Hash Generator

Generate cryptographic hashes using MD5, SHA-1, SHA-256, and SHA-512 algorithms

Security Notice

MD5 and SHA-1 are deprecated for security purposes due to collision vulnerabilities. Use SHA-256 or SHA-512 for cryptographic security. MD5/SHA-1 are suitable only for checksums and non-security applications.

Hash Algorithm Information

MD5 (Message Digest 5)

128-bit hash value. Fast but cryptographically broken. Suitable only for checksums and non-security purposes like file integrity verification. NOT for passwords or security.

SHA-1 (Secure Hash Algorithm 1)

160-bit hash value. Deprecated since 2017 due to collision attacks. Use SHA-256 or SHA-512 instead for any security-critical applications.

SHA-256 (Secure Hash Algorithm 256)

256-bit hash value. Part of SHA-2 family. Currently secure and widely used for digital signatures, SSL certificates, and blockchain. Recommended for most security applications.

SHA-512 (Secure Hash Algorithm 512)

512-bit hash value. Part of SHA-2 family. Provides higher security margin than SHA-256. Recommended for high-security applications and password hashing (with salt).

Common Use Cases:

  • • File Integrity: Verify file downloads haven't been corrupted (use SHA-256)
  • • Password Storage: Hash passwords before database storage (use SHA-256/512 with salt and iterations)
  • • Digital Signatures: Create unique fingerprints for documents (use SHA-256/512)
  • • Blockchain: Create block hashes and proof-of-work (uses SHA-256)
  • • Checksums: Quick file comparison and deduplication (MD5/SHA-1 acceptable)
  • • Data Integrity: Verify data hasn't changed during transmission
