MD5 Hash Generator & Base Converter

Generate secure hashes and convert numbers between different base systems

Understanding Hash Functions & Number Systems

🔐 Cryptographic Hash Functions

MD5 (Message Digest 5)

128-bit hash. Fast but cryptographically broken. Use only for checksums, never for security.

⚠️ Vulnerable to collision attacks - deprecated for security use

SHA-1 (Secure Hash Algorithm 1)

160-bit hash. Being phased out due to vulnerabilities. Legacy systems only.

⚠️ Deprecated by major browsers and security standards

SHA-256 (Secure Hash Algorithm 256)

256-bit hash. Currently secure and recommended for most applications.

✅ Recommended for password hashing, digital signatures, certificates

SHA-512 (Secure Hash Algorithm 512)

512-bit hash. Higher security margin, better for high-security applications.

✅ Recommended for enterprise and government applications

🛡️ Security Best Practices:

  • • Never use MD5 or SHA-1 for password storage
  • • Always use salt when hashing passwords
  • • Consider purpose-built functions like bcrypt, scrypt, or Argon2
  • • Use HMAC for message authentication

🔢 Number System Conversions

Binary (Base 2)

Uses only 0 and 1. Foundation of all computer systems and digital logic.

Example: 1010₂ = 10₁₀

Octal (Base 8)

Uses digits 0-7. Common in Unix file permissions and legacy systems.

Example: 755₈ = 493₁₀ (rwxr-xr-x permissions)

Decimal (Base 10)

Standard human number system using digits 0-9.

Default representation in most programming languages

Hexadecimal (Base 16)

Uses 0-9 and A-F. Essential for colors, memory addresses, and byte representation.

Example: #FF0000 = red color, 0x1A3F = 6719₁₀

Common Use Cases:

Binary: Bit manipulation, flags, embedded systems
Octal: File permissions, legacy system configurations
Hex: Colors, memory dumps, cryptographic keys
