Secure hash algorithms

Always use cryptographically secure hash algorithms for sensitive operations instead of weak or broken ones. Weak algorithms can compromise security and make your application vulnerable. Prefer modern algorithms like SHA-256 over older or non-cryptographic hash functions.

When selecting a hashing algorithm, consider both security requirements and performance implications. As demonstrated in the benchmarks, sometimes the more secure option may also offer better performance:

// Avoid using weak hashing algorithms
// AVOID: return xxh32(value).toString();

// PREFER: Use cryptographically secure algorithms
return createHash('sha256').update(value).digest('hex');

Note that non-cryptographic hash functions (like xxhash) are designed for speed and collision resistance in data structures, but not for security purposes where resistance to attacks is required.
