What is a Hash Generator?
A hash generator converts any input — text or files — into a fixed-length string using a cryptographic hash function. Even a single character change produces a completely different output, making hashes ideal for verifying data integrity.
This tool supports MD5, SHA-1, SHA-256, SHA-512, SHA3-256, and SHA3-512, with optional HMAC authentication. Everything runs client-side — your data never leaves your browser.
Supported Algorithms
MD5 · weak
128-bit. Fast but cryptographically broken. Use only for checksums.
SHA-1 · weak
160-bit. Deprecated for security. Still used in legacy systems.
SHA-256 · strong
256-bit. Industry standard. Used in TLS, Bitcoin, and code signing.
SHA-512 · strong
512-bit. Maximum security for high-sensitivity applications.
SHA3-256 · modern
Keccak sponge construction. Independent security from SHA-2.
SHA3-512 · modern
Highest security margin of all supported algorithms.
File Checksum Verification
Software distributors publish checksums alongside downloads so you can verify file integrity. Upload your file, generate the hash, paste the expected checksum, and verify — a green result means the file is intact.
Need Password Hashing?
MD5 and SHA are fast hashes — not designed for passwords. Use our Bcrypt Generator for secure password hashing with configurable cost factor and built-in salt.
