This works fine when using aes , but doesn't work like expected when using aes_string . Is there a workaround to make it work with aes_string ? require(ggplot2) # Define the format function dot <- function(x, ...) { format(x, ..., big.mark = ".", scientific = FALSE, trim = TRUE) } # Create dummy data df <- data.frame(cbind(levels(iris$Species),c(10000000000,200000,30000))) df$X2 <- as.numeric(as.character(df$X2)) # Works with aes ggplot(iris) + geom_bar(aes

I have almost no idea about encryption, could not figure out where to fix. I would really apreciate your feedback.

What possible ciphers can I specify to stream context in the PHP NUSOAP SoapClient creation? <?php $objSoapClient = new SoapClient( "https://example.com/?wsdl", array( "encoding"=>"ISO-8859-1", "stream_context"=>stream_context_create( array( "ssl"=>array("ciphers"=>"<????>") ) ) ) ); ?> 回答1: TLS v1.2 is described in RFC5246 , you can read it here . List of ciphers you can find in openssl wiki , use the second line without trailing 256 . You can manually get a list of ciphers used by

I am trying to decrypt a string in android.

I have a problem with my code, when I encrypt data, for example, in this case, the simmetric key I encrypted with the receiver's public key, then saved to a text file, when I read that text file and try to decrypt it, using the receiver's private key, I get a different key, therefore I cannot use it to decrypt the encrypted message. Sender's code: import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.security.KeyStore; import java.security.MessageDigest; import java.security.PrivateKey; import java.security.PublicKey;

AES key may be generate by this code KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(128); but If I have a "very reliable" method of generating random numbers can I use it in such a way SecureRandom rnd = new SecureRandom(); byte[] key = new byte[16]; rnd.nextBytes(key); is key obtained by this method reliable ? or it ONLY must generated by some SPECIAL algorithm The AES key can be any 128 bits. It should be be practically unguessable, whatever the method of creating it. For Example: SecureRandom sr = new SecureRandom() key = new byte[16]; iv = new byte[16]; sr.nextBytes(key);

I need a little help here.So basically I have to make a test of AES encryption/decryption of an image in Android.I'm new in android programming and that's why a friend of mine give me an example of how to do it, but the problem is that when I run the sample it crashes after like 20-30 seconds and I'm not really sure what's happening.So can anyone please look at the code and tell me where is the problem.The sample code needs to do this : Encrypt and Decrypt the same image and show me a log with info, how long it takes to encrypt and decrypt the image.Thanks anyway!
