How to use the Text Encryption Tool?
Choose a method like Base64 or ROT13, paste your text into the input field, and click "Process". The tool encrypts (or decrypts) your text instantly in your browser. Since this tool is purely client-side, your data never leaves your device.
Supported Algorithms
- Base64: A standard encoding scheme used to securely transmit data across protocols like email or web forms.
- ROT13: A simple substitution cipher that replaces a letter with the 13th letter after it. Applying it twice yields the original text.
- Hexadecimal: Converts text into its numerical Hex representations.
Example
Encoding "hello" in Base64 produces aGVsbG8=; decoding it returns "hello".
Common Use Cases
- Encoding binary or text data for safe transmission in APIs or emails.
- Quickly obfuscating text for puzzles or casual privacy (not real security).
FAQs
Is Base64 or ROT13 real encryption?
No — both are reversible encoding/obfuscation schemes, not cryptographic encryption; anyone can decode them without a key.
