Encrypt AES with C# to match Java encryption

由 时光怂恿深爱的人放手 提交于 2019-11-27 12:34:00
问题 I have been given a Java implementation for encryption but unfortunately we are a .net shop and I have no way of incorporating the Java into our solution. Sadly, I'm also not a Java guy so I've been fighting with this for a few days and thought I'd finally turn here for help. I've searched high and low for a way to match the way the Java encryption is working and I've come to the resolution that I need to use RijndaelManaged in c#. I'm actually really close. The strings that I'm returning in

Getting SlowAES and RijndaelManaged class in .NET to play together

由 核能气质少年 提交于 2019-11-27 12:28:58
I'm trying to setup AES encryption / decryption using the javascript library SlowAES and the RijndaelManaged class in .NET. I chose this method after reading this post , where Cheeso has managed to get these two encryption methods to play together "In my tests of the COM-wrapped-SlowAEs, I used CBC mode, and the encryption was completely compatible with the RijndaelManaged class in .NET" - Cheeso I've taken the javascript code from Cheeso's Windows Scripting Component, the latest slowaes libraries, and using the following javascript script to test: var key = "12345678901234567890123456789012";

Why are RijndaelManaged and AesCryptoServiceProvider returning different results?

Here is the example that I have run. It has the same Mode, Padding, BlockSize, KeySize. I am using the same init vector, key and data. Using the RijndaelManaged produces an encrypted value of: 0x8d,0x81,0x27,0xc6,0x3c,0xe2,0x53,0x2f,0x35,0x78,0x90,0xc2,0x2e,0x3b,0x8a,0x61, 0x41,0x47,0xd6,0xd0,0xff,0x92,0x72,0x3d,0xc6,0x16,0x2b,0xd8,0xb5,0xd9,0x12,0x85 Using the AesCryptoServiceProvider produces an encrypted value of: 0x8d,0x9f,0x6e,0x99,0xe9,0x54,0x8b,0x12,0xa9,0x88,0x1a,0x3d,0x65,0x23,0x9c,0x4e, 0x18,0x5a,0x89,0x31,0xf5,0x75,0xc5,0x9e,0x0d,0x43,0xe9,0x86,0xd4,0xf3,0x64,0x3a Here is the code I

How to decode Rijndael in ruby (encoded in VB.net)

问题 I am using Rinjael to encode in VB.NET and need to decode in Ruby. My VB.NET encryption class looks like this: Private Class Encryptor Private symmetricKey As System.Security.Cryptography.RijndaelManaged Private iVector As Byte() Private Key As Byte() Public Function encrypt(ByVal data As String) As String Try Dim plainTextBytes As Byte() = System.Text.Encoding.ASCII.GetBytes(data) Dim encryptor As System.Security.Cryptography.ICryptoTransform = symmetricKey.CreateEncryptor(Key, iVector) Dim

Passphrase, Salt and IV, do I need all of these?

问题 If I am using Rijndael CBC mode, I have no idea why we would need salt. My understanding is even if people know the password, but he cannot get the data without IV. So from my perspective, password + IV seem to be sufficent secure. Do I get anything wrong? 回答1: Yes, you need all of these things. Salt (and an "iteration count") is used to derive a key from the password. Refer to PKCS #5 for more information. The salt and iteration count used for key derivation do not have to be secret. The

问题 Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. I can\'t seem to find a nice clean example of using AES 128 bit encryption. Does anyone have some sample code? 回答1: If you just want to use the built-in crypto provider RijndaelManaged, check out the following help article (it also has a simple code sample): http://msdn.microsoft.com/en-us/library/system.security
