Let p1 and p2 be pointers to buffers formatted as described previously representing the first and second flows of the key negotiation. In the previous problem you assembled and hashed the concatenation of all of p1 followed by all of p2 up to and including X but excluding Auth_B. The data Auth_B purportedly contains Bobs RSA signature of this hash. Write a function int flow12_authb_verify(void *p1, void *p2) that returns 0 if the signature does not verify and non-zero if it does verify. To verify an RSA signature, you raise the signature to the public exponent (mod the modulus), which should evaluate to the thing that was signed. If the result is the same number as the hash, then the hash (and therefore the data) is verified. Bobs public key will be given in the C starter code in hex. You will have to call BN_hex2bn in order to convert it to a BIGNUM. To use BN_hex2bn you allocate a BIGNUM, which returns a pointer bn, and then you pass a pointer to this pointer: BN_hex2bn(&bn, hexstring). You will need to allocate and free your BIGNUMs in this problem. You will also need to allocate and free a BN_CTX.

This element exists in adundance in the sun. explain how you would go about capturing sunlight. would this captured sunlight contain any of the element?

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
