I need to protect my program from disassembly. The first attempt would be by encrypting the program and decrypting its parts when needed. Perhaps encrypting again when decrypted code is executed. Please give me a clue, how create this type of defense. Obviously without assambler this task is difficult, but I haven't found many resource...

The HSM has been working 24x7 for 7 days continuous...
I wonder which class is the class that I use to encrypt data (first time string data) and the best method of encryption (among those supported by caché). Must generate a strong encryption for data in my project. Any help is welcome. If someone can show me some example, I'll be even more grateful. ...
A web application contains sensitive data of the users. Neither the operator of the web application nor the hosting provider should be able to see this data. Therefore I wanted to store these data in the DB encrypted with the entrance password of the users. dataInDB = encrypt (rawData, user password) With this strategy it is however...

When the user clicks that link, I first decrypt the string and t...

I'm trying to share authentication between an ASP.NET app and another UNIX-based app, where the hashed password is stored in the database. I need to ensure the hashing algorithms on both platforms match. This is how I'm hashing in C#: var sha1 = new SHA1CryptoServiceProvider(); var passwordBytes = Encoding.UTF8.GetBytes(password); var...
I'm trying to use an AES 256 encrypted password instead of a plain text password. I'm not sure how to configure the server to use an AES encrypted password.

We have a web app, which is written in Java, and storing data into a PostgreSQL database. We'd like to encrypt a few fields in our database, as well as some uploaded documents. However, these all need to be 2-way encryption (ie, we need to be able to decrypt them), and decryption needs to be fairly fast. However, we cannot come up wit...
Hi, I am wondering if it is possible to generate a "key" that is valid for a period of (approximately) three months? For example, let's say (hypothetically) that I generate a key like this (pseudocode): Key = HASH ( MachineID, Salt ); And the way I verify a key is valid is to check like this: isValid(Key) { return Key == HASH ( ...
I am looking to generate passwords using strings typed by the user, the book I am reading recommends using sha over md5 because it is considered stronger. sha however has been deprecated and I am now using the hashlib module to encrypt me strings in a similar way to that shown here: http://docs.python.org/py3k/library/hashlib.html#modul...
I have an ASP.NET 1.1 form gathering data on a public-facing site, within a DMZ. The data is represented by a serializable class. My problem is that I need to serialize, encrypt and transmit the data to a Web Service running on an internal server - the service logic should then decrypt and deserialize the data before writing the XML to a...
This will be a bit difficult to explain but I will try my best. There is a website that has the login form on every page with username/password fields. These pages are not using SSL. After the user fills in the username/password and submits the form, the form is sent to an authentication page which is https. I have a few questions about...
