AI Agent Integration

Register the local NodeCrypto MCP server in Claude Code, Claude Desktop, VS Code, or Cursor to build, verify, and save .ncw workflows from natural language.

Local MCP.ncw
Built-in Script Language

Syntax, static types, operators, 24 built-in byte/integer functions, diagnostic codes, and resource limits for the deterministic Script node.

Python SubsetVerified I/O
Padding Standards

Byte-level rules, reversibility comparison, and color-coded byte block examples for the 7 block cipher padding methods.

7 StandardsByte Grid
Block Cipher Modes of Operation

Architecture, IV/nonce rules, security considerations, and SVG block diagrams for all 9 cipher modes (ECB, CBC, GCM, CCM, CTR, CFB, OFB, XTS, KW).

9 ModesSVG Diagrams
Port Order and Renaming

How to drag-reorder ports with grip handles, rename fixed or dynamic ports inline, and how permanent port IDs preserve wiring integrity.

Canvas UX
Node Properties Window and Memos

Moving and resizing the floating properties window, read-only canvas behavior while open, and writing Markdown node memos.

1Supply & Convert Inputs

Start with Static Value, Random Value, or Hex to Bytes to prepare typed Bytes, String, Int, or Bool inputs.

2Wire Cryptographic Nodes

Connect keys, nonces, and payloads into Symmetric, Asymmetric, Post-Quantum, or Script nodes.

3Inspect & Verify

Attach Output Inspector or Value Comparator to verify NIST/RFC test vectors interactively or via the MCP CLI.
