I'm decoding some previously-encoded data with the following: SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.DECRYPT_MODE, skeySpec); byte[] decrypted = cipher.doFinal(encrypted); When using BC 1.45 I get this exception: javax.crypto.BadPaddingException: pad block corrupted at org.bouncycastle.jce.provider.JCEBlockCipher.engineDoFinal(JCEBlockCipher.java:715) at javax.crypto.Cipher.doFinal(Cipher.java:1090) EDIT: More about this

Once The contents are read it will encrypt them in AES 256 CBC and save the ciphertext to a file called ciphertext. Once this is saved it will close both files. Then will open the cipher text from the file that was just saved and decrypt the cipher text and save it to a file called decrypted. My Problem: It seems to never decrypt my cipher text. I get garbage, I have no idea what I am doing wrong. Please help. #include #include #include

I'm looking for a way to get ggplot to display the percentage of values in that category. Of course, it is possible to create another variable with the calculated percentage and plot that one, but I have to do it several dozens of times and I hope to achieve that in one command. I was experimenting with something like qplot(mydataf) + stat_bin(aes(n = nrow(mydataf), y = ..count../n)) + scale_y_continuous(formatter = "percent") but I must be using

I have a good knowledge of PHP but little knowledge about cryptography. I know the key and the iv of the crypted file. The file is decrypting fine as whole but the real issue arises when I try to decrypt the partial file from the middle. It decrypts fine when I try to decrypt the first 128kb of the file or 256kb or any length from the beginning of the file. but when I start from the middle, it does not

It is a government computer, so I'm not sure how that will fly. I've seen posts on the msdn blog sites that say they are working on an AES FIPS compliant version, but I cant seem to find out anything more. Does anyone know when this might happen? 回答1: I never realized this before this question, but you're right. The constructor has this: public RijndaelManaged() { if (Utils

I have read all the posts out there about this padding issue - which can often be caused by an incorrect key (possibly the case here - but I'm not seeing it.
