SHA-1 or SHA1 is a one-way hash function; it computes a 160-bit message digest. SHA-1 often appears in security protocols; for example, many HTTPS websites use RSA with SHA-1 to secure their connections. BitTorrent uses SHA-1 to verify downloads.

Definition and Usage. The sha1() function calculates the SHA-1 hash of a string. The sha1() function uses the US Secure Hash Algorithm 1. From RFC 3174 – The US Secure Hash Algorithm 1: “SHA-1 produces a 160-bit output called a message digest.The message digest can then, for example, be input to a signature algorithm which generates or verifies the signature for the message.
