verifying rsa signatures

[Chandrasekhar I.V.]

Does gnupg-1.0.6 have the support for verifying signatures generated
thru RSA encryption of SHA1 hases?
I dont see how i can specify a RSA public key to verify a digital
signature generated by RSA. "gpg --import" doesnt allow me to import RSA
public keys. My "gpg --version" however shows "PubKey RSA,...."
Also the "gpg --gen-key" shows me no "RSA"option for the kind of key i
want! ( i see only DSA&ElGamal, DSA and ElGamal options).
The gnupg faq however says that RSA is included frm gnupg-1.0.3 and
above versions!

Anyone can help me out?

thanks
sekhar.
