Yes, this is special-cased in the EMSA3 / hash identifier code.
will produce an SSL-style signature.
Anywhere where a single hash can be used, you can use
"Parallel(X,Y,Z)" to use multiple concatenated hashes. (Random aside:
I wonder if anyone has looked at the security of HMAC when used with
In 1.9.7 a new method of combining hashes, Comb4P, that provides
additional useful security properties, was also added. (Though it can
only combine 2 hashes, and they must have the same output length).

And in OpenSSL there is a mechanism for SSL signatures, NID_md5_sha1 (MD5 and SHA1 message digests with PKCS #1 padding and no algorithm identifier). Is there a way that this can be done in Botan? Because you can only input one hash algorithm in the EMSA3 class.
