Frequently Asked Questions

What is Rail Fence Cipher Encoder / Decoder?
Encode and decode text with the rail fence cipher online for free. Zigzag transposition cipher with configurable number of rails and live preview.
What encoding standards are used?
This tool follows the official encoding specifications, including RFC standards where applicable. The implementation matches widely-used libraries so the output is compatible with other systems and programming languages.
Can I encode binary data?
The tool primarily handles text input, but many encoding formats such as Base64 are designed to represent binary data as text. You can paste Base64-encoded binary data for decoding or encode text into a binary-safe format.
Is the encoding reversible?
Yes, all encoding operations provided by this tool are fully reversible. You can encode text and then decode it back to get the exact original content without any data loss.
Is Rail Fence Cipher Encoder / Decoder free to use?
Yes, encoding and decoding are completely free with no usage limits. The tool runs in your browser and requires no registration.
Is my data safe when using Rail Fence Cipher Encoder / Decoder?
Yes, all encoding and decoding happens locally in your browser. No data leaves your device, so your input remains completely private.
