What is RSA key normalization? How can I understand the term RSA key normalization? What exactly is done in the process??
Please explain.
RSA key normalization is merely the convention that when comparing public keys we view them as two numbers where the first number is the public exponent and the second is the public modulus. Now in the case of RSA if you're given the public key as two numbers then the big composite one is the modulus and the smaller one which is often 65537 is the exponent so it's pretty obvious which is which.

The need for normalization is more obvious with DSA keys which involve four numbers of which two (the generator and the public value) would be impossible to distinguish if $h$ was chosen at random when the generator $g=h^{(p–1)/q)}$ was calculated). In all cases with DSA if you're just given the four parameters in any order you have to do a bit of extra calculation to make sense of it and normalization takes care of the whole issue.
