# sha1

sha1() function is the Standard function available in 200OK.

**Description** : The fx\_sha1 function calculates the SHA1 hash of the input string, producing a 40-character hexadecimal representation. This cryptographic hash function is widely used for data integrity verification and secure authentication.

**Syntax** : fx\_sha1(string)

**Example** : when applied to the string 'string', fx\_sha1('string') returns 'ecb252044b5ea0f679ee78ec1a12904739e2904d'.

Here we go with simple scenario using the above function.

**Scenario** : In cybersecurity, protecting sensitive data is critical. Through encryption techniques, information is secured from unauthorized access. Using a hashing algorithm, input strings are transformed into unique hash values, ensuring data integrity.
