SHA512 Generator
Generate SHA-512 hashes from any text — instant SHA-512 hash calculation in your browser.
SHA-512 provides 512 bits of output and is slightly faster than SHA-256 on 64-bit systems.
About SHA-512
A cryptographic hash function takes an input of any length and produces a fixed-length output (digest) that uniquely represents the input. Even a single character change produces a completely different hash — this is called the avalanche effect. Hash functions are one-way: you cannot reverse a hash to get the original input.
SHA-512 is used for data integrity verification (checksums for file downloads), digital signatures, certificate generation, and (for SHA-256/SHA-512) password hashing when combined with a salt. This tool computes hashes in your browser using the Web Crypto API — no data is sent to any server.
FAQ
Can I use SHA-512 to store passwords?
No. SHA-512, while strong, is too fast for password hashing. Use bcrypt, Argon2, or scrypt which are deliberately slow and memory-hard.
What is the difference between encoding and hashing?
Encoding (Base64, URL encoding) is reversible — you can recover the original data. Hashing is one-way — you cannot recover the input from the hash. Use encoding when you need to store and retrieve data. Use hashing when you only need to verify data without storing it.
