dev-crypto-toolkit
Delivers utilities for JWT token decoding, data hashing, UUID generation, password processing, Base64 encoding/decoding, and timestamp manipulation. Backend developers and security engineers apply these for token validation, secure credential storage, unique record identification, and data transmission in web services.
Overview
The dev-crypto-toolkit MCP server exposes cryptographic primitives via API, including JWT decoding, hashing, UUID generation, password handling, Base64 transformations, and timestamp operations. These functions enable programmatic security tasks without external libraries.
Key Capabilities
- JWT decode: Extracts claims and verifies structure from JWT tokens.
- hash: Computes hashes (e.g., SHA-256) for data integrity or obfuscation.
- UUID: Generates version 4 UUIDs for unique identifiers.
- password: Hashes passwords with salts and verifies matches.
- base64: Encodes/decodes strings or binaries in Base64 format.
- timestamps: Creates Unix timestamps or formats for expiration checks.
Use Cases
- Validate incoming JWT decode in an API gateway to authorize requests and retrieve user claims.
- Store new user accounts by applying password hashing before database insertion.
- Assign UUID to log entries or session tokens in distributed systems.
- Prepare payloads with base64 encoding for secure HTTP transmission, using timestamps for expiry.
Who This Is For
Backend developers implementing authentication flows, security engineers handling token and credential ops, full-stack teams needing lightweight crypto functions for Node.js or Python apps.
