About Cryptographic Hash Functions

Cryptographic hash functions convert data of any size into a fixed-size string of characters. The output is unique to the input, making hashes useful for data integrity verification and password storage.

Algorithm Security:

  • • MD5: Deprecated, use for checksums only
  • • SHA-1: Deprecated, legacy support
  • • SHA-256: Secure, recommended
  • • SHA-512: Most secure, slowest

Common Use Cases:

  • • File integrity verification
  • • Password hashing (with salt)
  • • Digital signatures
  • • Data deduplication

What is a Hash Generator?

A hash generator creates cryptographic hash values from text using MD5, SHA-1, SHA-256, or SHA-512. Hashing is a one-way process used for verifying file integrity, storing password digests, and creating data fingerprints. All processing uses the Web Crypto API in your browser.

Frequently Asked Questions

Which algorithm should I use?

SHA-256 for most purposes. MD5 and SHA-1 are weak for security but acceptable for checksums.

Can I reverse a hash?

No. Hash functions are one-way by design.

Is MD5 safe?

Not for security. It is cryptographically broken but still used for non-security checksums.
