The Secure Hash Algorithm (SHA-1) of the Secure Hash Standard (NIST FIPS PUB 180) processes data
in block lengths of:
A.
128 bits.
B.
256 bits.
C.
512 bits.
D.
1024 bits.
Explanation:
The correct answer is 512 bits. If a block length is fewer than 512 bits, padding bits are added to
make the block length equal to 512 bits. The other answers are distracters.
