What Is SHA-512 Hashing?
SHA-512 is a member of the SHA-2 family of cryptographic hash functions. It produces a 512-bit (64-byte) hash value, rendered as a 128-character hexadecimal string. SHA-512 offers the highest security margin among the SHA-2 variants and is widely used in applications requiring strong data integrity.
SHA-512 operates on 64-bit words, making it faster than SHA-256 on 64-bit processors. It is used in digital signatures, TLS handshakes, and password hashing schemes. Research into its security properties is discussed in this cryptographic analysis paper. This tool computes the SHA-512 hash of your entire input using the Web Crypto API.

Frequently Asked Questions
Is SHA-512 more secure than SHA-256?
Both SHA-256 and SHA-512 are considered secure. SHA-512 provides a larger hash output (512 bits vs 256 bits), offering a higher security margin against brute-force attacks. For recommended key lengths and algorithm strengths, see keylength.com.
When should I use SHA-512 over SHA-256?
Use SHA-512 when you need a larger hash output or when running on 64-bit systems where SHA-512 can be faster. SHA-512 is also common in password hashing (e.g., Linux crypt) and high-security applications.
Can I compute SHA-512 in Python?
Yes. Python's standard library includes SHA-512 support via the hashlib module: import hashlib; hashlib.sha512(b"Hello").hexdigest().
Is my data sent to a server?
No. All hashing is performed locally in your browser using the Web Crypto API. No data ever leaves your machine.
