Shamir's Secret Sharing (M-of-N Key Splitter)
Cryptographically split master passwords, recovery seed phrases, and confidential keys into N threshold shares over Galois Field GF(256) where any K shares reconstruct the secret.
Zero-Knowledge AES-256 File Encryption Vault
Military-grade client-side file and document encryption using AES-256-GCM and PBKDF2 with 100,000 SHA-256 iterations. Encrypt photos, PDFs, and text into private .vedvault containers.
Regex ReDoS Vulnerability & Catastrophic Backtracking Scanner
Scan and audit regular expressions for catastrophic polynomial and exponential backtracking risks (ReDoS). Evaluates nested quantifiers, overlapping groups, evil string payloads, and safe DFA rewrites in browser RAM.
Steganography Pixel Vault (Hide Encrypted Secrets in Photos)
Hide and extract encrypted confidential text, passwords, and cryptocurrency recovery seeds inside lossless image pixels using Least Significant Bit (LSB) encoding and AES-256-GCM encryption in browser RAM.
Bulk CSV to Barcode & QR Sticker Sheet Generator
Batch-convert CSV or Excel product catalogs (Product Name, SKU/Code, MRP Price) into printable A4 24-up or 40-up retail barcode and QR code sticker sheets with automatic GS1 EAN-13 checksums in local RAM.
Env to Kubernetes Secret Generator
Convert .env files or key-value environment variables into Kubernetes Secret YAML or JSON 100% in browser RAM. Supports Base64 encoding, stringData, custom namespace, and immutable secret flags.
HAR & Server Log PII Redactor
Scrub sensitive authentication tokens, session cookies, Bearer credentials, API keys, passwords, and IP addresses from HTTP Archive (.har) and server log files locally before sharing with teams.
OpenAPI & Swagger Security Auditor
Audit OpenAPI 3.0/3.1 and Swagger 2.0 specifications against 24 security and hygiene checks in browser memory. Detects missing auth scopes, unencrypted endpoints, missing rate limits, and unconstrained schemas.
Why In-Browser Execution Is the Future of Developer Productivity
In an enterprise environment governed by SOC 2 Type II, HIPAA, and GDPR regulations, pasting authorization tokens or proprietary system prompts into remote third-party cloud servers is a critical vulnerability.
Pure RAM Execution
All decoding, hashing, regex matching, and AST JSON validation execute strictly within the browser thread’s memory allocation. When you close the browser tab, the data evaporates completely.
Pre-LLM Sanitization
Modern AI models (ChatGPT, Claude, Gemini) store conversation prompts for inference and training. Scrubbing API keys, AWS credentials, and PII before prompting eliminates data spill risks.
Native Web Crypto API
Cryptographic calculations leverage hardware-accelerated C++ browser primitives (crypto.subtle), delivering gigabyte-scale throughput with zero network round-trip overhead.
Frequently Asked Questions
Is it safe to paste production JWTs and API keys here?
Yes, 100%. VedKit does not have backend processing servers for developer tools. You can inspect your browser's Network tab (F12) while using these tools and verify that zero HTTP POST/GET requests are dispatched when pasting tokens or generating hashes.
How does the AI Prompt Secret Scrubber work?
The scrubber uses high-entropy regex heuristic parsers calibrated for official key formats (OpenAI, AWS, GitHub, Stripe, Slack, DB strings, emails, phone numbers). It provides both token substitution (e.g. [REDACTED_OPENAI_API_KEY]) and asterisk masking before you send code snippets to AI assistants.
What hash algorithms are supported for large file verification?
The Cryptographic Hash Studio supports SHA-256, SHA-512, SHA-384, SHA-1, and MD5. Files up to 2 GB can be dropped directly from your local filesystem for instant checksum matching against official release hashes.
