What it does

Encrypting And Decrypting Data is an agent skill from jeremylongshore/tons-of-skills-marketplace. Validate encryption implementations and cryptographic practices. Use when reviewing data security measures. Trigger with 'check encryption', 'validate crypto', or 'review security keys'.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `scripts/README.md`). Compatibility notes: Designed for Claude Code

It sits in Security, covering Cryptography. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Reviewing data security measures
  • With check encryption
  • Validate crypto
  • Review security keys

Example prompts

  • “check encryption”
  • “validate crypto”
  • “review security keys”
  • “/encrypting-and-decrypting-data”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(security:*), Bash(scan:*), Bash(audit:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  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…
  3. Execute Encryption/Decryption: Claude utilizes the encryption-tool plugin to perform the encryption or decryption operation on the…
  4. Return Encrypted/Decrypted Data: Claude presents the encrypted or decrypted data to the user, or saves the result to a file as requested.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • Bash(security:*)
    • Bash(scan:*)
    • Bash(audit:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Encrypting And Decrypting Data loads about 1.1k tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 511 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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 'sensitive_data.txt' using AES."

The skill will:

  1. Activate the encryption-tool plugin.
  2. Encrypt the contents of 'sensitive_data.txt' using AES encryption.
  3. Save the encrypted data to a new file (e.g., 'sensitive_data.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').

Best Practices

  • Key Management: Always store encryption keys securely and avoid hardcoding them in scripts.
  • Algorithm Selection: Choose encryption algorithms based on the sensitivity of the data and the required security level. Consider industry best practices and compliance requirements.
  • Data Integrity: Implement mechanisms to verify the integrity of encrypted data to detect tampering or corruption.

Integration

This skill can be integrated with other Claude Code plugins, such as file management tools, to automate the encryption and decryption of files during data processing workflows. It can also be combined with security auditing tools to ensure compliance with security policies.

Prerequisites

  • Access to codebase and configuration files in ${CLAUDE_SKILL_DIR}/
  • Security scanning tools installed as needed
  • Understanding of security standards and best practices
  • Permissions for security analysis operations

Instructions

  1. Identify security scan scope and targets
  2. Configure scanning parameters and thresholds
  3. Execute security analysis systematically
  4. Analyze findings for vulnerabilities and compliance gaps
  5. Prioritize issues by severity and impact
  6. Generate detailed security report with remediation steps

Output

  • Security scan results with vulnerability details
  • Compliance status reports by standard
  • Prioritized list of security issues by severity
  • Remediation recommendations with code examples
  • Executive summary for stakeholders

Error Handling

If security scanning fails:

  • Verify tool installation and configuration
  • Check file and directory permissions
  • Validate scan target paths
  • Review tool-specific error messages
  • Ensure network access for dependency checks

Resources

  • Security standard documentation (OWASP, CWE, CVE)
  • Compliance framework guidelines (GDPR, HIPAA, PCI-DSS)
  • Security scanning tool documentation
  • Vulnerability remediation best practices
