SHA1 and MD5 are cryptographically broken. + +2. **Collision Resistance**: With 256-bit output, the probability of accidental collision is approximately 2^-128 (~10^-38). To have a 50% chance of collision, you would need approximately 2^128 unique files. + +3. **Industry Standard**: SHA256 is the de facto standard for content-addressable storage (Git, Docker, npm, etc.). + +4. **Performance**: While Blake3 is faster, SHA256 throughput (~400 MB/s) exceeds typical network bandwidth for uploads. The bottleneck is I/O, not hashing. + +5. **Tooling**: Universal support in all languages, operating systems, and verification tools. + +### Migration Path + +If a future algorithm change is needed (e.g., SHA3 or Blake3): + +1. **Database**: Add `hash_algorithm` column to artifacts table (default: 'sha256') +2. **S3 Keys**: New algorithm uses different prefix (e.g., `fruits-sha3/` vs `fruits/`) +3. **API**: Accept algorithm hint in upload, return algorithm in responses +4. **Migration**: Background job to re-hash existing artifacts if needed + +**Current Implementation**: Single algorithm (SHA256), no algorithm versioning required for MVP. + +--- + +## Content-Addressable Storage Model + +### Core Principles + +1. **Identity = Content**: The artifact ID IS the SHA256 hash of its content +2. **Immutability**: Content cannot change after storage (same hash = same content) +3. **Deduplication**: Same content uploaded twice results in single storage +4. **Metadata Independence**: Files with identical content but different names/types are deduplicated + +### Data Model + +``` +Artifact { + id: VARCHAR(64) PRIMARY KEY -- SHA256 hash (lowercase hex) + size: BIGINT -- File size in bytes + ref_count: INTEGER -- Number of references + s3_key: VARCHAR(1024) -- S3 storage path + checksum_md5: VARCHAR(32) -- Secondary checksum + checksum_sha1: VARCHAR(40) -- Secondary checksum + ... +} + +Tag { + id: UUID PRIMARY KEY + name: VARCHAR(255) + package_id: UUID FK + artifact_id: VARCHAR(64) FK -- Points to Artifact.id (SHA256) +} +``` + +### Hash Format + +- Algorithm: SHA256 +- Output: 64 lowercase hexadecimal characters +- Example: `dffd6021bb2bd5b0af676290809ec3a53191dd81c7f70a4b28688a362182986f` + +--- + +## S3 Key Derivation + +### Key Structure + +``` +fruits/{hash[0:2]}/{hash[2:4]}/{full_hash} +``` + +Example for hash `dffd6021bb2bd5b0...`: +``` +fruits/df/fd/dffd6021bb2bd5b0af676290809ec3a53191dd81c7f70a4b28688a362182986f +``` + +### Rationale for Prefix Sharding + +1. **S3 Performance**: S3 partitions by key prefix.
