Sicherer Passwort-Hash für PHP, Laravel, Node.js etc. Bcrypt ist langsam by design — jeder Hash dauert je nach Cost Factor etwas länger.
Is MD5 still secure?
MD5 is no longer considered cryptographically secure and should not be used for passwords or security purposes. For checksums it is still acceptable.
Which hash algorithm should I use?
For most applications we recommend SHA-256. For passwords you should use specialised algorithms such as bcrypt or Argon2.
Can a hash be decrypted?
No, hashes are one-way functions. You cannot "decrypt" a hash – you can only crack it via brute-force or rainbow tables.
Is my data stored?
No, all calculations happen exclusively in your browser. Your data never leaves your computer.
What is a hash?
A hash is a one-way function that converts data of arbitrary size into a fixed-length value.
Hash algorithms
- MD5: 128-bit (deprecated for security)
- SHA-1: 160-bit (no longer recommended)
- SHA-256: 256-bit (recommended)
- SHA-512: 512-bit (very secure)
Use cases
- Password storage
- File integrity verification
- Digital signatures
- Checksums
- Cache keys
Security
All calculations are performed locally in your browser. Your data is never sent to a server.
