encryption

问题 I have a file which has been encrypted by des.exe. A file can be encrypted and decrypted using the following commands: des -E -k "foo" sample.txt sample.txt.enc des -D -k "foo" sample.txt.enc sample.txt.dec I have attempted to decrypt using the following: public byte[] Decrypt(FileInfo file, string key) { byte[] keyAsBytes = LibDesPasswordConvertor.PasswordToKey(key); byte[] initializationVector = keyAsBytes; var cryptoProvider = new DESCryptoServiceProvider(); cryptoProvider.Mode =

问题 If we look at the Jenkins job logs, we can see that the text contained there, is exactly the same as what is displayed in the browser when you look into the Console Output EXCEPT for the URL that in the log files is encoded with something with the tag [8mha: Does anyone know how can we "decrypt" it? Already tried a simple base64 but it doesn't work. This is one of those strings [8mha:AAAAqR+LCAAAAAAAAP9b85aBtbiIQSajNKU4P08vOT+vOD8nVc

问题 I have an issue with the decryption in the following code. I have a encrypted string being sent to setData(). I am trying to decrypt the encrypted string(data). The error I keep getting is javax.crypto.IllegalBlockSizeException: last block incomplete in decryption byte[] data; String key = "tkg96827pco74510"; byte[] encryptedOut; String decryptedOut; Key aesKey; Cipher cipher; public void setData(String dataIn){ this.data = dataIn.getBytes(); try { aesKey = new SecretKeySpec(key.getBytes(),

问题 I have a problem when I encode/decode Base64 between Java and Android. Here is my case: I write code to encrypt/decrypt using ECC on Java, my code work very well. Then I try to encrypt string on Java and decrypt this encrypted string on Android, it fail. I think the problem maybe encode/decode Base64. Here is my code: Encrypt/decrypt on Java only: //ENCRYPT try { Cipher c = Cipher.getInstance("ECIES",BouncyCastleProvider.PROVIDER_NAME); c.init(Cipher.ENCRYPT_MODE,publicKey); encodeBytes = c

问题 I have an interesting encryption problem at hand. I do not know if it can be solved but here goes: A database is to contain sensitive user information. As such, the user information must be encrypted (two way encryption). The user has a login / password and these may be used in the two way encryption. Now, the encryption is to be designed in such a way that even the administrator viewing the database tables should not be able to make sense of the user information. However, the design has to

问题 I want to encrypt rest api path parameter in apache camel(springboot) spring dsl . I have tried different methods using crypto dataformat on camel but it was not working. I have added camel crypto 2.14.0 I am new in this technology.i know the below code is wrong. I tried Below code <route streamCache="true" trace="true" errorHandlerRef="globalErrorHandler"> <from uri="direct:getCustomerPortfolio" /> <to uri="direct-vm:routeProcessor" /> <setHeader headerName="CamelHttpMethod"><constant><
