I'd be surprised if PKCS#1 v2.0 introduced incompatibilities with the
previous version. At any rate, RFC 4871 says: "
3.3.1. The rsa-sha1 Signing Algorithm
The rsa-sha1 Signing Algorithm computes a message hash as described
in Section 3.7 below using SHA-1 [FIPS.180-2.2002] as the hash-alg.
That hash is then signed by the signer using the RSA algorithm
(defined in PKCS#1 version 1.5 [RFC3447]) as the crypt-alg and the
signer's private key. [...]"
