How much of a performance hit will running everything over TLS do to my server? I would assume this is completely ignorable in this day and age? I heard once that servers today could encrypt gigabytes of data per second, is that true? And if so, is it linearly scalable so that if top speed is 10GB/second, encrypting 1GB would take 0.1 se...
Hi, Is there a way to encrypt the data file that mysql uses? I have a mysql server on an open machine, and I would like to encrypt the data file so even if someone copies the data files, they cannot read the data. Thanks ...
I have the function below ENCRYPT. Public Function Encrypt(ByVal plainText As String) As Byte() Dim key() As Byte = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24} Dim iv() As Byte = {65, 110, 68, 26, 69, 178, 200, 219} ' Declare a UTF8Encoding object so we may use the GetByte ' metho...
Hi, I have an ASP .NET 2.0 website connected to a SQL Server 2005 database. The site is pretty simple and stores information about staff, including salary. What is the best way to encrypt the salary value so no-one (including myself) can ever see what it is, except for the authorised staff using the web-app? I don't want to encrypt /...
I have an existing SQL Server 2005 database that contains data encrypted using a Symmetric key. The symmetric key is opened using a password. I am working on an upgrade to the front end applications that use this database, which include adding dozens of new tables, stored procedures, UDFs, etc. and dozens of modifications to existing ta...
I need to store encrypted data (few small strings) between application runs. I do not want the user to provide a passphrase every time (s)he launches the application. I.e. after all it goes down to storing securely the encryption key(s). I was looking into RSACryptoServiceProvider and using PersistentKeyInCsp, but I'm not sure how it wo...
I've working on a WinForms in VB.NET (3.5) application that requires the user to enter domain administrator credentials. To make things easier on the user, they should only have to enter the user name and password once, and then just rely on my app to save these credentials. I'd like to save these credentials with the other user settings...
Hello, I have a script that successfully encrypts a credit card. I need it to work as a trigger, so that any insert done to the creditcard column automatically encrypts it. Right now, my trigger works BUT the creditcard column is a varchar. When an app tries to insert, I do this: DECLARE @encryptedCreditCardNumber varbinary(max) SET @...
I'm looking for very simple encrypt and decrypt functionality for some data. It's not mission critical. I need something to keep honest people honest, but something a little stronger than ROT13 or Base64. I'd prefer something that is already included in the .Net framework 2.0 so I don't have to worry about any external dependencies. ...
I need to zip and password-protect a file. Is there a good (free) library for this? This needs to be opened by a third party, so the password protection needs to work with standard tools. ...
I'm having some trouble importing and accessing a private key with the ASPNET user. I know that when one imports a private key (.pfx file) manually, in windows, you get an option to mark the key as exportable. Now, as far as I can tell, this is needed in order to retrieve that private key later on. My problem comes in that I'm importing...
I haven't a clue about encryption at all. But I need it. How? Say you have a system of nodes communicating with each other on a network via asynchronous messages. The nodes do not maintain session information about other nodes (this is a design restriction). Say you want to make sure only your nodes can read the messages being sent. I ...
I am looking for a (preferably pure) python library to do AES 256 encryption and decryption. This library should support the CBC cipher mode and use PKCS7 padding according to the answer to an earlier question of mine. The library should at least work on Mac OS X (10.4) and Windows XP. Ideally just by dropping it into the source direct...
Hi I need to scramble the names and logins of all the users in a UAT database we have. (because of the data protection act) However, there is a catch. The testers still need to be able to login using the hashed login names so if a user login is "Jesse.J.James" then the hash should be something like Ypois.X.Qasdf i.e. approximately ...
I have this query in sql server 2000: select pwdencrypt('AAAA') which outputs an encrypted string of 'AAAA': 0x0100CF465B7B12625EF019E157120D58DD46569AC7BF4118455D12625EF019E157120D58DD46569AC7BF4118455D How can I convert (decrypt) the output from its origin (which is 'AAAA')? ...
I would like to save data in cookies (user name, email address, etc...) but I don't the user to easily read it or modify it. I need to be able able to read the data back. How can I do that with php 5.2+? It would be used for "welcome back bob" kind of feature. It is not a replacement for persistence or session storage. ...
Are JKS (Java Key Store) files encrypted? Do they provide full protection for encryption keys, or do I need to rely solely on access control? Is there a way to ensure that the keys are protected? I'm interested in the gritty details, including algorithm, key management, etc. Is any of this configurable? ...
I recently encountered an odd problem with RSACryptoServiceProvider.VerifyHash. I have a web application using it for decryption. When users running the web service were doing so over our VPN it became very very slow. When they had no connection or a internet connection they were fine. After much digging I found that every time RSACry...
