Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-3, SHA-384, SHA-512, BLAKE2b, and BLAKE2s hashes from text. Useful for checksums and data integrity verification.
How to Use
Enter Your Text
Type or paste the text you want to hash in the input field.
Generate Hashes
Click "Generate Hashes" to compute MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously.
Copy the Hash
Click the "Copy" button next to any hash to copy it to your clipboard.
FAQ
What is a hash function?
A hash function takes input data and produces a fixed-size string of characters (the hash). The same input always produces the same hash, but it's computationally infeasible to reverse the process or find two inputs with the same hash.
Which hash algorithm should I use?
SHA-256 or SHA-3 are recommended for most security use cases. Here's a quick guide:
- MD5 (128-bit) - Fast but cryptographically broken. Use only for checksums, not security.
- SHA-1 (160-bit) - Deprecated for security. Still used in legacy systems.
- SHA-256 (256-bit) - Industry standard. Excellent balance of security and performance.
- SHA-3 (256-bit) - Newest standard, different design from SHA-2 family.
- SHA-384/512 (384/512-bit) - Maximum security, longer output.
- BLAKE2b (512-bit) - Faster than SHA-3, highly secure, great for large files.
- BLAKE2s (256-bit) - Optimized for 32-bit platforms, faster on smaller devices.
What algorithms are supported?
This tool supports 8 hash algorithms:
- MD5 - 32 character hex output
- SHA-1 - 40 character hex output
- SHA-256 - 64 character hex output
- SHA-3 (256) - 64 character hex output
- SHA-384 - 96 character hex output
- SHA-512 - 128 character hex output
- BLAKE2b - 128 character hex output (64 bytes)
- BLAKE2s - 64 character hex output (32 bytes)
Is hashing the same as encryption?
No. Hashing is one-way - you cannot recover the original data from a hash. Encryption is two-way - you can decrypt encrypted data with the right key.
Is my data secure?
Yes. All hashing happens in your browser. Your data never leaves your device.
