RSA-SHA1 Digest

[WCR]

Hi All

I have two simple questions that perhaps someone can answer.

        1.      Does Openssl version 0.9.8e allow one to produce an SHA1 digest 
with
RSA?
        2.      If so, can I do it from a command line or do I need to link the
libraries?

I think an SHA1 digest with RSA returns a string of length 28 Bytes but I
get 40 Bytes when I use the command:  openssl dgst -sha1 -key mykey.pem
mydata.txt > mydigest.out (I want 28 bytes)

Can anyone help samples etc?

TIA
David
