How many bits encryption does SHA-1 use?
A.
64 bits
B.
128 bits
C.
160 bits
D.
256 bits
Explanation:
SHA-1 (as well as SHA-0) produces a 160-bit digest from a message with a maximum length of 264 – 1 bits, and is based on principles similar to those used by Professor Ronald L. Rivest of MIT in the design of the MD4 and MD5 message digest algorithms.
