Generate Secure Cryptographic Hashes
A powerful tool for generating cryptographic hashes using multiple algorithms including MD5, SHA-1, SHA-256, and SHA-512. Perfect for password hashing, data integrity verification, and digital signatures.
The Hash Generator tool allows you to generate cryptographic hashes for any text input using industry-standard algorithms. Hash functions are one-way mathematical operations that convert input data into a fixed-size string of characters.
Tip: The tool generates all four hash algorithms simultaneously, giving you a complete view of your data's hash representation across different security levels.
The tool supports four widely-used cryptographic hash algorithms, each with different characteristics and use cases.
MD5 (Message Digest Algorithm 5) produces a 128-bit hash value. While fast and widely supported, it is considered cryptographically broken and should not be used for security-sensitive applications.
SHA-1 (Secure Hash Algorithm 1) produces a 160-bit hash value. It is also considered cryptographically weak for modern security requirements but may still be used in legacy systems.
SHA-256 is part of the SHA-2 family and produces a 256-bit hash. It offers excellent security and is widely recommended for most cryptographic applications.
SHA-512 is the strongest option in the SHA-2 family, producing a 512-bit hash. It provides the highest level of security but is computationally more expensive.
The Hash Generator provides a simple, intuitive interface for generating cryptographic hashes.
The tool accepts text input and automatically handles Unicode characters properly. A character counter and byte counter help you track your input.
Shows the total number of characters in your input, including spaces and special characters.
Displays the actual byte length of your input, which may differ from character count for Unicode characters.
Note: The byte count uses UTF-8 encoding. Multi-byte characters (like emojis or accented letters) will result in a higher byte count than character count.
Each generated hash can be copied to your clipboard with a single click.
The tool displays useful information about each hash algorithm, including the bit strength and a brief description of its security level.

Generate hashes for files to verify they haven't been corrupted or tampered with during download or transfer.
Hash passwords before storing them. Use SHA-256 or SHA-512 for better security in modern applications.
Hash documents and data before signing them digitally. The hash serves as a unique fingerprint of the content.
Use hashes to identify duplicate files or data blocks without comparing the full content each time.
When using cryptographic hashes for security purposes, consider the following guidelines.
Warning: MD5 and SHA-1 are cryptographically broken and should never be used for password storage or security-critical applications. Even SHA-256 and SHA-512 should be used with proper salting and key derivation functions (like bcrypt, scrypt, or Argon2) for password storage.
