Encryption vs. Hashing: What's the Difference?
In the world of data security, encryption and hashing are two fundamental concepts that are often confused.
- Encryption is a two-way function. You can scramble data (encrypt) and then unscramble it (decrypt) using a key. It's like locking a document in a safe; you can take it out if you have the key.
- Hashing is a one-way function. It turns data into a unique string of characters (a hash). You cannot reverse the process to get the original data back. It's like grinding coffee beans; you can't turn the grounds back into beans.
Protecting Your Messages
If you need to send a private message over an insecure channel, encryption is your best friend. Our Encrypt / Decrypt Text tool supports robust algorithms like AES and TripleDES.
- Enter your secret message.
- Choose a strong password (key).
- Encrypt it.
- Send the encrypted text to the recipient.
- They use the same tool and password to decrypt it.
Verifying File Integrity
How do you know a file hasn't been tampered with during download? This is where hashing comes in.
By generating a hash of a file using our File Hash Generator, you create a digital fingerprint. If even a single bit of the file changes, the hash will be completely different.
- MD5: Fast, but less secure. Good for basic integrity checks.
- SHA-256: Highly secure. The industry standard for verifying file authenticity.
Securing Files
For sensitive documents, use the File Encrypt / Decrypt tool. It uses client-side AES encryption to lock your files with a password before you upload them to cloud storage or email them. Since the encryption happens in your browser, the unencrypted file never leaves your device.
