Does Signature class expect plain text only or message digest?

Theoritically, signing operation includes the following steps

1. Create Hash of message called Message Digest.

2. Encryption of Hash.

My query is:

Does Signature class expect plain text (in byte[] ) only?

or I need to explicitly create a Message digest first and then pass it to Signature class.

You just pass the 'plain text', the appropriate key and, when verifying, the signature to verify. Everything else is done for you.

Thanks for verification.

I was having the same opinion until I saw some code which was creating explicitly hash and passing that to Signature class.
