Hash Algorithm Comparison
| Algorithm | Output Size | Security | Speed | Use Case |
|---|---|---|---|---|
| SHA-1 | 160 bits (40 hex) | Weak | Fast | Legacy systems, git commits |
| SHA-256 | 256 bits (64 hex) | Strong | Medium | SSL, blockchain, general use |
| SHA-384 | 384 bits (96 hex) | Strong | Medium | TLS, high-security apps |
| SHA-512 | 512 bits (128 hex) | Very Strong | Slower | Maximum security needs |
FAQ – Hash Generator
What is a hash function?
A hash function converts input of any size into a fixed-size string of characters. The same input always produces the same hash, but you can't reverse a hash back to the original input.
Is hashing the same as encryption?
No. Hashing is one-way — you can't reverse it. Encryption is two-way — you can decrypt with the right key. Hashing is for verification, encryption is for confidentiality.
Is SHA-1 still safe?
SHA-1 is considered cryptographically broken for collision resistance. Use SHA-256 or higher for security-critical applications. SHA-1 is still used in git and some legacy systems.
Why does the same text always produce the same hash?
Hash functions are deterministic — the same input always yields the same output. This is what makes them useful for verification and integrity checks.
Is my data safe?
Yes. Hashing uses the browser's Web Crypto API. Nothing is sent to any server. Your text never leaves your device.
What about MD5?
MD5 is not available in the Web Crypto API due to known vulnerabilities. Use SHA-256 or higher for any security purpose. MD5 should only be used for non-security checksums.
