Subject: unexpected behavior of indexing / .length

first I have:

signature = Base64.encode64(@stored_priv_key.dsa_sign_asn1(message))
puts "first signature length is #{signature.length}"

=> first signature length is 78

then later in a different method I have

signature = decrypted[0,77]
puts "second signature length is #{signature.length}"

=> signature length is 77


Now I can get this to work by making the range [0,78] (which returns a
78 character string)

but it seems like it is not starting from 0 which is not the expected
behavior. Even though it works when I make the range 0,78 it is not how
it is supposed to be as far as I can tell, because it should be starting
at 0 which counts for length 1 and then going up to position 77 which
counts for 77 other additions to length in addition to the first 0.

I don't have ALL of my code here and maybe you need to see it all, but
what could ever cause the behavior or an indexed range creating a length
that is as large as the largest number in the range (instead of +1,
taking the 0 position into account)
