Password & Hash

Password and Hash Tools

Password and hash tools provide common hash calculation, message authentication, and password hashing functions for software development, data integrity verification, security testing, and technical debugging.

Which Hash Algorithms Are Supported?

Common hash algorithms include MD5, SHA-1, SHA-256, SHA-384, SHA-512, and SHA-3. Hash functions convert data of arbitrary length into a fixed-length digest and are commonly used for file verification, data integrity checks, and development testing.

Which Password Hashing Algorithms Are Supported?

Password-related algorithms include bcrypt, PBKDF2, scrypt, and Argon2. Unlike general-purpose hashes such as MD5 and SHA-256, password hashing algorithms are designed to make password guessing more expensive and are better suited for password storage.

What Is the Difference Between Hashing and Password Hashing?

General-purpose hashing is commonly used for data identification and integrity verification, while password hashing uses techniques such as salts and configurable computational costs to make brute-force attacks more difficult. Modern applications should select a password hashing algorithm appropriate for their security requirements.

Common Use Cases

• Calculate MD5, SHA-256, and other hashes for text or data
• Verify downloaded file integrity
• Debug hash-related application logic
• Test HMAC authentication and message integrity
• Evaluate password hashing configurations

Is It Safe to Use Online?

Online hash tools are useful for testing and development data. Do not submit real passwords, API keys, private keys, authentication tokens, or other sensitive information to online services.
