Hash Tools
Free hash generator and checksum tools online. Create MD5, SHA-256, SHA-512, CRC32 hashes from text or files. Verify file integrity, compare hashes, and identify hash types—all in your browser.
Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-512, and CRC32 hashes from text or files, all in one place.
MD5 Hash Online
Create an MD5 checksum from text or a file with this fast MD5 calculator.
SHA-256 Hash
Generate secure 256-bit SHA-256 hashes from text or files.
SHA-512 Hash
Generate 512-bit SHA-512 hashes when you need maximum strength.
SHA-1 Hash
Create 160-bit SHA-1 hashes, still handy for Git commits and file verification.
CRC32 Checksum
Calculate a CRC32 checksum for quick file-integrity checks.
Hash Identifier
Not sure what a hash is? Detect whether it looks like MD5, SHA-256, bcrypt, or another type.
Compare Hashes
Compare two hashes with case-insensitive matching and a clear match indicator.
File Checksum
Verify a downloaded file hash against the expected value to confirm integrity.
Hash Lookup
Reverse-lookup an MD5 or SHA-1 hash to see if it matches a known value.
HMAC Generator
Generate keyed HMAC-SHA256 and HMAC-SHA512 authentication codes.
Hash Converter
Convert a hash between hex and Base64, change its case, or add byte separators.
