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: ```typescript // 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.
