What it does
Implementing Rsa Key Pair Management is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Generates, stores, rotates, and manages RSA key pairs following NIST SP 800-57 guidelines, covering serialization formats (PEM, DER, PKCS8), passphrase protection, and key strength validation. Use when creating or rotating RSA keys for signatures, key exchange, or encryption, or when auditing existing keys for proper storage and NIST-compliant strength.
Its SKILL.md is about 920 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).
It sits in Security, covering Cryptography. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
When your agent uses it
- Rotating RSA keys for signatures
- Auditing existing keys for proper storage and NIST-compliant strength
Example prompts
- “/implementing-rsa-key-pair-management”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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.
Context cost
Implementing Rsa Key Pair Management loads about 920 tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 346 words of instructions outside code blocks.
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.

Implementing RSA Key Pair Management
Overview
RSA (Rivest-Shamir-Adleman) is the most widely deployed asymmetric cryptographic algorithm, used for digital signatures, key exchange, and encryption. This skill covers generating, storing, rotating, and managing RSA key pairs following NIST SP 800-57 key management guidelines, including key serialization formats (PEM, DER, PKCS#8), passphrase protection, and key strength validation.
When to Use
- When deploying or configuring implementing rsa key pair management capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Familiarity with cryptography concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
Objectives
- Generate RSA key pairs with appropriate key sizes (2048, 3072, 4096 bits)
- Serialize keys in PEM and DER formats with PKCS#8
- Protect private keys with strong passphrase encryption
- Implement key rotation with versioning
- Extract public key components and fingerprints
- Validate key strength and detect weak keys
- Sign and verify data using RSA-PSS
Key Concepts
RSA Key Sizes and Security Strength
| Key Size (bits) | Security Strength (bits) | Recommended Until |
|---|---|---|
| 2048 | 112 | 2030 |
| 3072 | 128 | Beyond 2030 |
| 4096 | ~140 | Beyond 2030 |
RSA Padding Schemes
| Scheme | Use Case | Standard |
|---|---|---|
| OAEP | Encryption | PKCS#1 v2.2 (RFC 8017) |
| PSS | Signatures | PKCS#1 v2.2 (RFC 8017) |
| PKCS#1 v1.5 | Legacy only | Deprecated for new systems |
Key Storage Formats
- PEM: Base64-encoded with headers, human-readable
- DER: Binary ASN.1 encoding, compact
- PKCS#8: Standard for private key encapsulation
- PKCS#12/PFX: Bundled key + certificate, password-protected
Security Considerations
- Minimum 3072-bit keys for new deployments (NIST recommendation)
- Always protect private keys with AES-256-CBC passphrase encryption
- Use RSA-PSS for signatures (not PKCS#1 v1.5)
- Use RSA-OAEP for encryption (not PKCS#1 v1.5)
- Store private keys with restrictive file permissions (0600)
- Implement key rotation at least annually
Validation Criteria
- Key generation produces valid RSA key pair
- Public key can be extracted from private key
- Private key is protected with passphrase
- RSA-PSS signature verification succeeds
- Tampered signature verification fails
- Key fingerprint is computed correctly
- Key rotation maintains old key access for verification
