comment Signature algorithm SHA 1-2 with ECDSA
I am using a third Party HSM. Btw, the thing about it working for keysizes 224 and above is not fully true. I tried to generate various keysizes(even 32 bit and 20 bit) and for all These Input key sizes, ECDSA SHA1 seems to work..is this wrong behaviour?

ok, the SHA1 ECDSA seems to accept from key size 224 onwards..

Can you Elaborate on the use of one master key? At the Moment I have this crypto library that is a Blackbox to me and when I fed a 128 bit AES key and choose AES with HMAC Sha1 it works. The same Routine seems to also work with a 160 bit key. So I am a bit lost.

comment What does an RSA signature look like?
Ok, I am just going through the OpenSSL source codes. I think what I understood is that the hash of the message is computed, it is converted to an X509_SIG object which is then passed to RSA_private_encrypt(isn't this 'private key' encryption?) along with the PKCS#1 as padding info. What is then happening differently??

"The value x is raised to the power d (private exponent) modulo n, yielding s=xd(modn)." Is this where the key is used? Is this operation equivalent to RSA private key encryption?

yes you are right. It is indeed 0x10001 in OpenSSL case.
