How do I trigger the encryption?

You can trigger the skill by asking Claude to 'encrypt', 'decrypt', or 'cipher' a specific message.

Does this skill require any external dependencies?

This skill requires a bash environment to execute the shell scripts responsible for the text transformation.

Is the encryption process reversible?

Yes, applying the ROT13 operation twice returns the original text, making it easy to decode any message encrypted with this skill.

ROT13 is a simple substitution cipher that replaces a letter with the 13th letter after it in the alphabet. Because there are 26 letters, it is its own inverse.

Can I use this for high-level security?

No, ROT13 is intended for basic obfuscation and text transformation. It is not secure against modern cryptographic analysis or attacks.

Security & Testing

Encrypts and decrypts text messages using the classic ROT13 substitution cipher via bash scripts.

About

This skill provides Claude with the specialized capability to perform basic message obfuscation and recovery using the ROT13 (rotate by 13 places) cipher. It serves as a lightweight utility for text processing within the terminal environment, allowing users to quickly transform strings for simple privacy, puzzle-solving, or formatting purposes. By integrating a dedicated bash-based encryption script directly into the workflow, it streamlines the process of encoding and decoding messages without requiring external web-based tools or complex cryptographic libraries.
