RAR Password Recovery. 137,000 Passwords per Second on GPU.
Accent RAR Password Recovery finds the forgotten password. You unlock the archive files.
RAR encryption has no known vulnerabilities: the only way to crack a forgotten RAR3 or RAR5 password (WinRAR 2.90–7.x) is to brute-force it. On a CPU, that means thousands of passwords per second. AccentRPR runs GPU-accelerated brute force on NVIDIA, AMD, and Intel Arc graphics cards, checking 137,000 passwords per second for RAR5 on an RTX 5070 Ti. A positional mask and dictionary mutations narrow the search range.

RAR Password Recovery: How It Works in AccentRPR
Supported RAR Formats
AccentRPR handles RAR3 (WinRAR 2.90–4.x) and RAR5 (WinRAR 5.0–7.x) archives, including both compression methods: Lempel-Ziv and PPMd. The encryption type is detected automatically when you open the file.
RAR3 and RAR5 use different encryption, and that directly affects recovery speed. RAR5 brute-force speed is consistent. RAR3 slows down as password length increases: the longer the password, the more hashing rounds per candidate.
Compatibility table: encryption, key stretching, recovery methods
Password Recovery Speed on CPU
Three factors determine RAR password recovery time: the archive's encryption type, password length, and CPU performance. AccentRPR squeezes every bit of speed out of the processor: performance-critical code is written in assembly with SSE, AVX, and AES-NI support.
On an Intel Core Ultra 9 285K, AccentRPR checks roughly 12,000 passwords per second for RAR3 and 7,182 for RAR5. What do these numbers mean? A six-character password made of letters and digits (62 characters per position) adds up to 56.8 billion combinations. An exhaustive search for RAR5 on this CPU would take about 91 days. For RAR, GPU acceleration is not just helpful, it is critical.
| Vendor | Architectures | Models | Pro Series |
|---|---|---|---|
| NVIDIA (CUDA) | Maxwell → Blackwell | GeForce GTX 750 – RTX 50 | Tesla |
| AMD (OpenCL) | GCN → RDNA 4 | Radeon HD 7000 – RX 9000 | FirePro |
| Intel (OpenCL) | Xe → Xe2 | Arc A310 – Battlemage | — |
GPU Acceleration: NVIDIA, AMD, Intel Arc
A graphics card brute-forces passwords an order of magnitude faster than a CPU. An NVIDIA RTX 5070 Ti checks 137,000 passwords per second for RAR5, a Radeon RX 9070 XT 124,000, an Intel Arc B580 80,000. A Core Ultra 9 285K on the same task delivers 7,182.
91 days on a CPU for a six-character password? On an RTX 5070 Ti the same search takes about 5 days. Two cards in the system cut that time in half, three cut it to a third.

Positional Mask for Brute Force
A positional mask defines the allowed characters for each position in the password individually, narrowing the search range by thousands of times. AccentRPR tests only the combinations that match the mask.
Example. An eight-character password made of letters and digits (62 characters per position) adds up to 218 trillion combinations. On an RTX 5070 Ti, an exhaustive RAR5 search would take about 50 years. If you know the first four characters are lowercase letters and the last four are digits, the mask shrinks the range to 4.57 billion. The same GPU gets through them in 9 hours.
Dictionary Mutation and Blending
A dictionary attack with mutations tests realistic passwords rather than random character strings: words, dates, names, and their combinations with substitutions and additions. AccentRPR blends up to four dictionaries and transforms password candidates according to mutation rules.
The words password and 2026 from two separate dictionaries produce password2026 and dozens of mutations:
Password2026, p@ssw0rd2026, PASSWORD2026!, and so on. The macro language supports over
20 transformation rules. The Rule Editor previews each mutation as you set it up.
Password Completely Forgotten: Attack Scenarios
An attack scenario builds a recovery strategy from the most likely passwords to the least likely, gradually expanding the search range. For example, a dictionary with mutations first, then a positional mask for 6 characters, then 7, then 8. You define the strategy in a text file, launch it once, and get results without switching between attacks manually.

