encryption

问题 I have an array of JSON arrays whose values I am trying to encrypt with CryptoJS and then print for use in another file, where these values should be decrypted using a user-given passphrase. But I am doing something wrong and I am getting "Uncaught Error: Malformed UTF-8 data" when decrypting the URL's. encrypt.js: var encrypted = CryptoJS.AES.encrypt(item[key], pass); json[j] += encrypted.ciphertext.toString(CryptoJS.enc.Base64); decrypt.js: var decrypted = CryptoJS.AES.decrypt(item[key],

问题 I writing a C# sniffer to decrypt a TLS packet which I already have the private key for. Here is a screenshot of the TLS packet. I have tried decrypting the bytes in "Encrypted Application Data", but I am getting the error, "The parameter is incorrect" which usually means the data isn't correct for the provided key, so the question is, am I decrypting the wrong bytes? The private key I have is from a .pem file in the section -----BEGIN PRIVATE KEY-----. I think this .pem file is generated

问题 I am attempting to write the decryption function for an RSA encryption system, everything seemed to be working fine for very small numbers, however sometimes the output just isn't correct (I think that the cause may be a floating point error or some kind of stack overflow). The process which is causing me problems can be simplified to (11^23) mod 187 but I will include the full code in case anybody wants to see it. I know that the answer should be 88 as it is the example used in Appendix J of

问题 Trying to use the javax.crypto library to encrypt a string and store it in the database (Oracle). I will need to decrypt this string later, so I need a two-way algorithm. The problem is the database doesn't seem to accept some of the encrypted characters the method creates. We are in between migrating our databases to a new server. The old databases use US7ASCII charset while the new databases use AL32UTF8. When I go to put the encrypted string in the database, the database just converts them

问题 I am trying to generate the same list of random sequences using the function "genKeys". Using the same seed, I will get the same list, but only on my Laptop. Running this code on my Raspberry Pi, I get a completely different list. I guess the RNG is different. Is there a way to "unify" the way numbers being generated or to implement an algorithm that will generate the same numbers? def genKeys(number, seed, length): rng = random.Random(seed) seq =

问题 hi I am using a Kingston DT4000 G2 USB drive with password protected. I could track disk plug in & out event under windows by calling RegisterDeviceNotification(), and receive notification by WM_DEVICECHANGE; While the problem is the media is not available till I input password. Before decryption I could see the device and system will show "Please insert a disk into USB drive (E:)". But I can't capture the event when data is decrypted and media is really available to me. Is there a such event
