Developer Utility Tools

A VS Code extension providing essential tools for developers, including data formatting, certificate management, and various encoding/decoding utilities.

Features

🔐 AES Encrypt / Decrypt (Generic)

Encrypt and decrypt content using configurable AES settings.

• Enabled by Default: Uses command devx.aesEncryptDecryptGeneric and appears in the DevX sidebar by default
• Input Sources: Text, File, and URL (http/https) input supported
• Details Panel UX: Details is collapsed by default; use the dropdown button on the right to expand/collapse options
• Cipher Options:
  • Key Sizes: 128, 192, 256
  • Modes: CBC, CFB, CTR, OFB, ECB
  • Paddings: Pkcs7, Iso97971, AnsiX923, Iso10126, ZeroPadding, NoPadding
• Key Types:
  • PBKDF2
  • EvpKDF
  • Custom (with explicit Key/IV)
• Derivation Controls: Hash selection, salt type (random / nosalt / custom), custom iteration toggle
• OpenSSL Salt Prefix: Uses Salted__ prefix when derived-key flow uses salt
• Basic Encodings: UTF-8, Hex, Base64 for input/output and custom key material fields
• Decryption Safety: Auto-detects Base64/Hex ciphertext when decrypting text to reduce encoding mismatch issues
• Output Actions: Copy button in output panel

🔤 Base64 Encode/Decode

Encode and decode Base64 strings with support for both text and file inputs.

• Text Mode: Encode/decode plain text strings
• File Mode: Upload or drag-and-drop files for Base64 encoding
• Copy Support: Easy clipboard integration

🔑 JWT Debugger

Decode and validate JWT (JSON Web Token) tokens.

• Token Decoding: View header, payload, and signature components
• Expiration Check: Validates token expiration timestamps
• Pretty Print: Formatted JSON output for easy reading

🆔 UUID Generator

Generate UUIDs in multiple formats for various use cases.

• UUID v1: Timestamp-based UUIDs
• UUID v4: Random UUIDs
• UUID v7: Timestamp-ordered UUIDs (ideal for database primary keys)
• Null UUID: Generate empty UUID (00000000-0000-0000-0000-000000000000)
• Bulk Generation: Generate up to 1000 UUIDs at once

🔤 Escape/Unescape Tool

Format text by escaping or unescaping special characters.

• Supported Characters:
  • \n - Newline
  • \r - Carriage return
  • \t - Tab
  • \f - Form feed
  • \b - Backspace
  • \" - Double quote
  • \' - Single quote
  • \\ - Backslash

📄 Data Formatter

Format and beautify XML, JSON, and SQL code.

• XML Formatting: Pretty-print or minify XML documents
• JSON Formatting: Format JSON with customizable indentation (2-8 spaces)
• SQL Formatting: Auto-format SQL queries with proper indentation
• Minify Support: Compress XML and JSON (remove whitespace)

🔐 Certificate Tools

Comprehensive certificate management utilities.

• Validate Certificates: Check certificate validity, expiration, and format
• Decode Certificates: Extract detailed certificate information (subject, issuer, fingerprint, etc.)
• JKS Extraction: Instructions for extracting certificates from Java KeyStore
• PKCS12 Conversion: Generate OpenSSL commands to convert certificates to PKCS12 format

🎯 Activity Bar Integration

Access all Utility tools from the dedicated activity bar icon for quick navigation.

Requirements

• VS Code version 1.105.0 or higher
• Node.js (for development)

Extension Settings

This extension does not currently add any VS Code settings. Configuration is done through the UI panels.
