Raw RSA Encryption With VB

Nov 15, 2011

I am attempting to create a program that can do raw RSA encryption (performing the encryption without using 'Encrypt' and 'Decrypt') of a user's message that can contain a-z, A-Z, 0-9, and [,.;:'"()]. I've attached a screen shot of the application form.

Basically, the user will pick from a list of prime numbers from the first box and input them into p and q. They will type their message in the designated textbox and then hit <encrypt> which will encrypt using p and q and then show the encrypted message below. I'll leave out the Key box since that deals with the math behind the encryption.

The part I am stuck on right now is assigning a number to each one of the characters so that it can be encrypted. These numbers need to remain the same so that the message can be decrypted as well.

.net Encryption Result Does Not Match The Xcode Encryption Result Given The Same Input Parameters?

Jun 21, 2011

I have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.

this is the vb.net code:

Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

Encryption App Using Xor .net?

Jan 28, 2011

I have been trying to create an app that will do xor encryption. I have tried a few different functions but none of them seem to give me what I want. I need it to put the coded text into a 7 bit ascii string. For example if the key was a - 1100001 and the text to be encrypted was s - 1110011 then it would return 0010010 as the encryption. One of the pieces of code I tried to use

Public Function XOREncryption(ByVal CodeKey As String, ByVal DataIn As String) As String
Dim lonDataPtr As Long
Dim strDataOut As String
Dim temp As Integer

[code]....

This returns a hex digit though which will not work for what I want.

Getting AES-Encryption Work In .NET?

I have a problem with an encryption made in AdobeFlex and which I need to translate to VB.NET.The core is a AES Encryption, but I tried several ways and code and the encrypted strings weren't the same The original Flex Sourcecode is:

VB
private function encryptAES(arg1:String, arg2:String, arg3:String="aes128-cfb8", arg4:String="None"):String
{
var loc1:*=com.hurlant.util.Hex.toArray(com.hurlant.util.Hex.fromString(arg2));

RSA Private Key Encryption?

Aug 10, 2009

I'm looking to use RSA Asymmetric encryption to encrypt some data. I've read this article on the forums with a similar title, but it did not answer my question. What I would like to do is use the private key of an RSA key combination to encrypt (sign?) the data and use the public key to decrypt (verify?), as per this wikipedia article . I would like to use this method because I want people to be able to read the data, but not create it themselves. I've copied the code from Peter Bromberg's article RSA Encryption in .NET Demystified , but always get an exception with the "Bad Key" message. If I use the public key for decryption, it works fine (the opposite of what I want). use the public key for encryption.

VS 2010 Getting The AES-256-CBC Encryption?

Apr 19, 2012

i have in php two functions, one to encrypt and one to decrypt.

PHP
function Encrypt($message) {$Method = "AES-256-CBC";$passPhrase = "key";$iVector = 1234567890123456;$encryptedMessage = openssl_encrypt($message, $Method, $passPhrase, $iVector);return $encryptedMessage;}function Decrypt($message) {$Method = "AES-256-CBC";$passPhrase = "key";$iVector = 1234567890123456;$decryptedMessage = openssl_decrypt($message, $Method, $passPhrase, $iVector);return $decryptedMessage;}

what i want to do, is encrypt a message, using the same method in vb.net as i do in php, how would i go about doing this?

Which Encryption Method Is Better?

Aug 9, 2009

I've seen a lot of threads on the web discussing about which encryption algorithm is better.According to what I've read, AES encryption algorithm is based on Rijndael's algorithm, and the first is the one being implemented by the US's government to secure TOP SECRET files.From what I've tried RijndaelManaged only supports 128bit long keys (that would be a byte array with 16 byte values, right?) and not 256 as I had first thought; however, AES seems to support 256bit keys (or is it all the way around?), I haven't personally tried DES nor TripleDES.

So, which one is better or more secure? And what's up with asymmetrical encryption? What's the difference? Can both symmetrical and asymmetrical encryption be used for the same thing?

Compressible Encryption In PST File?

I would like to read the contents of an existing Outlook 2007 PST file by VB.Net. I find already the file and record structure, this is not a problem. But I have a problem with the compressible encryption how is used. Now I have read that this encryption is based on a simple byte-substitution cipher with a fixed substitution table. But unfortunately I can't find this table. Maybe someone can help me where to find this table or where I to find all the necessary information about compressible encryption.

Encryption - Encrypt In .NET With AES-256 And Decrypt In Air?

Jul 28, 2011

I am trying to encrypt a zip in VB.NET to send to an android device using Air. Then once its on the device, decrypt it using the key and IV.

Here is part of my VB.NET Code:

Private Sub EncryptBytes(ByVal fileIn As String, ByVal fileOut As String, ByVal pass As String, ByVal ivString As String)
Dim crypt As New RijndaelManaged
crypt.KeySize = 256

[Code]...

This is not working ... Note that I tried to write a PKCS7 class based on a Java class I found. The hurlant package I downloaded only had PKCS5. VB.NET did not provide any of the same padding classes as hurlant comes with. I wish I could using "None" but I couldn't get passed the error in VB.I think there may also be an issue with the way I am converting a string into a byte array in VB vs Air.
