Compute MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files instantly. Web Crypto API powered.
A hash is a fixed-length string generated from any input using a mathematical algorithm. The same input always produces the same hash, but the process cannot be reversed.
For security, prefer SHA-256 or SHA-512. MD5 and SHA-1 are cryptographically weak — use them only for checksums, not security.
Yes — all hashing runs entirely in your browser using the Web Crypto API. No data is ever sent to any server.
Yes! Switch to File mode, drop your file in, and all hashes are computed locally in your browser.
Switch between Text and File mode. For text: type or paste content and hashes generate instantly. For files: upload any file and all four hash types compute in your browser.
MD5 (128-bit) is fast but not secure for passwords. SHA-256 is the security standard for digital signatures and certificates. SHA-512 provides maximum security. Use SHA-256 or SHA-512 for security purposes.
Generate cryptographic hashes for text or files. Supports MD5, SHA-1, SHA-256, and SHA-512 algorithms. Use for verifying file integrity, password hashing, API authentication, and data validation. All hashing runs locally in your browser using the Web Crypto API.
File hashing is privacy-sensitive — hashing locally means your files and sensitive text data are never uploaded.
Select Text (paste text) or File (upload a file to hash).
Paste text or drag a file.
Select MD5, SHA-1, SHA-256, or SHA-512.
The hash appears instantly — click to copy.
MD5 and SHA-1 are older and not recommended for security — use for checksums only. SHA-256 and SHA-512 are modern and cryptographically secure.
Yes — upload any file and generate its SHA-256 checksum to verify integrity.
No — hash functions are one-way. You cannot recover the original text from a hash.
MD5 is still used for non-security checksums (file integrity) but not for password hashing or security.
Yes — generate the SHA-256 hash of the downloaded file and compare it to the official checksum.
