Assume that you are using a cryptographic hash algorithm that produces output or

signatures that are $2128$ bits in length. How long will the output or signature be if the input

is a single digit?

a$.2$

$128$ bits

b$.$ The hash algorithm will not be able to perform calculations on any input larger

than $2128$ bits.

c$.$ The hash output or hash signature will contain $1$ bit for each $128-$bit block of

input.

d$.$ The same size as the input plus $128$ bits.

e$.$ More information is required to make this determination.
