While hashing algorithms provide significant security benefits, they are not without limitations:
Collision: Different inputs may produce the same hash, known as a collision. While rare, this can compromise data integrity. Irreversibility: The one-way nature of hashing means that if the original data is lost, it cannot be retrieved from the hash. Computational Overheads: Stronger hashing algorithms require more computational resources, which can be a concern for large-scale email marketing operations.
