The project MUST enable one or more compiler warning flags, a "safe" language mode, or use a separate "linter" tool to look for code quality errors or common simple mistakes, if there is at least one FLOSS tool that can implement this criterion in the selected language.

The project addresses warnings through automated quality checks. All warnings from go vet, staticcheck, errcheck, and gosec are resolved before code merge. CI/CD pipeline enforces zero-warning policy via 'make check' target. https://github.com/agilira/harpocrates/blob/main/.github/workflows/ci.yml

The project maintains maximal strictness with warnings through multiple FLOSS linting tools (go vet, staticcheck, errcheck, gosec) configured for maximum sensitivity. Zero-warning policy is enforced via CI/CD pipeline with 'make check' quality gates that must pass before code merge. https://github.com/agilira/harpocrates/blob/main/Makefile, https://github.com/agilira/harpocrates/blob/main/.github/workflows/ci.yml

The project demonstrates secure software design knowledge through comprehensive security documentation including threat modeling (STRIDE+PASTA), cryptographic design documentation, and security-focused implementation. See: https://github.com/agilira/harpocrates/blob/main/threat-model.md

The project demonstrates comprehensive knowledge of cryptographic software vulnerabilities through detailed threat modeling (STRIDE+PASTA analysis), security-focused design documentation, and implemented countermeasures. Common vulnerabilities addressed include timing attacks (constant-time operations), memory disclosure (secure cleanup), weak key derivation (Argon2id), authentication bypass (GCM AEAD), and concurrency issues (thread-safe design). Evidence: https://github.com/agilira/harpocrates/blob/main/threat-model.md

The project uses only publicly published, expert-reviewed cryptographic standards by default: AES-256-GCM (NIST FIPS 197/SP 800-38D), Argon2id (RFC 9106), HKDF-SHA256 (RFC 5869), and PBKDF2-SHA256 (RFC 2898). All algorithms are NIST-approved or IETF standardized. No proprietary or unreviewed cryptographic methods are used. Documentation: https://github.com/agilira/harpocrates/blob/main/docs/cryptographic-design.md

N/A - Harpocrates is a cryptographic library whose primary purpose IS to implement cryptography. This criterion applies only to projects whose primary purpose is NOT cryptographic implementation.

All cryptographic functionality is implementable using only FLOSS tools and libraries. The project uses Go (BSD license), Go standard crypto library (BSD), golang.org/x/crypto (BSD), and other FLOSS dependencies. No proprietary cryptographic libraries or tools are required. Complete dependency list available in go.mod with all FLOSS-licensed components. https://github.com/agilira/harpocrates/blob/main/go.mod

The project uses AES-256 exclusively (256-bit keys), which exceeds NIST minimum requirements through 2030+ per SP 800-57. The KeySize constant enforces exactly 32-byte (256-bit) keys with validation that rejects smaller keys. No configuration options exist to enable weaker key lengths - smaller keys are completely disabled by design. https://github.com/agilira/harpocrates/blob/main/encryption.go

The project uses only secure, modern cryptographic algorithms by default: AES-256-GCM (NIST approved), SHA-256 (FIPS 180-4), Argon2id (RFC 9106), and cryptographically secure random generation. No broken algorithms (MD4, MD5, DES, RC4, Dual_EC_DRBG) are used. All cipher modes are appropriate (GCM for authenticated encryption). No interoperable protocol exceptions required. https://github.com/agilira/harpocrates/blob/main/docs/cryptographic-design.md

The project avoids cryptographic algorithms and modes with known serious weaknesses. Uses AES-256-GCM (no CBC vulnerabilities), SHA-256 (no SHA-1 collision issues), Argon2id (state-of-the-art), and secure constructions throughout. No weak algorithms like SHA-1, CBC mode, MD5, or RC4 are used by default security mechanisms. https://github.com/agilira/harpocrates/blob/main/docs/cryptographic-design.md

N/A - Harpocrates is a cryptographic library that provides encryption/decryption and key derivation functions, but does not implement key agreement protocols. It operates with pre-shared keys or derived keys rather than negotiating session keys through key agreement protocols where perfect forward secrecy would apply.

Harpocrates is a cryptographic library that provides encryption/decryption primitives and does not store passwords for external user authentication. However, the library does provide secure key derivation functions (Argon2id with per-user salt) that applications using this library could employ for secure password storage if needed.

All cryptographic keys and nonces in Harpocrates are generated exclusively using Go's crypto/rand package, which provides cryptographically secure random number generation backed by the operating system's secure random number generator. The library does not use any cryptographically insecure generators like math/rand. Evidence can be found in:

keyutils.go GenerateKey() and GenerateNonce() functions: https://github.com/agilira/harpocrates/blob/main/keyutils.go#L185-L210 encryption.go nonce generation in EncryptBytes(): https://github.com/agilira/harpocrates/blob/main/encryption.go#L154-L158 streaming.go nonce generation for streaming encryption: https://github.com/agilira/harpocrates/blob/main/streaming.go#L155 All functions use io.ReadFull(rand.Reader, ...) where rand refers to crypto/rand, ensuring cryptographically secure random generation for all security-critical operations.

Harpocrates uses secure delivery mechanisms that counter MITM attacks through multiple layers:

Go Module Proxy (HTTPS): Distributed via https://proxy.golang.org with cryptographic integrity verification through sum.golang.org GitHub Repository (HTTPS/SSH): Source code hosted at https://github.com/agilira/harpocrates with HTTPS and SSH access options Cryptographic Verification: Go modules automatically verify checksums in go.sum file to detect tampering Installation Command: go get github.com/agilira/harpocrates uses secure HTTPS transport with integrity checks Evidence:

Installation instructions: https://github.com/agilira/harpocrates/blob/main/README.md#installation Go module configuration: https://github.com/agilira/harpocrates/blob/main/go.mod Checksum verification: https://github.com/agilira/harpocrates/blob/main/go.sum All distribution channels use HTTPS or SSH with cryptographic verification, meeting OpenSSF requirements for MITM attack prevention.

Harpocrates does not retrieve cryptographic hashes over HTTP and use them without checking cryptographic signatures. All hash verification is done through secure mechanisms:

Go Module System: Uses cryptographically verified checksums in go.sum with automatic verification via sum.golang.org GPG-Signed Releases: All release tags are GPG-signed as documented in the release process HTTPS-Only Distribution: All dependencies and tools are obtained via HTTPS or secure Go module proxy No Insecure Hash Downloads: Zero scripts or processes download .sha1, .sha256, or other hash files over HTTP Evidence:

Secure dependency management: https://github.com/agilira/harpocrates/blob/main/go.sum GPG-signed release process: https://github.com/agilira/harpocrates/blob/main/docs/release-process.md#verification-process Makefile with secure tool installation: https://github.com/agilira/harpocrates/blob/main/Makefile#L84-L89 The project relies exclusively on Go's built-in cryptographic verification system and GPG signatures, never downloading or using hashes from insecure HTTP sources.
