SHA-512 Hash Generator
Computed in your browser — your text is never sent to a server.
What is SHA-512 Hash Generator
SHA-512 (Secure Hash Algorithm 512-bit) is part of the SHA-2 family, published by NIST in 2001. It produces a 128-character hexadecimal string (512 bits) — the longest output of the common SHA-2 variants. SHA-512 provides a larger security margin than SHA-256, is faster than SHA-256 on 64-bit CPUs, and is used in high-security applications such as TLS certificate chains, digital forensics, and password hashing schemes like PBKDF2. This tool computes SHA-512 hashes entirely in your browser using the native Web Crypto API.
How to use
- Type or paste any text into the input field.
- The SHA-512 hash updates instantly as you type.
- Click Copy to copy the 128-character hash to your clipboard.
- To switch to another algorithm, choose MD5, SHA-1, or SHA-256 from the Algorithm dropdown — your input is preserved.
When to use it
Need a tamper-evident record of a production database backup? Hash the file with SHA-512 and save the 128-character result. Before you restore, recompute the hash and compare it to the saved value: any bit-level corruption or unauthorized change produces a completely different string, so you catch the problem before it spreads.
Frequently asked questions
Is SHA-512 more secure than SHA-256?
SHA-512 offers a larger security margin (512 vs 256 bits), making it more resistant to brute-force attacks. Both are currently considered secure, but SHA-512 is preferred for extremely high-security scenarios.
How long is a SHA-512 hash?
SHA-512 produces a 512-bit value displayed as 128 hexadecimal characters, regardless of the input size.
Is SHA-512 faster than SHA-256?
On 64-bit CPUs, SHA-512 is often faster than SHA-256 because it processes data in 64-bit words instead of 32-bit words, processing more data per clock cycle.
Is my text sent to a server?
No. SHA-512 is computed in your browser using the Web Crypto API. Your input never leaves your device.
Can I share this tool with my inputs pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Share button — anyone who opens the link will see your exact inputs ready to go.
