aes

Ref: Android encryption/decryption issue (AES) I am building an android app which requires aes decryption of a really large package (~50Mb) and it is really slow when implemented in android's inbuilt aes decryption mechanism (around 5 minutes). Based on the above posts in SO, I attempted to use ndk and tried to download native libraries (openssl) to use for this app. However, openssl for android has a really large number of files and I do not know which ones to use to create the .so file. I am quite inexperienced with the use of ndk and native code in android apps and would find any

I'm currently working on an key-handling class in Java, specifically using a KeyStore. I'm trying to generate a SecretKey with an AES instance, then place it inside of the KeyStore using the setEntry() method. I've included the relevant sections of my code: // The KS Object private KeyStore keyStore; private KeyStore.SecretKeyEntry secretKeyEntry; private KeyStore.ProtectionParameter protectionParameter; private KeyGenerator keyGenerator; private SecretKey secretKey, newSecretKey; keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); keyGenerator = KeyGenerator.getInstance("AES");

I always get the same error 3045: The Currency field is missing, when posting this form: <form name="frmPay" action="https://test.sagepay.com/gateway/service/vspform-register.vsp" method="POST"> <input type="text" name="VPSProtocol" value="3.00" /> <input type="text" name="TxType" value="PAYMENT" /> <input type="text" name="Vendor" value="myvendor" /> Crypt:<textarea rows="10" cols="200" name="Crypt"><%=Crypt%></textarea> <input type="submit" value="Send" /> </form> I think the error is in the encryption Could someone send encryption routine for classic ASP?

So my question for you stackoverflow geniuses is: if there a way (native, library, framework, whatever..) to encrypt data with AES (preferably 128 but could be 256 too) using a strong Authenticated encryption algorithm , let's say GCM mode ? Question is short, I have done some research and I only found one library that seems to support it ( RNCryptor ) but it also seems to use password to crypt instead of keys (like you provide a password and the library made the key) and I don't like that a lot, I prefer to manage my keys myself . I also look at CommonCryptor.h and I found that line, which

I tried to implement a "very" simple encryption/decryption example. I need it for a project where I would like to encrypt some user information. I can't encrypt the whole database but only some fields in a table. The database and most of the rest of the project works, except the encryption: Here is a simplified version of it: #include <openssl/aes.h> #include <openssl/evp.h> #include <iostream> #include <string.h> using namespace std; int main() { /* ckey and ivec are the two 128-bits keys necessary to en- and recrypt your data. Note that ckey can be 192 or 256 bits as well */ unsigned char
