Generatore di Hash Crittografico

Genera istantaneamente impronte hash MD5, SHA-1, SHA-256 e SHA-512 da qualsiasi stringa di testo.

MD5 (128-bit)
SHA-1 (160-bit)
SHA-256 (256-bit)
SHA-512 (512-bit)

Cos'è un Hash Crittografico?

È un algoritmo matematico unidirezionale che associa dati di qualsiasi lunghezza a una stringa univoca di lunghezza fissa.

Confronto tra MD5, SHA-1 e SHA-256

  • MD5 (Message Digest 5): Produces a 128-bit hash. While deprecated for security due to collision vulnerabilities, it remains popular for verifying file download integrity and quick checksums.
  • SHA-1 (Secure Hash Algorithm 1): Produces a 160-bit hash. Previously standard in SSL certificates, now replaced by the SHA-2 family.
  • SHA-256: Part of the SHA-2 family, produces a 256-bit hash. Highly secure and foundational to modern SSL/TLS encryption, digital certificates, and cryptocurrencies like Bitcoin.
  • SHA-512: An ultra-secure 512-bit hash function offering maximum security against brute force and quantum computing threats.
