I tested the encryption/decryption programs which work OK together. However if I encrypt anything with the mentioned code and then try to decrypt it by openssl tool built-in in linux, I just can't get decrypt it, it even logs me the bad magic number error. Same, if I encrypt anything with openssl and try to decrypt with the code won't work. I tried with both cbc ecb. If they're both implementing AES, shouldn't it work same way? 回答1

I'm successfully decrypting the value if i use AES-128-CBC using this code on the android device, but failing the AES-256-CBC cypher and i don't understand where the problem is ! The code : public static String decrypt(byte[] keyValue, String ivValue, String

Looking at the class code and javadoc reference , the AESEngine is a 128bit instead of a 256 bit block cipher Searching trough the code and docs i could not find the 192 or 256 bits implementations. Where are them? For completeness, this is the core of my actual ciphering class: private void init(String passphrase) { try

All these functions are soft-deprecated. Please use tidy evaluation idioms instead (see the quasiquotation section in aes() documentation). But the aes() examples use NSE ( ie , g1(mpg) instead of g1("mpg") ). Likewise, these SO solutions

I am trying to open a file with undetermined length, encrypt it and write another file with the ciphertext generated, then open the ciphered file and recover the plaintext. I need to use a file of a

Sample data: set.seed(100) df <- data.frame(ab.class = c(rep("A", 200), rep("B", 200)), val = c(rnorm(200, 0, 1), rnorm(200, 1, 1))) The unlabelled density plot is generated and looks as follows: ggplot(df, aes(x = val, group = ab.class)) + geom_density(aes(fill = ab.class), alpha = 0.4) What I want to do is add text labels somewhere near the peak of each density, showing the number of samples in each group. However, I cannot find the right combination of options to

The problem that i am facing is that the signatures of the Encrypt and Decrypt methods in asp vs C# are different. here is my asp code for decrypting, which wraps the decrypt code.
