- What hash algorithms are supported?
- This tool supports SHA-1, SHA-256, SHA-384, and SHA-512. All hashing is performed locally in your browser using the Web Crypto API — your data is never sent to a server.
- What is the difference between SHA-256 and SHA-512?
- SHA-256 produces a 256-bit (64-character hex) hash, while SHA-512 produces a 512-bit (128-character hex) hash. SHA-512 offers a larger output space and is often faster on 64-bit processors, but both are considered cryptographically secure.
- Is SHA-1 still safe to use?
- SHA-1 is considered cryptographically broken for collision resistance and should not be used for security purposes like digital signatures or certificates. It is still acceptable for non-security uses such as checksums and data deduplication.
