Bug Fix(es):

The RSAPSSSignature implementation works with RSA keys via the SunRSASign provider. However, it did not fully check that the RSA key could be used by the provider before attempting to do so, leading to the possibility of errors being returned with custom security providers. The implementation now validates RSA keys and will allow other providers to handle such keys where it cannot. (RHBZ#2188025)
