How many bits encryption does SHA-1 use?

The correct answer is C. 160 bits. 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.
