Temporary File Manipulation and Hashing Process

The function first creates a temporary file and writes the first argument to it. Then, it uses regular expressions to find numbers in the second argument and performs a SHA-256 hash on the first found number, appending the result to the file. If no numbers are found, it appends 'No numbers found.' to the file. Then, it simulates a delay of 2 seconds. It encodes the file content using base64 and appends the encoded content to the file. Finally, it deletes the created temporary file.
