问题 The following is the error I am getting: no matching mac found: client hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@openssh.com,hmac-sha1-96,hmac-md5-96 server hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-512,hmac-sha2-256,umac-128@openssh.com 回答1: You are getting this error because the client and the server could not agree upon a hashing algorithm for message authentication code.

问题 I'm querying an API that uses OAuth1. I can make a query successfully using RestSharp: var client = new RestClient("https://api.thirdparty.com/1/"); client.Authenticator = OAuth1Authenticator.ForAccessToken(appKey, appSecret, token, tokenSecret); var request = new RestRequest("projects/12345/documents", Method.GET); request.AddParameter("recursive", "true"); var response = client.Execute(request); Unfortunately I'm unable to use RestSharp in the actual project (I'm just using it here to

问题 I'm tasked with building a consumer of an API that requires an encrypted token with a seed value that is the UNIX time. The example I was shown was implemented using Java which I'm unfamiliar with, and after reading through documentation and other stack articles have been unable to find a solution. Using the javax.crypto.SecretKey , javax.crypto.SecretKeyFactory , javax.crypto.spec.PBEKeySpec , and javax.crypto.spec.SecretKeySpec protocols, I need to generate a token similar to the below:

问题 I want to crypt privateKey & publicKey to sha1 in base64 with Swift, but the output is not the one I see in PHP urlencode base64_encode which I tried in Codecademy:"https://www.codecademy.com/courses/web-beginner-en-StaFQ/0/3?curriculum_id=5124ef4c78d510dd89003eb8". Pls see the following codes in Swift and Codecademy: Swift: //pls see func dataFromHexadecimalString() details here "http://stackoverflow.com/questions/26501276/convert-string-to-hex-string-in-swift/26502285#26502285" extension

问题 All of this is new to me so please forgive my noobish question. I'm trying to figure out HMAC step by step. Let's say I have a following SHA-1 method: public static string SHA_1(string input) { SHA1CryptoServiceProvider mySha = new SHA1CryptoServiceProvider(); string temp = BitConverter.ToString(mySha.ComputeHash(Encoding.UTF8.GetBytes(input))); temp = temp.Replace("-", "").ToUpper(); return temp; } It receives a plain text string; Let's say my secret key is "" (empty string) and so is the

问题 I am trying something a little specific, namely trying to call a REST API. I have been following these instructions. I have been very careful to ensure that I am creating the "Signature base string" correctly. They define it to be created like this: (HTTP Method)&(Request URL)&(Normalized Parameters) You can double check if need be in my code, but I am very sure that it is fine. The problem that I am having is creating what they call the "oauth signature" and mine isn't matching theirs. They

问题 Concerning OAuth, what is the most suitable cryptography/encryption method to use HMAC-SHA1 or RSA-SHA1 ? Thanks. 回答1: After looking, it's seems that HMAC is much faster and better in term of security even if the underlying hash function (SHA1) is broken, which is not the case when using RSA-SHA1. 回答2: In cryptography you normally go for a symmetric scheme - such as HMAC - over an asymmetric scheme - such as RSA for signing - if that is possible within the protocol. In general asymmetric

问题 I am developing a large application and i need encryption when a data is traveling between two machines in different continents. I have never worked on encryption. I want a simple encryption which can be handled in PHP / Ruby / Python without any dependencies. So i decided to use HMAC SHA1. $pad=hash_hmac("sha1","The quick brown....","mykey"); This is what i found out after some research on the internet. How hard it is to decrypt it if someone doesn't know the key? Also, any alternatives to

问题 I'm using the code below with the Crypto API and I'm not getting the results I would expect based on testing with other API's and libraries. I'm using the key, " key " and the data is " message " For example, using Indy's TidHMACSHA1, I get 2088df74d5f2146b48146caf4965377e9d0be3a4 I get the same result using online generators (such as http://www.freeformatter.com/hmac-generator.html, for example). With the code I've written (see below) I get 4a52c3c0abc0a06049d1ab648bb4057e3ff5f359 The code

问题 I'm trying to setup some Google Maps Premier API action, and to do so, I need to sign my URLs to authenticate. If you go down to Signature examples, there is some Python, C# and Java code to show you how to do the signature via HMAC-SHA1. There is also an example so that I can to test my PHP implementation. However, I just can't seem to get it to work. Here's my code: $key = "vNIXE0xscrmjlyV-12Nj_BvUPaw="; $data = "/maps/api/geocode/json?address=New+York&sensor=false&client=clientID"; $my
