sha1

Hi,

I have this method to hash a string:

 byte[] buffer = enc.GetBytes(text);
 SHA1CryptoServiceProvider cryptoTransformSHA1 =
                new SHA1CryptoServiceProvider();
 string hash = BitConverter.ToString(
                cryptoTransformSHA1.ComputeHash(buffer)).Replace("-", "");

 return hash;

My question is:

Is the resulting hash always the same for the same string?

I hashed a string a couple of days ago and it seems that it now resulted in another hash, but i'm not sure.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

Is it possible to get identical SHA1 hash?

as seen on Stack Overflow - Search for 'Stack Overflow'
Given two different strings S1 and S2 (S1 != S2) is it possible that: SHA1(S1) == SHA1(S2) is True? If yes - with what probability? Is there a upper bound on the length of a string, for which probably of getting duplicates is 0? If not - why not? Thanks >>> More

Is there any difference between md5 and sha1 in this situation?

as seen on Stack Overflow - Search for 'Stack Overflow'
It is known that 1. if ( md5(a) == md5(b) ) 2. then ( md5(a.z) == md5(b.z) ) 3. but ( md5(z.a) != md5(z.b) ) where the dots concatenate the strings. What happens in the second row if we change all the md5 to sha1? So: 1. if ( sha1(c) == sha1(d) ) 2. then ( sha1(c.z)… >>> More
