Encrypt Decrypt Backup

Encrypt and decrypt BSV backup files (.bep format) using the bitcoin-backup CLI. Supports all backup types (BAP identity, wallet, ordinals, vault). Uses Flow's FLOW_BACKUP_PASSPHRASE and stores files in /.flow/.bsv/ following Flow's BSV convention.

Encrypt/Decrypt Backup

Encrypt and decrypt BSV backup files using the bitcoin-backup CLI (bbackup).

When to Use

Encrypt wallet JSON to secure .bep backup file
Decrypt .bep backup to read wallet data
Create BAP identity backups
Secure ordinals keys and payment keys
Store sensitive BSV data encrypted at rest

Supported Backup Types

All backups use .bep format (AES-256-GCM encryption):

BapMasterBackup - BAP identity (Type42 or Legacy)
BapMemberBackup - Individual BAP member
WifBackup - Single private key
OneSatBackup - Ordinals + Payment + Identity keys
VaultBackup - Encrypted vault
YoursWalletBackup - Yours Wallet format
YoursWalletZipBackup - Yours Wallet ZIP format

Usage

Run the encrypt or decrypt scripts:

# Encrypt a wallet JSON file
bun run /path/to/skills/encrypt-decrypt-backup/scripts/encrypt.ts wallet.json output.bep

# Decrypt a backup file
bun run /path/to/skills/encrypt-decrypt-backup/scripts/decrypt.ts backup.bep

# Decrypt to specific output file
bun run /path/to/skills/encrypt-decrypt-backup/scripts/decrypt.ts backup.bep wallet.json

Flow's BSV Convention

This skill follows Flow's BSV backup convention:

Storage Location: /.flow/.bsv/

backups/ - Encrypted .bep files
temp/ - Temporary decrypted files (auto-cleanup)
config.json - Backup registry

Security:

Uses FLOW_BACKUP_PASSPHRASE environment variable
Never hardcodes passwords
Auto-cleanup of temp files after operations
600k PBKDF2 iterations for strong encryption

Requirements

FLOW_BACKUP_PASSPHRASE environment variable must be set
bbackup CLI installed globally: bun add -g bitcoin-backup

CLI Reference

The bitcoin-backup CLI provides three commands:

bbackup enc <input> -p <password> -o <output> - Encrypt JSON to .bep
bbackup dec <input> -p <password> -o <output> - Decrypt .bep to JSON
bbackup upg <input> -p <password> -o <output> - Upgrade legacy backups

Error Handling

Password too short (min 8 chars) - Returns error
Invalid backup structure - Validation error
Wrong password - Decryption fails with error
Auto-detects backup type and iteration count
