About Hash Generator (Web Crypto)

The Hash Generator utilizes the browser native crypto.subtle.digest() API to compute irreversible cryptographic hash digests for data integrity and checksum verification. Only algorithms supported by the browser Web Crypto engine are offered.

Frequently Asked Questions

Which hashing algorithms are supported by this tool?

This tool supports SHA-256, SHA-384, SHA-512, and SHA-1 directly via the browser native Web Crypto API (crypto.subtle.digest). Legacy algorithms like MD5 and non-standard functions are intentionally excluded.

Why is MD5 not available in this generator?

MD5 is cryptographically broken due to well-known collision vulnerabilities and is not part of modern W3C Web Crypto standards. For integrity verification and security, SHA-256 or SHA-512 is recommended.

Are my inputs sent to any remote server?

No. All hash digests are computed entirely inside your browser hardware using the native Web Crypto API. No string or file content is ever transmitted.

Can cryptographic hashes be decrypted back into plain text?

No. Cryptographic hashes are one-way mathematical functions. You cannot reverse a hash back to its original input, though precomputed rainbow tables can look up common dictionary passwords.

What is the difference between SHA-256 and SHA-512?

SHA-256 produces a 256-bit (64 hex character) digest and is the industry standard for SSL certificates and blockchains. SHA-512 produces a 512-bit (128 hex character) digest, offering higher collision resistance and faster throughput on 64-bit processors.
