Free Hash Generator (MD5 / SHA / SHA3)

Generate cryptographic hashes from text or files using MD5, SHA-1, SHA-256, SHA-384, SHA-512 and SHA3-256/512. All hashing happens locally in your browser — nothing is uploaded.

Password Generator

Create strong random passwords before hashing or storing them.

Open

Password Strength Checker

Test how strong a password is before hashing.

PEM / DER Converter

Convert certificates and keys before signing or hashing.

Input Type

Text File

Choose whether to hash plain text or the contents of a file.

Text Input

Text is interpreted as UTF-8 before hashing. For passwords or secrets, enable masking below.

File Input

Drop a file here or click to browse

Any file type is supported. Only size is limited by your browser’s memory.

No file selected.

Options Auto update hashes while typing (text mode) Uppercase output (A–F) instead of lowercase Mask sensitive fields (blur text on screen)

HMAC (Optional) Use HMAC instead of plain hash (requires secret key)

HMAC is applied for MD5, SHA-1, SHA-256, SHA-384 and SHA-512. SHA3 hashes will still be computed as normal hashes.

Hash Summary

Waiting for input…

Source: Text

Data Size: 0 bytes

Algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512

Mode: Hash

MD5 Legacy / Insecure

128-bit • Fast but not secure for passwords or signatures.

SHA-1 Legacy / Broken

160-bit • Collisions known — avoid for new systems.

SHA-256 Recommended

256-bit • Common choice for file integrity and APIs.

SHA-384

384-bit • Stronger variant in the SHA-2 family.

SHA-512

512-bit • Strong SHA-2, better for 64-bit systems.

SHA3-256 SHA-3

256-bit • Keccak-based SHA-3 family (FIPS 202).

SHA3-512 SHA-3

512-bit • Very strong Keccak-based hash.
