How can I create a SHA1 from a NSString. Let\'s say the NSString is set up as: NSString *message 开发者_StackOverflow= @\"Message\";
Someone asked me if I can help them out with a small project. Everything was working out perfect until I ran into an SHA-1 encryption. I have been working on it for several days but cannot figure out

I am just messing around with simple hashing be开发者_StackOverflowcause I am new to the idea, and I have the following:
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...
I have a NSString representing sha1 hash of some data and I need to convert it to binary string, but cant find any good sol开发者_如何学Cution to do that. It should be equivalent to PHP\'s pack functi
So, I found out on SO that you\'re supposed to hash the password together with a \"salt\". (The articles can be fo开发者_运维百科und here and here.)
import java.security.MessageDigest; class Enc{ public String encryptPassword(String password) throws Exception{
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\";\'
The SHA1 hashes stored in the tree objects (as returned by git ls-tree) do not match the SHA1 hashes of the file content (as returned by sha1sum):
