About Hash Generator

Cryptographic hashes are one-way functions used for data integrity verification, password storage, and digital signatures. This tool generates SHA-1, SHA-256, SHA-512 (via Web Crypto API) and MD5 (via js-md5 library) hashes from text input or files. Compare file checksums to verify downloads. Everything runs in your browser — your data never leaves your device.

Frequently Asked Questions

Is my data sent to a server?

No. SHA hashes are computed using the Web Crypto API and MD5 using the js-md5 library — both run entirely in your browser.

Which hash algorithm should I use?

SHA-256 is the most widely used for checksums and data integrity. SHA-512 provides more security. MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security purposes like checksums.
