sha1

I'm planning on storing the passwords as a sha1, so I need a way to validate that it is a sha1 at another point in my website. I was planning on using preg_match, but I do not know how to make regex patterns. Could someone help me out with one?

Thanks

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

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
