# 🆘 SeedPGP Offline Recovery Playbook
**EMERGENCY SEED RECOVERY WITHOUT THE SEEDPGP WEB APP**
---
## 📋 What This Document Is For
You created an encrypted backup of your cryptocurrency seed phrase using SeedPGP. This document explains **how to decrypt that backup if the SeedPGP web app is no longer available** (website down, GitHub deleted, domain expired, etc.).
**Print this document and store it with your encrypted QR backup.**
---
## 🎯 Quick Reference: What You Need
Depending on how you encrypted your backup, you need:
| Encryption Method | What You Need to Decrypt |
|-------------------|--------------------------|
| **Password-only** | Password + this playbook + any computer with GPG |
| **PGP Public Key** | Private key + private key passphrase + this playbook + any computer with GPG |
| **Krux KEF format** | Passphrase + Python 3 + this playbook |
---
## 🔍 Step 1: Identify Your Backup Format
Look at your encrypted backup. The format determines which recovery method to use:
### **Format A: SeedPGP Standard (PGP)**
Your QR code or text starts with:
```
SEEDPGP1:0:A1B2:CDEFG...
```
**OR** your backup is a PGP armored message:
```
-----BEGIN PGP MESSAGE-----
hQEMA...
-----END PGP MESSAGE-----
```
➜ **Use Method 1: GPG Command-Line Recovery** (see below)
---
### **Format B: Krux KEF**
Your QR code or text starts with:
```
KEF:1234+ABCD...
```
**OR** it's a Base43-encoded string using only these characters:
```
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ$%*+-./:
```
➜ **Use Method 2: Python Krux Decryption** (see below)
---
### **Format C: Plain SeedQR** (NOT ENCRYPTED)
Your QR is all digits (48 or 96 digits for 12/24 words):
```
0216007100420461...
```
**OR** all hex (32 or 64 hex characters):
```
1a2b3c4d5e6f...
```
➜ **Use Method 3: SeedQR Decoder** (see below)
---
## 📖 Method 1: GPG Command-Line Recovery (PGP Format)
### **What You Need:**
- ✅ Your encrypted backup (QR scan result or PGP armored text)
- ✅ Your password (if password-encrypted)
- ✅ Your PGP private key + passphrase (if key-encrypted)
- ✅ A computer with GPG installed (Linux/Mac: pre-installed, Windows: download Gpg4win)
---
### **Step 1A: Extract the PGP Message**
If your backup is a `SEEDPGP1:...` QR string, you need to decode it first:
```bash
# Your QR scan result looks like:
# SEEDPGP1:0:A1B2:BASE45_ENCODED_DATA_HERE
# Extract just the Base45 part (everything after the third colon)
echo "SEEDPGP1:0:A1B2:BASE45DATA" | cut -d: -f4- > base45.txt
# Decode Base45 to binary PGP (requires Python script - see Appendix A)
python3 decode_base45.py base45.txt > encrypted.pgp
```
If your backup is already a PGP armored message (`-----BEGIN PGP MESSAGE-----`), save it to a file:
```bash
cat > encrypted.asc << 'EOF'
-----BEGIN PGP MESSAGE-----
hQEMA...
-----END PGP MESSAGE-----
EOF
```
---
### **Step 1B: Decrypt with GPG**
**If encrypted with PASSWORD only:**
```bash
# Decrypt using password
gpg --decrypt encrypted.pgp
# OR if you have the armored version:
gpg --decrypt encrypted.asc
# GPG will prompt: "Enter passphrase:"
# Type your password exactly as you created it
# Output will be JSON like: {"v":1,"t":"bip39","w":"word1 word2 word3...","l":"en","pp":0}
```
**If encrypted with PGP PUBLIC KEY:**
```bash
# First, import your private key (if not already in your GPG keyring)
gpg --import my-private-key.asc
# Decrypt
gpg --decrypt encrypted.pgp
# GPG will prompt for your PRIVATE KEY PASSPHRASE (not the backup password)
# Output will be JSON like: {"v":1,"t":"bip39","w":"word1 word2 word3...","l":"en","pp":0}
```
---
### **Step 1C: Extract Your Seed Phrase**
The decrypted output is JSON format:
```json
{"v":1,"t":"bip39","w":"abandon ability able about above...","l":"en","pp":0}
```
**Your seed phrase is the value of the `"w"` field.**
Extract it:
```bash
# If output is in a file:
cat decrypted.json | grep -o '"w":"[^"]*"' | cut -d'"' -f4
# Or use Python:
python3 -c 'import json; print(json.load(open("decrypted.json"))["w"])'
