Brute Seed + Passphrase File

📋 Overview

Mode 6 combines Mode 1 (brute-force missing seed words) with a passphrase file. You know most of the seed phrase (with x placeholders for unknown words) and have a list of possible passphrases. wrecover tests every valid seed candidate against every passphrase in the list.

Use this mode when you are missing one or more seed words and are also unsure which passphrase was used, but have narrowed down the passphrase to a list of candidates.

💡 GPU Supported

Mode 6 fully supports GPU acceleration (CUDA and OpenCL) in the Pro version.

📄 File Formats

Partial mnemonic (`-ms`)

Pass the partial mnemonic as a quoted string. Use x (lowercase) as placeholder for each unknown word — exactly as in Mode 1.

# One unknown word at position 4

-ms "abandon ability able x above absent absorb abstract absurd accuse accident account"

# Two unknown words

-ms "abandon ability able about x absent x abstract absurd accuse accident account"

Passphrase file (`-pps`)

Plain text file, one passphrase candidate per line (.txt extension for new search). wrecover generates a .bin binary index at first run. On resume, supply the .bin path.

# passphrases.txt

New search — GPU (Pro)

wrecover -m 6  -ms "abandon ability able x above x absorb abstract absurd accuse accident account"  -pps passphrases.txt  -addr "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa"  -wlang en  -ws -wf recovery.wrec wp "this workfile password" -gpu -grid 2048 -gblock 256

Resume (provide .bin passphrase file)

 # CPU

            wrecover -wi -wf recovery.wrec -wp "this workfile password" -pps passphrases.bin

            # GPU (Pro)

            wrecover -wi -wf recovery.wrec -wp "this workfile password" -pps passphrases.bin -gpu -grid 2048 -gblock 256

⚡ Performance

Total work = (seed combinations) × (passphrase count). Seed combinations are processed at seed-recovery speed; for each valid seed, all passphrases are tested sequentially.

Hardware	12-word	18-word	24-word
CPU — per thread (Free & Pro)	3,000–4,000/sec	3,000–4,000/sec	3,000–4,000/sec
NVIDIA Tesla T4 (Pro)	~2.6M/sec	~9.8M/sec	~21M/sec
NVIDIA RTX PRO 6000 (Pro)	~31.4M seeds/sec	~117.2M seeds/sec	~264M seeds/sec
N× GPUs (Pro)	Linear: N × single-GPU throughput

💡 Free vs Pro

Free: CPU only, max 10 threads. Pro: unlimited threads + GPU. Throughput scales linearly with thread count on CPU.
