Hash Generator
Compute cryptographic hashes using MD5, SHA-1, SHA-256, or SHA-512. Output as hexadecimal or Base64.
About Hash Functions
- MD5
- 128-bit hash. Fast but not suitable for security-sensitive use — collisions are feasible.
- SHA-1
- 160-bit hash. Deprecated for cryptographic use; attacks are known but uncommon in practice.
- SHA-256
- 256-bit hash from the SHA-2 family. The go-to choice for checksum verification and digital signatures.
- SHA-512
- 512-bit hash, higher security margin. Preferred where length-extension attacks are a concern.
Never hash passwords with these alone. Use a purpose-built algorithm like bcrypt, Argon2, or PBKDF2.
