Iam having a fun time with implementing SHA1 and HMAC methods in a iPhone Applecation. I need to access a webservice(which i do not controll) and they require both SHA1 and HMAC encryption.
I had to implement Password Reset policy....For which I had OpenSSO deployed on Glassfish server and OpenDS as the Data Store...I followed Indira\'s blog...
This HMACSHA1 code below works for converting \"Password\" and \"Message\" to AFF791FA574D564C83F6456CC198CBD316949DC9 as evidence by http://buchananweb.co.uk/security01.aspx.
First of all I am showing the code for my c file .. #include <stdlib.h> #include <sys/types.h>
Creating an HMAC steps by using CryptoAPI found here: http://msdn.microsoft.com/en-us/library/Aa379863
I am using this class in MSVC++ 2010 Express: http://www.codeproject.com/KB/recipes/HMACSHA1class.aspx.I am running Vista 32bit.Pretty much to get it working I just changed...
Say I\'m designing a library to sign/verify messages with SHA-256 HMAC. If the end user uses a weak开发者_C百科 shared key and sends a lot of short messages, I assume there would be risk of an attacke
i need to reproduce in python what perl does # perl perl -e\'use Digest::HMAC_SHA1 qw(hmac_sha1_hex); my $hmac = hmac_sha1_hex(\"string1\", \"string2\"); print $hmac . \"\\n\";\'
I\'m trying to quickly get a buggy .Net client library for a third party service I\'m using to work. The original library (which works) is written in Ruby, but their equivalent library for DotNet prod
If I use HMACSHA256.ComputeHash in my password encoding scheme and generate password hashes on one server then later need to migrate to a different server, will my hashes still encode the same? I reca
