Free online SHA-256/512 hash generator tool, processed locally
What is SHA-256 and SHA-512?
SHA-256 and SHA-512 are members of the SHA-2 family of cryptographic hash functions designed by the NSA. SHA-256 produces a 256-bit (32-byte) hash displayed as 64 hex characters. SHA-512 produces a 512-bit (64-byte) hash displayed as 128 hex characters. Both are widely used in security protocols, digital signatures, and blockchain technology.
How to Generate a SHA Hash
Enter your text in the input area. The tool generates both SHA-256 and SHA-512 hashes simultaneously. Copy either result with one click. All computation runs in your browser using the Web Crypto API.
When to Use SHA-256 vs SHA-512
SHA-256 is the most widely adopted and is used in TLS certificates, SSH, Bitcoin, and most web security protocols. SHA-512 is stronger and faster on 64-bit platforms. For most applications, SHA-256 provides sufficient security.
