Suppose you receive a digital certificate that contains M and[h(M)]CA , where M = (Alice, Alice's public key) and\"CA\" is a Certificate Authority.
How do you verify the Signature?
Remember that:
[X]Bob indicates encryption via Bob's private key toX (signature)
h(X) indicates the cryptographic hash function applied to X
Group of answer choices
You decrypt the encrypted message using the CA's public key,then you compute the hash of [h(M)]CA, finally youcompare the two hashes
You decrypt the encrypted message using the CA's private key,then you compute the hash of [h(M)]CA, finally youcompare the two hashes
You decrypt the encrypted message using the CA's private key,then you compute the hash of M, finally you compare the twohashes
You decrypt the encrypted message using the CA's public key,then you compute the hash of M, finally you compare the twohashes
