Validate encryption implementations and cryptographic practices. Use
Why this skill is useful
Adds specific commands and workflows for validating encryption implementations and cryptographic practices that the AI wouldn't reliably generate on its own.
What it needs
Requires encryption-tool installed locally. About 2k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
Encryption Tool Validate encryption implementations, audit cryptographic algorithm choices, and verify key management practices across codebases and configuration files. Overview This skill empowers Claude to handle data encryption and decryption tasks seamlessly. It leverages the encryption-tool plugin to provide a secure way to protect sensitive information, ensuring confidentiality and integrity. How It Works 1. Identify Encryption/Decryption Request: Claude analyzes the user's request to determine whether encryption or decryption is required. 2. Select Encryption Method: Claude prompts the user to specify the desired encryption algorithm (e.g., AES, RSA). If not specified, a default secure method is chosen. 3. Execute Encryption/Decryption: Claude utilizes the encryption-tool plugin to perform the encryption or decryption operation on the provided data or file. 4. Return Encrypted/Decrypted Data: Claude presents the encrypted or decrypted data to the user, or saves the result to a file as requested. When to Use This Skill This skill activates when you need to: Encrypt sensitive data before storage or transmission. Decrypt previously encrypted data for access or processing. Generate encrypted files for secure archiving. Examples Example 1: Encrypting a Text File User request: "Encrypt the file 'sensitivedata.txt' using AES." The skill will: 1. Activate the encryption-tool plugin. 2. Encrypt the contents of 'sensitivedata.txt' using AES encryption. 3. Save the encrypted data to a new file (e.g., 'sensitivedata.txt.enc'). Example 2: Decrypting an Encrypted File User request: "Decrypt the file 'confidential.txt.enc'." The skill will: 1. Activate the encryption-tool plugin. 2. Decrypt the contents of 'confidential.txt.enc' using the appropriate decryption key (assumed to be available or prompted for). 3. Save the decrypted data to a new file (e.g., 'confidential.txt'). …
