I have to generate sha256 hashes of data that is in little endian form. I would like to know if I have to convert it to big endian first, before using the sha 256 algorithm. Or if, the algorithm is \"
when I call getwork on my bitcoind server, I get the following: ./bitcoind getwork { \"midstate\" : \"695d56ae173bbd0fd5f51d8f7753438b940b7cdd61eb62039036acd1af5e51e3\",
Is there a simple library out there for Java in a Maven repository that will gi开发者_StackOverflowve me simple, one-liner hash methods for the popular hash functions such as MD5, SHA1, SHA256, and SH
This is the code #include <stdbool.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h>
I need an example of how to use Crypto++ to generate a SHA256 hash from a std::string and output a std::string. I can\'t seem to figure it out. Everything I\'ve tried gives me invalid output.
Say I have a Float. I want the first 32 bits of the fractional part of this Float? Specifically, I am looking at getting this part of the sha256 pseudo-code working (from the wikipedia)
If I kn开发者_开发知识库ow the hashes of two (or more) parts of some data, can I calculate the hash of the full data from those hashes?
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
Newbie here. I\'m trying to encrypt the user password using SHA-256 after they\'ve made their account and then when the user tries to log in, it will try to match their input with any of the encrypted
