# md5

md5() function is the Standard function available in 200OK.

**Description** : The fx\_md5 function computes the MD5 hash value of the input string, generating a 32-character hexadecimal representation. This cryptographic hash function is commonly used for data integrity verification and password storage.

**Syntax** : fx\_md5(string)

**Example** : applying fx\_md5('test') returns '098f6bcd4621d373cade4e832627b4f6'.

Here we go with simple scenario using the above function.

**Scenario** : In a file storage system, administrators verify file integrity by computing MD5 checksums. They use fx\_md5 to generate a unique hash value for each file, ensuring data integrity.
