Hash collisions occur when two different inputs produce the same hash value, which can lead to data integrity issues in systems like databases or cryptographic protocols. Proper handling is critical to maintain reliability and security.

Common Solutions

  • Chaining Method
    Use linked lists to store collided entries.

    hash_collision_handling

  • Open Addressing
    Resolve collisions by probing for the next available slot in the hash table.

    collision_resolution

  • Salted Hashing
    Add a unique salt value to inputs to minimize collision risks.

Best Practices

  • Always validate input data before processing.
  • Use strong hashing algorithms (e.g., SHA-256) for cryptographic purposes.
  • Regularly update collision detection mechanisms to adapt to new threats.
