I have this algorithm in Java to store passwords in database. I'd like to re-write my application in Ruby on Rails, so I need the same algorithm to compare hashed passwords. What's the Ruby equivalent of this algorithm? public static String encrypt(String password) { MessageDigest md; try { md = MessageDigest.getInstance("SHA"); m...
The following snippets are both supposed to calculate sha-1 sum. But for the same file they calculate different sha-1 sums. //snippet1 byte[] byteArr = new byte[(int) uploadedFile.getLength()]; try { stream = new BufferedInputStream(uploadedFile.getInputStream()); stream.read(byteArr); stream.close(); } catch (IOException e) { e.p...
Hi, I'll give you a little bit of background first as to why I'm asking this question: I am currently working in a stricly-regulated industry and as such our code is quite carefully looked-over by official test houses.

Hello everyone. In a WinForm application using C#.NET 2.0 (on Vista), I am using SHA1 hash to create a hash from a string and store the hash in a text file (with UTF-8 encoding). I want to use the hash stored in text file to in a condition. When I run the project in Vista it works properly (i.e. the condition results in true), but when I...

Hi, I'm writing a simple content management system. I need to store SHA1 hash values that are computed externally as the primary key for my biggest table. I can obviously use a sequence as a primary key and index the SHA1 hex-string for look-up... However, I'm looking for a more elegant solution, where I will simply use the 20-byte SHA1...
