I am trying to make use of a REST API using C#. T开发者_开发问答he API creator has provided sample libraries in PHP, Ruby and Java. I am getting hung up on one part of it where I need to generate an H
I\'m designing a web service that clients connect to in order to retrieve some private data. Each client has a unique ID and a secret key (generated by the server) that are sent as parameters to the w
I\'m considering using Data::UUID Perl module to generate a 256 bit symmetric key for use with the HMAC_SHA256 algorithm. Each call should give me a unique string of 128 bits so I\'m thinking of doing
I\'m planning to use code similar to Amazon AWS samples to authenticate signed API requests. So users will have something like:
I am trying to login to my server using hmac sha256 encryption, i have working code in php, but can\'t get it working in iphone and traced it to that the hmac in iphone is yielding different output to
I am writing an application that heavily uses cryptology.Like most networked applications, mine breaks up data into different types of messages (instant message, file chunk, video frame, etc.) -- and
I\'m writing a module for Amazon开发者_如何学JAVA\'s SimpleDB. They require REST requests to be signed using HMAC-SHA algorithm. (Details here.)
Reading this excellent answer about password hashing and wondering how to implement it: The Wicked Flea wrote:
There are test vectors for PBKDF2-HMAC-SHA1 in RFC6070. There are test vectors for HMAC-SHA2 in RFC4231.
Can anyone point out what the advantage of using HMАC is? For example, if I have a text T and a key K, 开发者_Go百科I can use either HMAC-MD5 algorithm or Md5(T + K) to get a signature. HMAC is not
