What is Hash Generator?
Hash Generator creates cryptographic hash values from any text input. It supports multiple algorithms including MD5, SHA-1, SHA-256, and SHA-512. Hashes are fixed-length outputs used for data integrity verification, password storage, and digital signatures.
Common Use Cases
File Integrity
Generate checksums to verify files haven't been modified.
Password Storage
Learn how password hashing works (use bcrypt/argon2 for production).
Data Deduplication
Create content hashes to identify duplicate files or records.
API Security
Generate HMAC signatures for API request authentication.
How to Use This Tool
- Enter the text you want to hash
- Select one or more hash algorithms
- View the generated hash values
- Copy the hash for your use case
Frequently Asked Questions
What is the difference between MD5 and SHA-256?
SHA-256 is more secure and collision-resistant than MD5. MD5 is deprecated for security purposes but still used for checksums.
Can you reverse a hash?
No. Cryptographic hashes are one-way functions. You cannot retrieve the original input from a hash.
Which hash should I use?
For security purposes, use SHA-256 or SHA-512. For simple checksums, MD5 or SHA-1 may suffice.
