Is my text sent to a server?

No. All hashing happens entirely in your browser using the built-in WebCrypto API. Your text never leaves your device.

SHA-384 is a member of the SHA-2 family of cryptographic hash functions. It produces a 384-bit (48-byte) digest, represented as 96 hexadecimal characters. It is widely used in TLS certificates, digital signatures, and Subresource Integrity checks.

How is SHA-384 different from SHA-256?

SHA-384 produces a longer 384-bit digest compared to SHA-256's 256-bit digest, offering a larger security margin against collision attacks. SHA-384 is preferred when stronger security is required and output size is not a constraint.

Can I hash a file with this tool?

This tool hashes text input. To hash a file, you can read its contents and paste them here, or use a dedicated file hash tool.

What is the Base64 output used for?

Base64-encoded SHA-384 hashes are commonly used in HTTP headers such as Content-Security-Policy and the integrity attribute of script and link tags (Subresource Integrity / SRI).
