a qrcode file, if not already existing I used pyqrcode for doing this, which can be installed using pip install pyqrcode And then use the code: >>> import pyqrcode >>> qr = pyqrcode.create(“HORN O.K. PLEASE.”) >>> qr.png(“horn.png”, scale=6) Decode an existing qrcode file using … Read more
Many filetypes have a header (the first few bytes of the file) with some fixed information by which a file can be identified as a gz, png, pdf, etc. So every base64 encoded gz file would also start with a certain sequence of base64 characters, by which it can be recognized. A gzip-file always starts … Read more
There’s a much easier way to do this, using iconv – from the user notes, this seems to be what you want to do: characters transliteration // PHP.net User notes <?php $string = “ʿABBĀSĀBĀD”; echo iconv(‘UTF-8’, ‘ISO-8859-1//TRANSLIT’, $string); // output: [nothing, and you get a notice] echo iconv(‘UTF-8’, ‘ISO-8859-1//IGNORE’, $string); // output: ABBSBD echo iconv(‘UTF-8’, … Read more
The Html class is supposed to do that, however it is said that everything is not supported. It always worked for me but I never had ö so I can’t tell for this one. Try Html.fromHtml(yourStr) to get the decoded string.
Solved it using Bouncy Castle library. Here is the code: package example; import java.util.Arrays; import org.apache.commons.codec.binary.Base64; import org.bouncycastle.crypto.BufferedBlockCipher; import org.bouncycastle.crypto.CipherParameters; import org.bouncycastle.crypto.InvalidCipherTextException; import org.bouncycastle.crypto.engines.AESEngine; import org.bouncycastle.crypto.generators.OpenSSLPBEParametersGenerator; import org.bouncycastle.crypto.modes.CBCBlockCipher; import org.bouncycastle.crypto.paddings.BlockCipherPadding; import org.bouncycastle.crypto.paddings.PKCS7Padding; import org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher; public class OpenSSLAesDecrypter { private static final int AES_NIVBITS = 128; // CBC Initialization Vector (same as cipher block size) [16 … Read more
