The Anticloud ecosystem includes 10 security and cryptography tools covering the full range of application security needs: from cryptographic primitives to threat modeling to identity verification.

Tool Categories​

Cryptographic Primitives​

The foundational tools provide core cryptographic operations that every developer needs at some point:

  • Hash Checker — Compute and verify cryptographic hashes across SHA-1, SHA-256, SHA-512, MD5, BLAKE2b, and BLAKE3. Supports file drag-and-drop, checksum file parsing (.sha256, .md5, .sfv), and batch processing with CSV export.

  • Encrypt Text — Symmetric and asymmetric encryption for text data. Supports AES-256-GCM, XChaCha20-Poly1305, and RSA-OAEP with key generation and passphrase-based key derivation.

  • Secure Random — Cryptographically secure random number generator backed by the OS entropy source. Generates random bytes, integers in range, UUIDs v4, and passphrases.

Identity & Authentication​

Tools for working with JWTs, TOTP tokens, and credential management:

  • JWT Inspector — Decode, inspect, and debug JSON Web Tokens. Validates signatures (HS256, RS256, ES256), checks expiration, and highlights security issues like alg=none attacks.

  • TOTP Generator — Generate and verify Time-based One-Time Passwords per RFC 6238. Supports multiple accounts, QR code import/export, and offline operation.

  • Credential Vault — Local-first encrypted credential manager. Stores secrets in a .aioss-signed vault file encrypted with XChaCha20-Poly1305.

Security Analysis​

Tools for understanding and improving application security posture:

  • Attack Surface Analyzer — Maps an application's attack surface by analyzing open ports, exposed endpoints, dependency vulnerabilities, and misconfigurations.

  • Threat Model — Structured threat modeling tool supporting STRIDE, PASTA, and LINDDUN methodologies. Generates threat matrices, mitigation recommendations, and risk scores.

  • Ledger Verifier — Verifies .aioss ledger chains by checking each entry's hash chain and Ed25519 signature. Reports chain integrity, timestamp ordering, and key consistency.

Using the Tools Together​

The security tools are designed to compose into security workflows. A typical secure development pipeline:

  1. Threat Model at design time to identify risks
  2. Attack Surface Analyzer on staging to verify deployment
  3. Hash Checker in CI to verify build artifact integrity
  4. JWT Inspector to debug authentication tokens
  5. Ledger Verifier to audit the .aioss security trail

Getting Started​

All tools are open source under the Anticloud repository:

git clone https://github.com/kleinnner/Anticloud.git
cd Anticloud/12-api-oss-tools
