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

由 邮差的信 提交于 2019-12-24 02:45:26
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

问题 I've been trying to perform a straight forward SHA256 HMAC using wincrypt/cryptoapi/Cryptography API: Next Generation (CNG) and i'm really struggling. My target is Windows 8. I can not find the correct methods or find any examples anywhere. I am looking to do the following in C/C++, that is demonstrated in C# below HMAC hashMaker = new HMACSHA256(Encoding.ASCII.GetBytes("SecretKey")); byte[] hash = hashMaker.ComputeHash(Encoding.ASCII.GetBytes("<SomeXmlData />")); string hashStr =

问题 I have a string and a key, which i want to generate an HMAC SHA256 from it. Although i'm using 2 libs IDZSwiftCommonCrypto and CryptoSwift and this answer Nothing really worked for me. My source of truth are those 2 websites https://myeasywww.appspot.com/utility/free/online/Crypt_Decrypt-MD5-AES-HMAC-SHA-DES-RABBIT/en?command=UTILITY&ID=2 and https://www.freeformatter.com/hmac-generator.html#ad-output Which they always generate the correct hash key for my case. Any idea in what can work here?

问题 I'm trying to hash an API secret using hmac. But I can't get it to work using Python 3.5. Here's the problem code: sign = hmac.new(self.Secret, post_data, hashlib.sha512).hexdigest() Here's the error: TypeError: key: expected bytes or bytearray, but got 'str' I've tried encoding first like so... secret = b'api_secret_here' Also tried... sign = hmac.new(self.Secret.encode('utf-8'), post_data, hashlib.sha512).hexdigest() and... sign = hmac.new(self.Secret.encode(), post_data, hashlib.sha512)

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> SSL：（Secure Socket Layer，安全套接字层），位于可靠的面向连接的网络层协议和应用层协议之间的一种协议层。SSL通过互相认证、使用数字签名确保完整性、使用加密确保私密性，以实现客户端和服务器之间的安全通讯。该协议由两层组成：SSL记录协议和SSL握手协议。 　　TLS：(Transport Layer Security，传输层安全协议)，用于两个应用程序之间提供保密性和数据完整性。该协议由两层组成：TLS记录协议和TLS握手协议。 　　SSL是Netscape开发的专门用户保护Web通讯的，目前版本为3.0。最新版本的TLS 1.0是IETF(工程任务组)制定的一种新的协议，它建立在SSL 3.0协议规范之上，是SSL 3.0的后续版本。两者差别极小，可以理解为SSL 3.1，它是写入了RFC的。 　　SSL (Secure Socket Layer) 　　为Netscape所研发，用以保障在Internet上数据传输之安全，利用数据加密(Encryption)技术，可确保数据在网络上之传输过程中不会被截取。目前一般通用之规格为40 bit之安全标准，美国则已推出128 bit之更高安全标准，但限制出境。只要3.0版本以上之I.E.或Netscape浏览器即可支持SSL。 　　当前版本为3

Passing hashed data as key to hash again returns incorrect results

问题 I'm creating a script that will access AWS services using GAS. I'm using the hashing functions in the Utilities library for all the hashing that is required to create a v4 signature. These functions appear to be able to successfully hash data once, but trying to pass in hashed data into an argument yields incorrect results. Anyone else run into this issue and figure it out? I know there is something weird going on with Utilities.computeHmacSha256Signature( input, key ) , because the arguments

crypto createHMAC output differs according to nodejs version

由 自作多情 提交于 2019-12-21 19:58:25
问题 I have issues with crypto module while upgrading my node version. The created HMAC depends on the version of node. You'll find below the piece of code that reproduces the problem. If I encode my key as BASE64 (or any) the HMAC does not depends on node.js version. If I encode it as binary, the HMAC is different if I change my node.js version. [EDIT] according to Why crypto.createHash returns different output in new version? I have added the encoding when calling the update function code
