Hash Encoder

Generate multiple types of hashes from text input. Compare different algorithms and their security levels.

Security Recommendations:
  • • Use SHA-256 or SHA-512 for security-critical applications
  • • Avoid MD5 and SHA-1 for new projects
  • • For password hashing, use specialized algorithms like bcrypt, scrypt, or Argon2
  • • All processing happens locally in your browser for privacy

About Hash Encoding

Cryptographic hash functions are mathematical algorithms that convert input data into fixed-size strings of characters. They are essential for data integrity, digital signatures, and various security applications.

Algorithm Comparison:

  • MD5: 128-bit, fast but cryptographically broken
  • SHA-1: 160-bit, deprecated due to collision vulnerabilities
  • SHA-224: 224-bit, truncated SHA-256
  • SHA-256: 256-bit, current standard for security
  • SHA-384: 384-bit, truncated SHA-512
  • SHA-512: 512-bit, highest security level

Common Applications:

  • File integrity verification and checksums
  • Digital certificates and signatures
  • Blockchain and cryptocurrency
  • Password verification systems
  • Data deduplication
  • Cache keys and unique identifiers

Hash Properties:

  • Deterministic: Same input always produces same output
  • Fixed Size: Output length is always the same
  • One-way: Cannot reverse hash to get original input
  • Avalanche Effect: Small input changes cause large output changes
  • Collision Resistant: Difficult to find two inputs with same hash
