Can you explain what the term 'cryptographically secure hash' means and what its fundamental features are?

A cryptographically resistant hash is a hash function that possesses properties making it resistant to cryptographic attacks. Key features:

• One-wayness: it is impossible to recover the original data from the hash value.
• Collision resistance: it is extremely difficult to find two different input values that produce the same hash.
• Pre-image resistance: it is impossible to find an input that corresponds to a given hash.

Such properties are important for security, for example, in password storage, digital signatures, and data integrity verification.
