check if rsa public exponent is odd and check its value is between 2^16 < e < 2^256. FIPS 186-5 DSS (page 35)[1] specify that: 1. The public exponent e shall be selected with the following constraints: (a) The public verification exponent e shall be selected prior to generating the primes, p and q, and the private signature exponent d. (b) The exponent e shall be an odd positive integer such that: 2^16 < e < 2^256.
