SHA-1 is a hash algorithm, a critical component of secure cryptography. A hash algorithm takes a block of data as input and outputs a value of a certain size (SHA-1 hashes are 160 bits long). This value is called a hash or digest. With a good hash algorithm, two different blocks of data will always produce a different hash, and even a small change in the input data will result in a significant change in the output. There should be no way to learn anything about the input data from the hash output.
