SHA-1 produces a(n) 160-bit message digest, which can then be used as an input to a digital signature algorithm.
Secure Hash Algorithm 1 or SHA 1 is a function which take the input value. In the result, it produces the hash value of 20 byte.
As there is 8 bit in 1 byte. Thus, the number of bits in 20 byte are,
[tex]n=20\times8\\n=160\rm\; bits[/tex]
Hence, it produces 160 bit of hash value, which is known as the massage digest.
Thus, SHA-1 produces a(n) 160-bit message digest, which can then be used as an input to a digital signature algorithm.
