What's the difference between Base64 and Caesar Cipher encryption?
Base64 is an encoding scheme that converts binary data to ASCII text, not true encryption but useful for data transmission. Caesar Cipher is a substitution cipher that shifts letters by a fixed number, providing basic encryption but easily breakable for sensitive data.
Is my data secure when using this tool?
Yes, all encryption and decryption happens locally in your browser. Your data is never transmitted to our servers or stored anywhere. For maximum security, we recommend using this tool in a private browsing session and clearing your browser cache after use.
When should I use Base64 vs Caesar Cipher?
Use Base64 for encoding data for transmission (like in URLs or email) where you need to preserve binary data as text. Use Caesar Cipher for simple obfuscation or educational purposes, but not for sensitive information as it's easily crackable.
Can I decrypt Caesar Cipher without knowing the shift key?
Caesar Cipher only has 25 possible keys, so it can be easily broken by trying all possible shifts (brute force attack). This makes it unsuitable for securing sensitive information but useful for learning about basic cryptography concepts.
What types of characters can be encrypted with these methods?
Base64 can encode any binary data including special characters, emojis, and file contents. Caesar Cipher only encrypts alphabetical characters (A-Z, a-z) and leaves numbers, spaces, and special characters unchanged.
