feat: Phase 4 Tasks 3-4 - CLI encryption integration
...
Integrated encryption into backup workflow:
cmd/encryption.go:
- loadEncryptionKey() - loads from file or env var
- Supports base64-encoded keys (32 bytes)
- Supports raw 32-byte keys
- Supports passphrases (PBKDF2 derivation)
- Priority: --encryption-key-file > DBBACKUP_ENCRYPTION_KEY
cmd/backup_impl.go:
- encryptLatestBackup() - finds and encrypts single backups
- encryptLatestClusterBackup() - encrypts cluster backups
- findLatestBackup() - locates most recent backup file
- findLatestClusterBackup() - locates cluster backup
- Encryption applied after successful backup
- Integrated into all backup modes (cluster, single, sample)
internal/backup/encryption.go:
- EncryptBackupFile() - encrypts backup in-place
- DecryptBackupFile() - decrypts to new file
- IsBackupEncrypted() - checks metadata/file format
- Updates .meta.json with encryption info
- Replaces original with encrypted version
internal/metadata/metadata.go:
- Added Encrypted bool field
- Added EncryptionAlgorithm string field
- Tracks encryption status in backup metadata
internal/metadata/save.go:
- Helper to save BackupMetadata to .meta.json
tests/encryption_smoke_test.sh:
- Basic smoke test for encryption/decryption
- Verifies data integrity
- Tests with env var key source
CLI Flags (already existed):
--encrypt Enable encryption
--encryption-key-file PATH Key file path
--encryption-key-env VAR Env var name (default: DBBACKUP_ENCRYPTION_KEY)
Usage Examples:
# Encrypt with key file
./dbbackup backup single mydb --encrypt --encryption-key-file /path/to/key
# Encrypt with env var
export DBBACKUP_ENCRYPTION_KEY="base64_encoded_key"
./dbbackup backup single mydb --encrypt
# Cluster backup with encryption
./dbbackup backup cluster --encrypt --encryption-key-file key.txt
Features:
✅ Post-backup encryption (doesn't slow down backup itself)
✅ In-place encryption (overwrites original)
✅ Metadata tracking (encrypted flag)
✅ Multiple key sources (file/env/passphrase)
✅ Base64 and raw key support
✅ PBKDF2 for passphrases
✅ Automatic latest backup detection
✅ Works with all backup modes
Status: ENCRYPTION FULLY INTEGRATED ✅
Next: Task 5 - Restore decryption integration