Who Uses AccentRPR
Home users recover forgotten passwords to personal archives: a positional mask and dictionary mutations cut the search from years to hours.
IT departments regain access to work files when a password left with a former employee – attack scenarios work through the options without manual oversight.
Forensic investigators rely on keyspace estimation and time projections for case planning, while CLI integrates AccentRPR into the investigation workflow.

Frequently Asked Questions
How Long Does It Take to Recover a RAR Password?
It depends on password length, character set, and hardware. On an NVIDIA RTX 5070 Ti, AccentRPR checks 137,000 passwords per second for RAR5. A 4-character password (letters and digits) is found in about 2 minutes, a 6-character one in 5 days, an 8-character one in decades.
| Password length | Digits (10) | Lowercase (26) | Letters + digits (62) | Full ASCII (95) |
|---|---|---|---|---|
| 4 characters | < 1 sec | a few sec | ~2 min | ~10 min |
| 6 characters | a few sec | ~38 min | ~5 days | ~2 months |
| 8 characters | ~12 min | ~18 days | ~50 years | centuries |
| 10 characters | ~20 hours | ~33 years | millennia | ∞ |
RAR5, exhaustive search on NVIDIA RTX 5070 Ti (137,148 passwords/sec). On an Intel Core Ultra 9 285K CPU (7,182 passwords/sec), multiply the time by roughly 19.
A positional mask and dictionary mutations drastically cut the search when at least the password structure is known. A random password longer than 8 characters with RAR5 encryption is unrealistic to recover on current hardware.
Can You Open a Password-Protected RAR Without the Password?
No. RAR encryption has no known vulnerabilities. The only way to access the files is to recover the password by brute force.
AccentRPR brute-forces passwords on CPU and GPU, utilizing every NVIDIA, AMD, and Intel Arc graphics card in the system. The software runs locally: your archive is never uploaded to any server and confidentiality is preserved.
Even a budget NVIDIA GTX 1650 Super checks 27,000 passwords per second for RAR5.
What Is the Difference Between RAR3 and RAR5 for Password Recovery?
RAR3 and RAR5 use different encryption algorithms, and that directly affects brute-force speed. RAR5 (AES-256, PBKDF2) delivers consistent speed regardless of password length. RAR3 (AES-128, SHA-1) requires more hashing rounds as the password gets longer, so long passwords in RAR3 are actually slower to crack than in RAR5.
AccentRPR detects the archive format automatically when you open the file. Both formats are supported with recovery on CPU and GPU.
Is It Legal to Recover a RAR File Password?
Recovering the password to your own files or to files owned by your organization is legal. A former employee left without handing over passwords to work archives, a personal archive was created years ago and the password is forgotten: AccentRPR covers both situations. The software is used by individual users, corporate IT departments, and forensic agencies in the course of legal proceedings.
Responsibility for how the software is used rests with the user. Terms are described in the license agreement.
Can You Remove the Password from a RAR File?
You cannot remove the password from an encrypted RAR archive directly. First you need to recover the password, then extract the archive in any archiver (WinRAR, 7-Zip) and repack the files without a password if needed.
AccentRPR handles the first and hardest step: finding the forgotten password. After that, the archive opens in whatever archiver you already use.
What GPU Do I Need for RAR Password Recovery?
AccentRPR supports NVIDIA (Maxwell and newer, from GeForce GTX 750 through RTX 50), AMD (GCN and newer, from Radeon HD 7000 through RX 9000), and Intel Arc (Xe, Xe2) graphics cards. Professional series like NVIDIA Tesla and AMD FirePro are also supported.
Password recovery speed is determined by two GPU parameters: the number of compute units (SP/ALU) and their clock frequency. That is why top-end gaming cards often outperform professional series. To compare models, see the GPU rating for password recovery. The AccentRPR demo shows exact speed on your hardware.
