There is no equivalent utility to "rsautl" for DSA keys. The equivalent functionality is in "pkeyutl" but that is only present in OpenSSL 0.9.9-dev. You don't normally sign raw data with a private key anyway. Normally the data is digested and the digest is signed. There is a utility to perform the combined digest+sign (and digest+verify) function: it is 'dgst'. Steve. -- Dr Stephen N. Henson.
