How to Use

Basic Usage

  1. Enter the text you want to hash in the input field
  2. Select your desired hash algorithm (default: SHA-256)
  3. Adjust hash formatting in advanced settings if needed
  4. Copy the generated hash values or compare with other hashes

Hash Algorithm Descriptions

MD5 (128-bit): Fast but cryptographically broken. Recommended only for checksums and duplicate file detection
SHA-1 (160-bit): More secure than MD5 but currently not recommended. Used in legacy systems like Git
SHA-256 (256-bit): Currently recommended strong hash. Used in cryptocurrencies, digital signatures, and security authentication
SHA-512 (512-bit): Strongest hash algorithm. Used in high-security systems and long-term preservation signatures

Security Levels

Deprecated: Algorithms that should no longer be used (vulnerable to collision attacks)
Weak: Vulnerable to specific attacks but still used for certain purposes
Strong: Currently recommended security level algorithms
Very Strong: Algorithms providing the highest level of security

⚠️

Important Security Notice

Do not use MD5 and SHA-1 for important data due to security vulnerabilities.

For actual password storage, use dedicated hashing algorithms like bcrypt, scrypt, or Argon2.

This tool should be used for educational and development purposes only.