```
**Write down your seed phrase immediately on paper.**
---
### **JSON Field Meanings:**
| Field | Meaning | Example Value |
|-------|---------|---------------|
| `v` | Format version | `1` |
| `t` | Mnemonic type | `"bip39"` |
| `w` | **Your seed phrase (words)** | `"abandon ability able..."` |
| `l` | Language | `"en"` (English) |
| `pp` | BIP39 passphrase used? | `0` (no) or `1` (yes) |
| `fpr` | Recipient PGP fingerprints | `["ABC123..."]` (optional) |
**If `pp` is `1`:** You used a BIP39 passphrase in addition to your seed words. You need BOTH to restore your wallet.
---
## 🐍 Method 2: Python Krux Decryption (KEF Format)
### **What You Need:**
- ✅ Your Krux KEF backup (QR scan result starting with `KEF:` or Base43 string)
- ✅ Your passphrase
- ✅ A computer with Python 3
---
### **Step 2A: Prepare the Decryption Script**
Save this Python script as `decrypt_krux.py`:

## 📱 Method 3: SeedQR Decoder (Unencrypted Format)
### **What You Need:**
- ✅ Your SeedQR backup (all digits or hex)
- ✅ BIP39 wordlist (see Appendix B)
- ✅ Optional: Python script (see below)
---
### **Step 3A: Identify SeedQR Type**
**Standard SeedQR (all digits):**
- 48 digits = 12-word seed
- 96 digits = 24-word seed
- Each 4 digits = one BIP39 word index (0000-2047)
**Compact SeedQR (hex):**
- 32 hex chars = 12-word seed
- 64 hex chars = 24-word seed
- Raw entropy encoded as hexadecimal
---
### **Step 3B: Manual Decoding (Standard SeedQR)**
**Example:** `0216007100420461...` (48 digits for 12 words)
1. Split into 4-digit chunks: `0216`, `0071`, `0042`, `0461`, ...
2. Each chunk is a word index (0-2047)
3. Look up each index in the BIP39 wordlist (Appendix B)
```
0216 → word #216 = "brick"
0071 → word #71 = "appear"
0042 → word #42 = "advise"
0461 → word #461 = "dove"
...
```
**Your seed phrase is the words in order.**
---
### **Step 3C: Python Script (Standard SeedQR)**
Save as `decode_seedqr.py`:
```python
#!/usr/bin/env python3
"""SeedQR to BIP39 Mnemonic Decoder"""
# BIP39 English wordlist (2048 words)
# Download from: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

try:
from mnemonic import Mnemonic
mnemo = Mnemonic("english")
entropy = bytes.fromhex(qr_hex)
return mnemo.to_mnemonic(entropy)

print("ERROR: 'mnemonic' library required for compact SeedQR")
print("Install: pip3 install mnemonic")

## 📚 Appendix A: Base45 Decoder
If you need to decode SeedPGP's Base45 format manually, save this as `decode_base45.py`:
```python
#!/usr/bin/env python3
"""Base45 Decoder for SeedPGP Recovery"""
B45_CHARS = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ $%*+-./:"
def base45_decode(s):
"""Decode Base45 string to bytes"""
result = []
i = 0
while i < len(s):
if i + 2 < len(s):
# Process 3 characters → 2 bytes
c = B45_CHARS.index(s[i])
d = B45_CHARS.index(s[i+1])
e = B45_CHARS.index(s[i+2])
x = c + d * 45 + e * 45 * 45
result.append(x // 256)
result.append(x % 256)
i += 3
else:
# Process 2 characters → 1 byte
c = B45_CHARS.index(s[i])
d = B45_CHARS.index(s[i+1])
x = c + d * 45
if x > 255:
raise ValueError("Invalid Base45 encoding")
result.append(x)
i += 2
return bytes(result)
if __name__ == "__main__":
import sys
if len(sys.argv) > 1:
# Read from file
with open(sys.argv[1]) as f:
b45_input = f.read().strip()
else:
# Read from stdin
b45_input = input("Paste Base45 data: ").strip()
try:
decoded = base45_decode(b45_input)
sys.stdout.buffer.write(decoded)
except Exception as e:
print(f"ERROR: {e}", file=sys.stderr)
exit(1)

## 🛡️ Security Recommendations
### **When Recovering Your Seed:**
1. ✅ **Use an air-gapped computer** (TailsOS or Ubuntu Live USB)
2. ✅ **Disconnect from internet** before decrypting
3. ✅ **Write seed on paper immediately** after decryption
4. ✅ **Never screenshot or save to disk**
5. ✅ **Verify your seed** by importing to a test wallet (small amount first)
6. ✅ **Destroy digital traces** after recovery (shutdown amnesic OS)
### **Storage Best Practices:**
- 📄 **Print this document** and store with your encrypted backup
- 🔐 Store backup + recovery instructions in different locations
- 💾 Keep a copy of Python scripts on offline USB
- 📦 Include a copy of the BIP39 wordlist (offline reference)
- 🗂️ Label everything clearly: "SEEDPGP BACKUP + RECOVERY GUIDE - DO NOT LOSE"
---
## 🆘 Emergency Contact
**If you're stuck:**
1. Search GitHub for "seedpgp-web" (project may still exist)
2. Check Internet Archive: https://web.archive.org/
3. Ask in Bitcoin/crypto forums (describe format, don't share actual data!)
4. Hire a professional cryptocurrency recovery service (last resort)
**Never share:**
- ❌ Your encrypted backup data with strangers
- ❌ Your password or passphrase
- ❌ Your PGP private key
- ❌ Your decrypted seed phrase
---
## ✅ Recovery Checklist
Before attempting recovery, verify you have:
- [ ] This printed playbook
- [ ] Your encrypted backup (QR code or text file)
- [ ] Your password/passphrase written down
- [ ] Your PGP private key (if used) + passphrase
- [ ] An air-gapped computer (TailsOS/Ubuntu Live recommended)
- [ ] GPG installed (for PGP decryption)
- [ ] Python 3 + libraries (for Krux/SeedQR decryption)
- [ ] BIP39 wordlist (for manual SeedQR decoding)
- [ ] Paper and pen (to write recovered seed)
**If missing any item above, DO NOT PROCEED. Secure it first.**
---
## 📅 Recommended Practice Schedule
**Every 6 months:**
1. Test that you can still decrypt your backup
2. Verify the recovery tools still work
3. Update this playbook if formats change
4. Check that your passwords/keys are still accessible
**Test with a dummy backup first!** Create a test seed, encrypt it, then practice recovery.
