SHA-512 Hash Generator
Generate SHA-512 hashes from any text or file directly in your browser. SHA-512 produces a 512-bit (128-character hex) digest — the largest in the SHA-2 family. It's faster than SHA-256 on 64-bit systems and provides the highest security margin available.
Frequently Asked Questions
›Is SHA-512 more secure than SHA-256?
Both are considered cryptographically secure with no known practical attacks. SHA-512 has a higher security margin (256-bit collision resistance vs 128-bit), but for most applications SHA-256 is sufficient. SHA-512 can actually be faster on 64-bit CPUs.
›How long is a SHA-512 hash?
A SHA-512 hash is always 512 bits, which is 128 hexadecimal characters or 88 Base64 characters.
›Does this work with files?
Yes. You can hash files of any size by clicking the File button. The file is read and hashed entirely in your browser — it never leaves your device.
