hmacsha1

My Company recently signed up for Google Maps API for business. To use the API, I need to generte a HMacSHA1 signature, and add it to my HTTP request. Unfortunately, somehow, I am not able to generate the right signature. For testing, I am using the values provided by google to ensure that the algorithm works fine and I get the right result. Here is the code: string url = 'maps/api/geocode/json?address=New+York&sensor=false&client=clientID'; string privateKey = 'vNIXE0xscrmjlyV-12Nj_BvUPaw='; privateKey = privateKey.replace('-', '+'); privateKey = privateKey.replace('_', '/'); //Blob

i try to coding HMAC-SHA256 Algorithm as Function HMAC (K,m) = H((K ⊕ opad) ∥ H((K ⊕ ipad) ∥ m)) where H is a cryptographic hash function, K is a secret key padded to the right with extra zeros to the input block size of the hash function, or the hash of the original key if it's longer than that block size, m is the message to be authenticated, ∥ denotes concatenation, ⊕ denotes exclusive or (XOR), opad is the outer padding (0x5c5c5c…5c5c, one-block-long hexadecimal constant), ipad is the inner padding(0x363636…3636, one-block-long hexadecimal constant). and this my code public static string

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center . Closed 6 years ago . I have a java code example to make a digest computed using the HMAC-SHA1 algorithm (RFC 2104.), then encoded using Base64 encoding (RFC 2045). here is the java code public static String buildDigest(String key, String idString) throws SignatureException { try { String algorithm = "HmacSHA1"; Charset charset =

I have been tasked with converting some existing piece of node.js code to Java. I think I'm well on my way, but I'm kind of stuck right now. The output of the methods do not seem to match. What I'm doing is creating a SHA-1 signature based on a query string. This query string contains some query-related data (not relevant for this question) and an API key. Important The api_secret string in node.js is equivalent to Config.API_SECRET in Java. Example query string (these are equal in the node.js and Java program): /events?festival=imaginate&pretty=1&size=100&from=0&key=SOME_KEY Actual code The

There is an example HMAC-SHA1 here that works in javascript http://jssha.sourceforge.net/ Text to encrypt vibaHBXwUXFqVSg-+kTrqYJZEJkbVeqLc=bo.LlXGET12505351831husu9039http://api.tineye.com/rest/search/image_url=http%3a%2f%2ftineye.com%2fimages%2ftineye_logo_big.png&limit=30&offset=10 Key vibaHBXwUXFqVSg-+kTrqYJZEJkbVeqLc=bo.LlX Output 9e734661c9e8b6dc9b6b4b3def9769c00e8843b8 Issue I can't however duplicate the output in Coldfusion.

I’m currently facing a big problem (Environment: .NET 4.5 Core): We need to protect a message with a key using a HMAC-SHA1 algorithm. The problem is that the HMACSHA1-class of the namespace System.Security.Cryptography and the namespace itself do not exist in .NET 4.5 Core, this namespace only exists in the normal version of .NET. I tried a lot of ways to find an equivalent namespace for our purpose but the only thing I found was Windows.Security.Cryptography which sadly does not offer a HMAC-Encryption. Does anyone have an idea how I could solve our problem or is there any free to use 3rd

Is there any function for creating Hmac256 string in android ? I am using php as my back end for my android application, in php we can create hmac256 string using the php function hash_hmac () [ ref ] is there any function like this in Android Please help me. Calculate the message digest with the hashing algorithm HMAC-SHA256 in the Android platform: private void generateHashWithHmac256(String message, String key) { try { final String hashingAlgorithm = "HmacSHA256"; //or "HmacSHA1", "HmacSHA512" byte[] bytes = hmac(hashingAlgorithm, key.getBytes(), message.getBytes()); final String
