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
Try LOAD DATA INFILE ‘file’ IGNORE INTO TABLE table CHARACTER SET UTF8 FIELDS TERMINATED BY ‘;’ OPTIONALLY ENCLOSED BY ‘”‘ LINES TERMINATED BY ‘\n’
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
You should use openssl_encrypt instead.
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.
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
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
Use encodeURIComponent() in JS and in PHP you should receive the correct values. Note: When you access $_GET, $_POST or $_REQUEST in PHP, you are retrieving values that have already been decoded. Example: In your JS: // url encode your string var string = encodeURIComponent(‘+’); // “%2B” // send it to your server window.location = … Read more
ok, i’ve found a nice alternative, which i think should work for any kind of bitmap decoding. not only that, but it also allows you to downscale using any sample size you wish, and not just the power of 2 . if you put more effort to it, you can even use fractions instead of … Read more
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.
