Why do I get incorrect values when implementing HMAC-SHA256?

阅读更多关于 Why do I get incorrect values when implementing HMAC-SHA256?

问题 I'm trying to make a function in Rust that will return a HMAC-SHA256 digest. I've been working from the description at Wikipedia and RFC 2104. I've been struggling with returning the correct HMAC. I'm using ring for the SHA256 digests but no matter what I try, I can't seem to get the right result. I suspect it might have something to do with .as_ref().to_vec() conversions. Even if that's true, I don't know how to continue from that. Not everything from RFC 2104 is implemented in the following

Xamarin PCLCrypto SHA256 give different hash

阅读更多关于 Xamarin PCLCrypto SHA256 give different hash

问题 I have a project in Xamarin Forms XAML portable. i need to get a SHA256 from a string. I use the PCLCrypto for finding my hash, because System.Security.Cryptography doesn't exist in PCL. I get a sha256 from an API to compare the values. This is the method I use to get the SHA256 hash: private string getSha256(string data) { byte[] byteData = Encoding.UTF8.GetBytes(data); var hasher = WinRTCrypto.HashAlgorithmProvider.OpenAlgorithm(HashAlgorithm.Sha256); byte[] hash = hasher.HashData(byteData)

问题 Background I have signed a file using openssl SHA256 and a private key as follows: with subprocess.Popen( # Pipe the signature to openssl to convert it from raw binary encoding to base64 encoding. # This will prevent any potential corruption due to line ending conversions, and also allows # a human to read and copy the signature (e.g. for manual verification). 'openssl dgst -sha256 -sign private.key sign_me.zip | openssl base64 > signature.sha256', stdout=subprocess.PIPE, stderr=subprocess

问题 I'm using the SJCL library to encrypt/decrypt messages. The question I have is that I don't know which is used AES or SHA256 Here is my code: var h = sjcl.codec.hex, count = 2048 ; salt = h.fromBits(sjcl.random.randomWords('10','0')); var key = h.fromBits( sjcl.misc.pbkdf2(somePassword, h.toBits(salt), count) ) ; Next I can encrypt/decrypt like var encMessage = sjcl.encrypt(key, message) ; sjcl.decrypt(key, encMessage) ; AES or SHA256 or something else ? 回答1: pbkdf2 for key generation is

How do you timestamp a sha256 certificate with a sha256 signature to secure Excel VBA Macro code in Excel 2013?

阅读更多关于 How do you timestamp a sha256 certificate with a sha256 signature to secure Excel VBA Macro code in Excel 2013?

问题 This quote was taken from an answer to another question about Excel Security settings. The answer proposed using a digital certificate to sign macros to resolve the security issue. Towards the end of the answer, it was noted that: "When you digitally sign macros, it is important to obtain a time stamp. . ." This is tricky in Office 2013, for a variety of reasons. First, there are two different ways to attach a signature to a spreadsheet. They are known as visible and invisible signatures. The

Is there a keyed SHA256 hash algorithm that is FIPS compliant for .NET?

问题 I am creating a keyed SHA256 hash using HMACSHA256 with the following code: HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(secretKey); byte[] hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(data)); string hashResult = string.Empty; for (int i = 0; i < hash.Length; i++) { hashResult += hash[i].ToString("x2"); // hex format } This is working just fine, however, it fails in a FIPS enabled environment because HMACSHA256 uses an underlying SHA256Managed implementation which is itself not
