Frequently Asked Questions
What is SHA-512?
SHA-512 (Secure Hash Algorithm 512-bit) is a cryptographic hash function that produces a fixed 512-bit (128-character hex) output. It is part of the SHA-2 family and offers a higher security margin than SHA-256.
Is SHA-512 better than SHA-256?
SHA-512 provides a larger output size and is generally considered more secure against brute-force attacks. However, for most practical applications, SHA-256 is sufficient. SHA-512 is recommended when maximum security is required.
Can SHA-512 be reversed?
No. Like all cryptographic hash functions, SHA-512 is one-way. You cannot recover the original input from its hash.
Is my data safe with this tool?
Yes. All hashing happens locally in your browser using the Web Crypto API. Your input is never sent to any server.
