The sha1() function in PHP is used to calculate the sha1 hash of a string. Let us first see what is SHA-1 −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. Signing the message digest rather than the message often improves the efficiency of the process because the message digest is usually much smaller in size than the message. The same hash algorithm must be used by the verifier of a ... Read More
