What is your preferred method/datatype for storing passwords in a database (preferably SQL Server 2005). The way I have been doing it in several of our applications is to first use the .NET encryption libraries and then store them in the database as binary(16). Is this the preferred method or should I be using a different datatype or all...
I need to encrypt a integer, but all the crypto libraries only support strings. What is the proper method to convert a integer to a binary string in Ruby? (not '10111', I think that it's ASCII values) EDIT: I wasn't thinking about Rijndael as stream encryption. ...
I'm using application level encryption to protect sensitive data. I need to encrypt the field before I store it in the physical database and I need to decrypt it before I show it on the user interface. I'm applying the Repository pattern in the application.

I have to encrypt the output file in A application, then decrypt it in B application, but I found there are some limitations with MS encryption, if I encrypt a 1000 bytes buffer and then want to decrypt start for different position with different size in B application, the return values are error. Is there any encryption can meet my requ...
I'm developing an intranet application (C#) that uses some data (local to the web server) that we'd like to keep private. This data is encrypted (AES) using a legacy data repository. We can't totally prevent physical access to the machine. Clearly, we're never going to have perfect security here. However, we want to make it as hard as p...

Not as in "can't find the answer on stackoverflow", but as in "can't see what I'm doing wrong", big difference! Anywho, the code is attached below. What it does is fairly basic, it takes in a user created text file, and spits out one that has been encrypted. In this case, the user tells it how many junk characters to put between each ...

My company is in the process of taking over a members only website from a 3rd party. We have re-written the website and the last step is to import the existing users. We have the database with users and their passwords. We also were given the 'key' and were told that the password field is encrypted with AES encryption. I need to decr...

In order for running instances to have access to the API the credentials are sent as user data (-f) in the form of a base64 encoded shell script. For example: $ cat ec2.sh ... export AWS_ACCOUNT_NUMBER='1111-1111-1111' export AWS_ACCESS_KEY_...

What I have i...
