Function text_hash

ms_agent/utils/utils.py:261–288

Encodes a given text using SHA256 and returns the last 8 characters of the hexadecimal representation. Args: text (str): The input string to be encoded. keep_n_chars (int): The number of characters to keep from the end of the hash. Returns: str: The last 8
