Tips & Guide
Hash Functions vs Encryption
Hashing is a one-way operation — you cannot reverse a hash to get the original text. Encryption is two-way (encrypt/decrypt). Use hashing for password storage and data integrity verification. Use encryption when you need to retrieve the original data.
Which Hash Algorithm to Choose
SHA-256 is the standard choice for most applications (file checksums, data integrity, blockchain). SHA-1 is deprecated for security use but still appears in legacy systems. SHA-512 provides extra security margin for sensitive applications.
Frequently Asked Questions
Is my data sent to a server?
No. All hashing is performed locally in your browser using the Web Crypto API. Your text never leaves your device.
