Frequently Asked Questions
What is SHA-512?
SHA-512 produces a 512-bit (128-character hexadecimal) hash. It is part of the SHA-2 family and provides a higher security margin than SHA-256. It is actually faster than SHA-256 on 64-bit processors due to native 64-bit operations.
When should I use SHA-512 instead of SHA-256?
Use SHA-512 when you need a larger hash output (e.g., for key derivation), when running on 64-bit systems (it is faster), or when your security policy requires the highest available hash strength. For most purposes, SHA-256 is sufficient.
How does SHA-512 performance compare to SHA-256?
On 64-bit processors, SHA-512 is typically 30-50% faster than SHA-256 because it uses 64-bit operations natively. On 32-bit systems, SHA-256 is faster. Both are significantly faster than bcrypt or Argon2 (by design).
Can I generate a SHA-512 hash of a file?
Yes. Upload any file and the generator computes its SHA-512 checksum. The 128-character output provides extremely high collision resistance. File hashing happens entirely in your browser for privacy.
What is SHA-512/256?
SHA-512/256 runs the SHA-512 algorithm but truncates the output to 256 bits. It combines SHA-512's speed on 64-bit systems with SHA-256's output size. It also resists length extension attacks that affect plain SHA-256.
