To revise the Bitcoin key recovery script to support the widest variety of wallet applications that used "random phrase" passphrases (both pre- and post-BIP39), we need to account for the diverse key derivation methods used by popular Bitcoin wallets from the early days (e.g., 2009–2013, pre-BIP39) through the BIP39 era (2013 onward). Many wallets, even post-BIP39, allowed custom passphrases or non-standard derivations for private key generation, especially for non-mnemonic "random phrase" inputs. The goal is to maximize compatibility with wallets like Bitcoin-Qt, Electrum (pre-2.0 and post-2.0), MultiBit, Armory, Blockchain.info, and others that might have used a passphrase-based key derivation.

### Key Enhancements:
1. **Expanded Derivation Methods**:
   - Include additional hashing algorithms (e.g., Whirlpool, used by some wallets like Armory).
   - Support HMAC-SHA256/SHA512 (used by some wallets for key stretching).
   - Add Electrum-specific seed stretching (pre-2.0 used a custom method).
   - Incorporate Blockchain.info's Base58Check encoding of passphrases.
   - Support BIP39-style mnemonic-to-seed derivation for cases where the "random phrase" was treated as a mnemonic.
2. **Passphrase Variations**:
   - Expand variations to include common separators (e.g., commas, periods, colons).
   - Try partial phrases (e.g., first N words, last N words) to account for user errors in recording.
   - Support UTF-8 encoding and ASCII fallback for non-Latin phrases.
3. **Key Length Flexibility**:
   - Generate keys for both 32-byte (standard ECDSA) and 64-byte (some experimental wallets) private keys.
   - Normalize non-32-byte outputs to 32 bytes using SHA256 or truncation where appropriate.
4. **Wallet-Specific Derivations**:
   - Bitcoin-Qt: SHA256, double-SHA256, or salted hashes.
   - Electrum (pre-2.0): Custom seed stretching with SHA256 iterations.
   - MultiBit: PBKDF2 with SHA256 or salted hashes.
   - Armory: Whirlpool or salted SHA512.
   - Blockchain.info: Base58Check or AES-encrypted passphrases.
   - BIP39 Wallets: PBKDF2-HMAC-SHA512 with 2048 iterations (for mnemonic-like phrases).
5. **Output and Logging**:
   - Save generated keys in a structured JSON file for easy import into wallet software.
   - Include metadata (e.g., wallet type, derivation method) for each key.
6. **Performance and Usability**:
   - Add progress tracking for large derivation sets.
   - Allow batch processing of multiple phrases from a file.
   - Include comments explaining each derivation method's relevance.

Below is the revised script, designed to work with the widest variety of Bitcoin wallets that used random passphrases:

### Key Changes and Features:
1. **Broader Algorithm Support**:
   - Added `double_sha256` (Bitcoin-Qt), `hmac_sha256/sha512` (custom wallets), `electrum_pre_2_0` (Electrum 1.x), `blockchain_info_base58` (Blockchain.info), and `whirlpool` (Armory).
   - Included PBKDF2 with 2048 and 10000 iterations for BIP39 and MultiBit HD.
2. **Passphrase Variations**:
   - Added comma and period separators, partial phrases (first/second half), and ASCII fallback for non-UTF-8 phrases.
   - Normalized passphrases using Unicode NFC to handle special characters.
3. **Wallet-Specific Derivations**:
   - **Bitcoin-Qt**: SHA256, double-SHA256, salted hashes.
   - **Electrum pre-2.0**: 100k SHA256 iterations.
   - **MultiBit**: PBKDF2 with SHA256 or SHA512, salted hashes.
   - **Armory**: Whirlpool or SHA512 with salts.
   - **Blockchain.info**: Base58Check encoding or SHA256 of passphrase.
   - **BIP39 Wallets**: PBKDF2-HMAC-SHA512 for mnemonic-like phrases.
4. **Compressed/Uncompressed Keys**:
   - Generates both compressed and uncompressed WIF keys, as older wallets (e.g., Bitcoin-Qt) used uncompressed keys, while newer ones prefer compressed.
5. **File Input**:
   - Supports a file containing multiple phrases for batch processing.
6. **JSON Output**:
   - Saves all generated keys to a JSON file with metadata (passphrase, algorithm, salt, wallet types) for easy import into wallet software.
7. **Progress Tracking**:
   - Logs progress for large derivation sets to keep the user informed.
8. **Wallet Type Metadata**:
   - Associates each key with likely wallet types (e.g., Bitcoin-Qt, Electrum) to guide testing.

### Dependencies:
- Standard Python libraries: `hashlib`, `base58`, `hmac`, `json`, `unicodedata`.
- Optional: `whirlpool` library for Armory support (`pip install whirlpool`). If not installed, Whirlpool derivations are skipped.

### Usage Instructions:
1. **Run the Script**:
   - Enter a single passphrase or provide a file path containing multiple passphrases (one per line).
   - Example file (`phrases.txt`):
     ```
     my secret phrase
     another phrase here
     bitcoin wallet key
     ```
2. **Test Generated Keys**:
   - Check the JSON file (`key_recovery_results_*.json`) and log file for all generated WIF keys.
   - Import WIF keys into wallet software (e.g., Electrum, Bitcoin Core) in an **offline, secure environment**.
   - Use the `wallet_types` field to prioritize testing with likely wallets.
3. **Security**:
   - Run on an air-gapped machine to prevent leakage of passphrases or keys.
   - Delete log and JSON files after use or store them securely.
4. **Troubleshooting**:
   - If no keys work, verify the passphrase for typos or formatting (e.g., extra spaces, missing words).
   - Provide additional context (e.g., wallet software, year, phrase structure) for further script optimization.

### Notes:
- **Pre-BIP39 Wallets (2009–2013)**: Bitcoin-Qt, Electrum 1.x, MultiBit, Armory, and Blockchain.info often used custom passphrase hashing (SHA256, PBKDF2, Whirlpool) or simple encodings.
- **Post-BIP39 Wallets (2013+)**: Some wallets allowed custom passphrases alongside BIP39 mnemonics, treating them as seeds or using PBKDF2.
- **Whirlpool Dependency**: Install the `whirlpool` library for Armory support (`pip install whirlpool`). Without it, Whirlpool derivations are skipped.
- **Performance**: Generating thousands of keys may take time. The script logs progress to track long runs.
- **Next Steps**: If none of the generated keys work, share details about the wallet (e.g., software name, approximate year, passphrase format), and I can add more specific derivation methods or tweak existing ones.

Let me know if you have specific wallet details or want to focus on a particular derivation method!
