使用阿里大于API发送短信，但阿里没有提供NetCore 的API,自己看了下源码重写了发短信这个部分 public class MessageSender { private readonly string _appKey; private readonly string _appSecret; private readonly string _serverUrl; public MessageSender(string url, string appKey, string appSecret) { _serverUrl = url; _appKey = appKey; _appSecret = appSecret; } public string SmsType { get; set; } = "normal"; public string SmsFreeSignName { get; set; } = "生日提醒"; public string SmsParam { get; set; } public string RecNum { get; set; } public string SmsTemplateCode { get; set; } = "SMS_24695114"; public string GetApiName() { return "alibaba

jsSHA, CryptoJS and OpenSSL libraries giving different results

由 淺唱寂寞╮ 提交于 2019-12-30 05:05:50
问题 New to JS, I'm also learning to use crypto libraries. I don't understand why signing/encoding the same message with the same secret yields differing results. I'm using jsSHA 1.3.1 found here, and CryptoJS 3.0.2 described here trying to create a base64 sha-1 encoded hmac signature. Here's the code: In html... <script src="lib/jsSHA/src/sha1.js"></script> <script src="http://crypto-js.googlecode.com/svn/tags/3.0.2/build/rollups/hmac-sha1.js"></script> And in js... var message = "shah me"; var

HMAC security - Is the security of the HMAC based on SHA-1 affected by the collisions attacks on SHA-1?

问题 Is the security of the HMAC based on SHA-1 affected by the collisions attacks on SHA-1? 回答1: The security implications of HMAC are described in detail in the security section of the RFC. In a nutshell, a very strong attack indeed is required before the security of the HMAC is threatened; the existing collision attacks on SHA-1 certainly don't constitute such. HMAC is specifically designed to make attacks difficult, and ordinary collision attacks won't generally suffice: The security of the

HMAC-SHA256 in Delphi

由 我们两清 提交于 2019-12-29 06:54:13
问题 I need to generate HMAC-SHA256 signatures for the Amazon web services API. The old DCPcrypt library has sha256 routines but does not do HMAC signing. Anyone know of a free hashing library I could use? 回答1: After a little more searching I found OpenStreamSec - which looks like it was abandoned a few years ago but still compiles in D2007. http://sourceforge.net/projects/openstrsecii/ Generating a HMAC-256 for Amazon is really simple: StrToMime64(HMACString(haSHA256, SecretKey, 32, DataToHash));

Using HMAC-SHA1 for API authentication - how to store the client password securely?

由 我怕爱的太早我们不能终老 提交于 2019-12-29 02:52:26
问题 In a RESTful API that uses S3-style authentication, the API client signs the request with his secret key using HMAC-SHA1, so the secret key is never transmitted over the wire. The server then authenticates the client by using that client's secret key to repeat the signature process itself and compare the result to the signature transmitted by the client. This is all nice and good but it means the the server requires access to the plaintext of the client's shared secret. That flies in the face

hashlib模块

由 大兔子大兔子 提交于 2019-12-27 16:02:04
hashlib模块: 1.>什么叫hash:hash是一种算法（3.x里代替了md5模块和sha模块，主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ，MD5 算法）， 该算法接受传入的内容，经过运算得到一串hash值. 2.>hash值的特点是： 只要传入的内容一样，得到的hash值必然一样=====>要用明文传输密码文件完整性校验 不能由hash值返解成内容=======>把密码做成hash值，不应该在网络传输明文密码 只要使用的hash算法不变，无论校验的内容有多大，得到的hash值长度是固定的 理解:hash算法就像是一座工厂,工厂接收你送来的原材料(可以使用,.update()为工厂运送原材料). 经过加工返回的产品就是hash值. # --------------------示例--------------------------------------> import hashlib m = hashlib.md5() m.update('hello'.encode()) print(m.hexdigest()) # 5d41402abc4b2a76b9719d911017c592 m.update('alvin'.encode()) print(m.hexdigest()) #

Python HMAC-SHA256 signature differs from PHP signature

由 我们两清 提交于 2019-12-24 14:17:56
问题 I searched and found a few questions that sort of addressed what I am trying to accomplish, but I can't seem to quite put my finger on this. I'm new to programming and am trying to replicate a bit of code that's available to me by the vendor in a handful of languages (PHP, Ruby, Perl, C#). I've taken the PHP code and tried my best to replicate it in Python and have gotten everything working except this signature function. Basically, I have to take an array of data that's being passed in by a

HMAC-SHA-512 implemention for ActionScript

由 丶灬走出姿态 提交于 2019-12-24 07:43:55
问题 As mentioned by the title, I would like to find an implementation for HMAC-SHA-512 written for ActionScript. I was able to find a library that provide HMAC-SHA-256 with other functions, however, I am looking for HMAC-SHA-512 specifically. Thank you Edit: Or, since actionscript and javascript have the same origin, can some one port this javascript version into actionscript? http://pajhome.org.uk/crypt/md5/sha512.html Edit 2: I already ported the code from javascript to actionscript. The code

I'm getting slightly different hmac signatures out of clojure and python

问题 The HMAC SHA1 signatures I'm getting from my python implementation and my clojure implementation are slightly different. I'm stumped as to what would cause that.

Accidental Complexity in OpenSSL HMAC functions

由 空扰寡人 提交于 2019-12-24 02:49:09
问题 SSL Documentation Analaysis This question is pertaining the usage of the HMAC routines in OpenSSL. Since Openssl documentation is a tad on the weak side in certain areas, profiling has revealed that using the: unsigned char *HMAC(const EVP_MD *evp_md, const void *key, int key_len, const unsigned char *d, int n, unsigned char *md, unsigned int *md_len); From here, shows 40% of my library runtime is devoted to creating and taking down HMAC_CTX 's behind the scenes. There are also two additional
