Frequently Asked Questions

A cipher is a method used to encrypt or decrypt information. In encryption, a cipher transforms plaintext (readable data) into ciphertext (encoded data) using a specific algorithm and key. This makes the information unreadable to anyone who does not possess the correct key. Decryption is the reverse process, where the ciphertext is converted back into its original plaintext form.
Simply input your text, choose a shift key if needed, and click "Encrypt" or "Decrypt" to see the result. The tool will handle the rest for you!
Yes, your data is only processed locally in your browser and is not sent to any server.
Cryptography is the practice and study of techniques for securing communication and data in the presence of adversaries. It involves converting plaintext into ciphertext to protect information from unauthorized access.
A key is a piece of information used in conjunction with a cipher to encrypt or decrypt data. The security of the encrypted data depends on the secrecy and strength of the key.
