Class Method Details

.md5(filename) ⇒ String

Computes the MD5 hash digest for a given file.

This method reads the entire contents of the specified file in binary mode and calculates its MD5 hash value. It uses a configurable buffer size for reading the file in chunks to optimize memory usage during the hashing process.

Parameters:

  • filename (String) —

    the path to the file for which to compute the MD5 hash

Returns:

  • (String) —

    the hexadecimal representation of the MD5 hash digest
