Pro Tips

  • 💡SHA-256 is recommended for most security applications.
  • 💡MD5 and SHA-1 are considered weak - avoid for security purposes.
  • 💡Same input always produces the same hash (deterministic).
  • 💡Even tiny changes in input produce completely different hashes.

Frequently Asked Questions

What is a hash function?
A hash function takes input data and produces a fixed-size string of characters (the hash). It's one-way - you can't reverse a hash to get the original data.
Is MD5 secure?
No, MD5 is cryptographically broken and should not be used for security purposes. It's still useful for checksums and non-security applications.
Which hash algorithm should I use?
For security, use SHA-256 or SHA-512. For simple checksums where security isn't critical, MD5 is faster but less secure.
Can two different inputs produce the same hash?
Theoretically yes (called a collision), but for secure algorithms like SHA-256, finding collisions is computationally infeasible.
