Dev Toolkit
Password, hash, JWT and URL utilities
Hash generator
MD5, SHA-1, SHA-256 and SHA-512 checksums.
Checksums, not passwords. These algorithms are built to be fast, which is exactly what an attacker wants. Store passwords with bcrypt instead. MD5 and SHA-1 are additionally broken against collisions — keep them for legacy checksums only.
MD5
Waiting for input
Broken for security. Legacy checksums only.
SHA-1
Waiting for input
Collisions are practical. Git object ids and legacy checksums only.
SHA-256
Waiting for input
The default checksum today — file integrity, signatures, HMAC.
SHA-512
Waiting for input
Wider digest, faster than SHA-256 on 64-bit hardware.
